I welcome you for the module 5 lecture 2 in the series of lectures on surface finish measurement. In this lecture we will be discussing about the various parameters which are used to specify the surface roughness and we will also study about the different methods of surface finish measurement like contact methods and non-contact methods. And also we will study about the various elements of stylus type instruments. We will discuss about the types of skids and the design of stylus and the out of phase condition of the skid. And then we will also learn how to select the measuring parameters like cutoff length and then finally we will see some experiments. Now we will start with this parameters roughness parameters. So first one is RA roughness average which is also known as central line average. I can see here after getting the profile the workpiece surface is kept on the table of the measuring instrument and the stylus will move on the surface and finally we get the profile as output from the measuring instrument. Now we have to analyze this profile. In order to analyze this profile we can see at we have to select the length, sampling length L and we have to draw the ordinates h1, h2, h3, h4 up to hn at equal distance and then we have to measure the heights of these ordinates and then finally we should find the summation of heights like that is h1 plus h2 plus h3 up to hn divided by number of ordinates. So this will give the RA value. If ordinates are measured in terms of micrometers then we get the RA value in terms of micrometers. So another way of, see in the previous case you can see here when we select the ordinates at regular intervals some of the important ordinates we may miss. For example here we have this peak. So this peak will be losing similarly if we draw the h7 here. So we will be losing this valley depth. So we get a value which is somewhat erroneous in order to and also it is difficult to draw too many ordinates at very close spacing and it becomes difficult to measure. So we have another parameter RA which can be analyzed by means of measuring the areas. You can see here we have the main line or central line and below the central line we have areas a1, a3, a5 etc and above the central line we have areas a2, a4, a6 up to an. Now these areas can be measured using the planimator so that measurement of ordinates is avoided. So accurately we can measure the areas using planimator and then we can measure, we can calculate the summation of all the areas divided by the length. So this will give us RA value. So what are the advantages of using the RA parameter? This is most commonly used parameter to monitor the production processes. So this is the default parameter on a drawing if the parameter is not specified. So this RA parameter is available in almost all commercially available surface finish measuring instruments and this is statistically very stable and repeatable parameter. And this is very good for random type of surfaces such as grinding ground surface, a good parameter where a process is under control and where the conditions are always same like cutting tapes, plates, plates etc are same then this parameter is better to use. And disadvantage of RA is not, this is not a good discriminator of different types of surfaces. So no distinction is made between peaks and valleys. Now another parameter is RQ, root mean square roughness. So in this case instead of taking only h1, h2 values the squares of ordinates are taken like this h1 square plus h2 square plus h3 square like this divided by number of ordinates under square. So this will give us RQ. RQ is typically 11 to 15% higher than RA and RQ is more sensitive to peaks and valleys than RA because the amplitudes are squared. And this is used to control very fine surfaces in the scientific measurements and statistical evaluations. Now the next parameter is RY, this is also known as RMAX, you can see here this is the profile that is obtained over a sampling, a particular sampling length. Now the gap between the peak and the valley within the sampling length is termed as RMAX or RY. So it is the vertical distance between the top of highest peak and the bottom of deepest valley within the sampling length. Now this is RZ, so we have the evaluation length which is divided into 5 equal parts. So we have 5 sampling lengths RZ1, RZ2, RZ3, RZ4 and RZ5 and in each sampling length we have to find the peak to valley distance, now this is RZ1, similarly peak to valley in the second sampling length there is RZ2, RZ3 like this. Now after finding RZ1, RZ2 up to RZ5 the average peak to valley profile is calculated, so that is RZ. Now this is more sensitive than RA to changes in the surface finish as maximum profile heights and not averages are being examined. RMAX is useful for surfaces where a single defect is not permissible, for example a seal with a single scratch, if there is a scratch and a seal that also will be considered. So if it exceeds, if the RMAX exceeds a certain limit then that particular seal is rejected. And then RZ and RMAX are used together to monitor the variations of surface finish in production processes. So similar values of RZ and RMAX indicate a consistent surface finish while a significant difference indicates a surface defect in an otherwise consistent surface. Now here we can see a profile in which we have considered 5 sampling lengths RZ1, RZ2, RZ3, RZ4 and RZ5. We can see here in RZ1 value is 3.2 micrometer that we can see here this is the peak in this particular sampling length and this is the valley. So this distance is about 1.6 micrometers and this is about 1.6 micrometers. So when we add these two we get 3.2 micrometers. Similarly the RZ value for this particular sampling length is this one. So here this is 2 micrometer and here it is 2 micrometer. So peak to valley distance is 4 micrometers. Similarly RZ3 is 4.1 and RZ4 is 2.9 and RZ5 is 3. So when we calculate the average of these 5 values we get this RZ of 3.5 micrometer this is the average RZ value. Now coming to the next parameter this is RP. Now this is the gap this is the highest peak the maximum distance between the center line and the highest peak is termed as RP within the given sampling length. Also the distance between the center line and the lowest valley is known as RV value and then RT this is maximum peak to valley height the absolute value between the highest and the lowest peaks. So RT is equal to RP plus RV when we add these two we get RT value. So next one is RTM mean RT mean peak to valley roughness. Now we can see here we have this evaluation length which is divided into 5 sampling lengths and this is the first sampling length in which we have peak to valley distance it is nothing but Z1. Similarly the second sampling length we have Z2 this is the peak to valley gap similarly Z3 Z4 Z5. So when we calculate the average of these 5 values we get RT mean peak to valley roughness and then this is Pt value total peak to valley profile. So over the evaluation length the gap between the top most point and the peak peak and the lowest point and this gap is total peak to valley profile height. And we have another parameter 10 point average 10 point height average is also known as RZ value RZ parameter. So again in the evaluation length we have to consider 5 peaks you can see here in this profile P1 P2 P3 P4 and P5. Highest peaks are considered within the evaluation length similarly 5 lowest valleys are considered you can see here P1 P2 P3 P4 and P5 and now the average absolute value of the 5 highest peaks and the 5 lowest valleys over the evaluation length will give us RZ value that means we have to add the ordinates P1 P2 P3 P4 P5 and minus the summation of ordinates V1 V2 V3 V4 V5 then if we feed these values in this expression we get RZ value 10 point average height average value. So now coming to the waviness parameters so this is a waviness is a larger component of surface texture upon which roughness is superimposed like we have the surface roughness and then we have this waviness. So this profile will give us waviness profile and the parameter that is used to specify this waviness is waviness height that is the maximum height of waviness data within the evaluation length this is the evaluation length and this is the peak and valley so this gap is known as waviness height and it is specified by the symbol wt. So this waviness height parameter is used where in addition to roughness waviness is also critical. Now moving to the spacing parameters we have this parameter PC we have this profile wherein we have peaks 1, 2, 3, 4 etc and valleys 1, 2, 3, 4, 5 etc. So this PC it is nothing but peak count or number of peaks included in the analysis of the profile a peak is defined as a data point whose height is above a software selected bandwidth this is the software selected bandwidth and we have some peaks above this bandwidth so these are considered for the calculating the PC. So if we consider an area of surface then the number of peaks per unit area that is termed as peak density and other term is yes this is the average spacing between local peaks over the evaluation length. Now we can see here in this profile we have the evaluation length and we have peaks here one peak and second peak this is the gap between two peaks similarly we have considered one more peak here and another peak here this distance between this peak and this peak is s2 and similarly distance between this peak and this peak is s3 and so like this we have to measure the gaps these gaps that is spacing between the peaks and then we should find the average spacing using this expression. So varying s is equal to s1 plus s2 up to s6 divided by if we consider 6 peaks then s1 plus s2 up to 6 divided by number of peaks considered so this will give the average spacing. So now having understood the various parameters used to specify the roughness we will move to the measurement of surface roughness how we can measure the surface roughness how we can get the various parameter values and what are the kinds of measuring methods used what are the different types of measuring instruments so those things we will study. So roughness may be measured using any one of the following methods so we can measure the surface roughness of the component in the offline method that is after the production is over the part is taken out of the machine tool and it is de-oiled and deburred and then it is kept in the proper atmospheric temperature condition and then appropriate instrument is selected and then the surface is measured to get the various parameters. So in the offline methods we have different we have contact type and non-contact type measurement methods so in the contact type so we have stylus probe type instrument and macrin 3 instrument and in the non-contact type offline method we have optical systems like tool makers microscope can be used to analyze the surface and then we have laser based system which works on reflected light intensity method and then image processing systems are also available and then we can also use some comparison standards. Using comparison standards we can check the surface under question so we can use the visual examination or tactile examination so we will also learn about the comparison standards and then there are in process measurement method that means when the workpiece is being machined we can measure the surface finish without unloading the workpiece from the machining setup. So many methods are being used to measure the surface roughness during machining is in process so we can use machine vision system or inductance method in the machine vision the light source is used to eliminate the surface with a digital system to view the surface and the data being sent to computer for analysis. The digitized data is then used with a correlation chart to get the actual roughness values that means initially we should use some standard specimens whose surface roughness is known and then using those standard specimens we can calibrate the machine vision system that means for a particular surface roughness what is the digital data we get like that we can calibrate and then we can use the component for which surface is to be tested we should keep them under machine vision and then what is the digital signal we obtained and then that should be compared with the digital data obtained from the standard specimen. So that is the method used in machine vision system and inductance method is also used in which pickup is used inductance pickup is used to measure the distance between the surface and the pickup this measurement gives a parametric value that may be used to give a comparative roughness so it will be something like this we have the workpiece which is being machined and then we can always use in inductance pickup as the surface roughness varies this gap will be varying so that gap is sensed and the signal is sent out by the inductance pickup which is supplied to the computer for analyzing the surface roughness and ultrasound systems are also used a spherically focused ultrasonic sensor is positioned with a non normal incidence angle above the surface so it is something like this so this is the workpiece and then ultrasonic sensor is positioned in non normal incidence angle ok which is not normal to the surface and then the reflected sound wave is sensed by another receiver and the signal is sent to the computer for analyzing the surface. So when the due to the asperities the reflected sound wave characteristic will change so which is used to calculate the surface roughness and then we have pneumatic method so this we will study we will discuss after sometime now let us study some of the stylus probe instruments or the design of stylus probe and what are the various elements of stylus type instruments I can see here we have the surface being measured we have asperities peaks and valleys etc etc and then we have a stylus here a pointed stylus so that pointed stylus is made to move on the surface under question and because of these asperities the stylus will move up and down ok and then because of this up and down moment here we have a pickup so the design and construction of these this pickup will study later the stylus will move up and down and the pickup will give the signal which is sent to the computer for analysis purpose. This stylus tip it has a very small radius of 5 to 10 micrometer and normally it is made out of diamond material to resist the wear now pointed probe is drawn slowly over the surface again the movement is made probe is made to move at a particular slow speed and then the variations due to variations stylus will move and then the signal is digitized and it is sent for the computer sent to the computer for analysis purpose in the commercially available instruments there are magnification switches depending upon the surface whether it is rough turned surface or shaped surface or milled surface or ground surface or lapped surface so depending upon the machining process used so magnification switch magnification can be selected for lapped surface very high magnification is used whereas for rough turned surface very low magnification is enough also we can specify what is the cutoff length or sampling length depend again this is again depending upon the machining process that is selected if it is grinding process lapping process so where in the we get fine surface cutoff very small cutoff length of less than 0.8 millimetre is used so if it is rough surface turned surface or milled surface we can use cutoff length of 0.8 or 2.5 like that so the cutoff length selection we will discuss again after sometime the instrument will display the various surface finish parameters like RA, RP, RT etc etc there is a display device also we can get the print out of the profile the profile print we can obtain at different magnification values now here you can see a commercially available instrument so you can see the various buttons this the button to start the instrument switch on the instrument and then for starting the movement of the stylus and you can see this is the display device and the cutoff length selected is 2.5 millimetre and you can see it is now it is showing RA value 0 micro meter so different by operating this data point different parameters we can select and the value of that particular parameter is displayed here and we can see the probe here the pick up pick up we can see here so which will move on the surface and then the data that is obtained is analysed and then the particular parameter is calculated and then it is displayed so in this case there is no printer it is only display device now what are the various elements of a stylus type instrument I can see here this is the surface under question which is to be measured and then we have stylus here a diamond point and then we have pick up here the details of pick up will study after some time and there is a traverse unit or in other words drive unit so this stylus should be made to move on the surface at a predefined speed so we need to have a driving unit so this is the driving unit to move the pick up and the signals given by this stylus they are amplified and an appropriate filters are used for example if we want only waviness that can be indicated here if we want only the roughness parameter we can filter out the waviness and sometimes we have to eliminate the form error also so for such a thing different kinds of filters are used and finally the value is indicated or the roughness parameter is indicated or waviness parameter is indicated depending upon the requirement and here you can see there is a cutoff length selector depending upon the machining process we can select appropriate cutoff length also we have a switch to select the appropriate magnification so if the surface is very fine lapped surface then we should use very high value of vertical magnification if it is rough surface we can lower the vertical magnification and you can see the printer attachment is also there so we can get a print of the profile now you can see a commercially available setup here this is the workpiece for which surface finish is to be measured and then this is the instrument stylus type instrument and this is the probe and now you can see depending upon the height of the workpiece we have to adjust the height of this instrument otherwise there will be error in the measured value so for adjusting the height you can see a stand is provided so depending upon the height of the workpiece we have to adjust the height of this instrument and then the it is connected to a printer and display device so here various buttons are there to select the appropriate magnification cutoff length and what type of what are the various parameters needed etc. can be selected here and then the value the selected parameter is displayed as well as the profile print we can obtain now how the data is processed you can see here we have a flow chart here so the real surface profile now this is the real profile surface which is to be measured which is to be analyzed and then we have to trace the profile that means the stylus of the surface finish measurement instrument will should be moved on the surface to be tested you can see here we have a conical stylus and then radius tip so this radius will be like 2 micrometer or 5 micrometer or 10 micrometer and this stylus or probe tip will move on the surface now you can see this is the center of this probe curved probe and now when we move this stylus now we can see this is the locus locus of the center point this point okay now we can see the locus we have a sharp point here and here also we have a sharp point and then we have a peak here so at this place you can see instead of getting a peak we have a radius here so a sort of filtering effect will be there because of this radius of the stylus probe so we get the traced profile like this so which consists of the various elements like form, waviness, roughness etc etc that means the total profile which is a combination of form error, waviness and roughness we get and then using appropriate filters low pass filters and high pass filters different filter Gaussian filter different filters are used to get the required profile so if we pass this data obtained in this total profile via this low pass filter then we get the primary profile okay you can see here primary profile parameter so which has waviness as well as the roughness the form error has been removed and then again this data should be passed through high pass filter so that waviness can be removed and now we get the roughness profile you can see here all the waviness has been removed here only roughness parameters we get here roughness profile parameters we can obtain and if you pass this profile data primary profile data via the band pass filter then we get only waviness profile and we can eliminate the roughness parameters so the profile what we get will be something like this so its roughness element micro irregularities has been removed and we get only waviness profile parameter so like this by passing the data obtained via the various filters we can get the required parameters now how do we select the sampling length or cutoff length now you can see here we have listed different machining process milling boring turning grinding planing etc and then we have sampling length for milling we can select 0.8 millimeter sampling length or 2.5 millimeter or 8 millimeter 10 millimeter again this depends whether the milled surface is fine or very rough if the milled surface is very rough we can select the cutoff length of 2.5 or 8 if the milled surface is very fine by adjusting the fine machining parameters if we get fine finish then we can go for 0.8 millimeter cutoff length similarly we know that you can see here milling in the milling process they normally we get an RA value of 0.8 to 7 micrometer so and in the case of grinding we get very fine surface finish that is RA value of 0.025 up to 1.6 micrometer so better fine finish we get here so in the case of grinding we can select lower cutoff length like 0.25 millimeter 0.8 millimeter something like that now this is by knowing the machining process we can select appropriate sampling length or if we know roughly what is the surface finish that is obtained then also we can select the cutoff length for example if we have a surface if we know that the surface roughness on the surface under question is between 0.02 and 0.1 then we can select a finer cutoff length of 0.25 millimeter or if the surface finish is in the range of 2 to 10 micrometer then we can go for a cutoff length of 2.5 millimeter okay so by knowing approximate roughness value we can select cutoff length or by knowing the process also we can select the appropriate cutoff length now we should know one more thing that some ratio of sampling length to evaluation length now you can see here normally evaluation length is divided into 5 sampling parts or if we know the sampling length for example say 0.8 millimeter is the sampling length 5 times of this will give us the evaluation that means 0.8 into 5 that is 4 so 4 is the 4 millimeter is the evaluation length similarly if the cutoff length is 8 millimeter 5 times of this is 40 millimeter now what is the effect of cutoff length selection on surface finish measurement I can see here this is the profile obtained without any filtering and then when we select a cutoff of 0.8 millimeter okay then the finish surface finish value obtained will be 3.5 to 4.2 micrometer but instead of selecting 0.8 millimeter cutoff if we select a very finer cutoff length of 0.25 millimeter then the roughness value is 1.8 to 2.2 micrometer RA similarly if you go for very finer surface finer cutoff length then you can see here this is 0.08 millimeter cutoff is selected then the RA value obtained will be 0.95 to 1.05 micrometer that means if we change the cutoff length the RA value will also change so we should exercise a lot of care while selecting the appropriate cutoff length. If we select wrong cutoff length then the measurement data that is obtained will be useless so that is why the standards specify for the different machining process what should be the cutoff length that is to be selected or specified in various standards. Now we should understand one more thing that is distortion ratio so I can see here we have 4000 divided by 200 so 4000 is the vertical magnification so I can see here 4 parts are there this is 1 and this is second part and this is third and this is 4 part so each is having a value of 1000 so total height is 4000 units so this is the magnification 4000 times the magnification the roughness is magnified so and the horizontal magnification is 200 times now when we select this particular distortion ratio this is the profile that is obtained. Now if we change the distortion ratio then the profile the surface graph gets distorted we get another different kind of surface graph you can see here the distortion ratio is 4000 divided by 50 4000 by 50 so the vertical magnification remains same whereas horizontal magnification has been reduced by 4 times here it is for 200 units and here it is 50 units that means the length is compressed so this profile is compressed so just by observing the profile graph we cannot say so if we change the distortion ratio and the look of the profile will change we do not get similar graphs similarly we have one more example here this is the ground surface profile with distortion ratio of 10250 you can see here for milled surface okay vertical magnification that is selected is 4000 whereas the ground workpiece the magnification selected is 10000 since the surface will be very fine the very high magnification we have to select to get the profile. Now the same ground surface when we change the distortion ratio now you can see vertical magnification is the 10000 only whereas the horizontal magnification is changed to 200 then we get a profile like this and now let us study about the stylus and datum so there are two types of stylus instruments one with true datum we say skidless instrument and other with surface datum wherein some skid is provided to establish the reference reference. Now this picture shows true datum or skidless instrument I can see the probe which is moved on the surface and the datum is provided by the instrument external to the surface so the datum is not obtained by the surface itself it is provided outside so that is known as skidless instrument or true datum instrument you can see another version of true datum instrument here we have used an optical flat very flat surface is used as true datum and this is the pickup unit and this is the stylus unit and when we move the pickup you can see the stylus will move up and down depending upon the surface roughness and waviness. Now the advantage of true datum is that the resulting graph is nearly a true representation of the surface along the line showing form error waviness and roughness so it gives a total profile the disadvantage of this system is that it is very difficult to set up the instrument. Now we can see here the datum true datum height should be properly adjusted so that the it is parallel almost parallel and in line with the surface in question so very precise alignment the surface is required particularly if surface of tapered component is to be measured now you can see the mounting of tapered component when the tapered components are to be measured how do we adjust the datum in the case of true datum system so you can always use a work table with ball joint you can see here a work table with a ball joint so depending upon the taperness we can always align this we can change the inclination of this table so that the surface becomes parallel to the stylus movement or the probe movement like this so we have a tapered component like this and then we have the stylus and then externally we have the datum so the movement of the stylus should be parallel to this datum so in that case this line should be made this generator should be made parallel to this datum so in such cases we can use the work table with ball joint we can tilt the work table so that the generator becomes parallel to the movement also another provision is we can tilt the drive unit itself you can see here there is a knob here for adjusting the height of this that means to change the inclination of the movement and also there is provision for moving the total drive unit up and down for vertical height adjustment now let us conclude this lecture in this lecture we studied the various parameters which are used to specify the roughness like roughness parameters, waviness parameters and spacing parameters and also we learnt about the different methods of measurement of surface finish also we started discussion on stylus type instrument we discussed about this kid and then the stylus and then tip radius of the stylus etc now we will conclude this session in the next class we will continue with the discussion of the stylus type instruments thank you.


Hello friends, welcome back to another episode here on the channel. I hope you're all doing great and for anyone new to the channel. My name is Lee, also known as Osiris. Today, we're going to be continuing on with our VGC Series 8 content. We're actually going to be featuring a rental team. This popped up on my timeline over on Twitter yesterday from a Japanese player who'd been using this in the previous format. Obviously, the latter has just updated now. So we've gone into a new phase of Series 8, but this is what they've been using in the previous season and had a lot of success with it. I love the elements from this team, and I thought it would be a really good one for us to kick off with today. Obviously, all their socials, I'll be down in the description if you want to give them a follow going forward. Yeah, we've got the Polytoad, Kingdra, a really good dominant combination here. You kind of tend to see Kingdra and Kayog are more often in this format, but Polytoad provides that rain and the drizzly ability there and nice options with the trapping ability of Gotha Tell that we'd say a bit of a throwback from previous formats that we've had in and later years. And then you've got Mindshire, which is just there to kind of support taunt with the fake out close combat and the U-turn to give a pivot. So while it's a really boom, which helps out, especially with the rain mode benefits from the rain and then Zassian going to be your restricted Pokemon on this team. So we're featuring Zassian today. It's going to be really nice. Obviously, we featured Zamas Enter in a previous episode. So we'll play a couple of games of the team. We'll talk through it. So here's a rental code for the team and that further ado, friends. Hope you enjoyed today's episode. Leave your comments down below. Let me know what your thoughts are on this kind of build. It would be great to hear your opinions and without further ado, we're getting to our first match of the day. Okay. So up first today, we have a team of indeedy female Alolan Maruak, Cinderace, Kingdra, Togokis and Kyogre. So we've got a little bit of a rain off here. We do have ways to kind of help out our rain matchup. Obviously, Rilla Boom will help against things like Kyogre, but my opponents packed out their team with things that really help against the Rilla Boom. Obviously, the Togokis, Cinderace, the Alolan Maruak as well, all do pretty well against Rilla Boom. So we have to kind of be a little bit careful around how we utilize in the team here. I think a good way to potentially go forward is maybe go Kingdra up top. Kingdra is always going to be a good lead here because with the rain in the back potentially for ourselves, it could help us out a bunch, but it's what we bring to kind of... I mean, we can trap. We could trap as well. We could trap. There's not much speed control my opponent's team aside from airstreams. So if we can kind of keep up with the airstreams, that's always very, very useful option. I think Poly Todd in the back and then maybe we go... Do we go Poly Todd? I don't know if I'm going to go to tell actually. I think I might go Poly Todd, Rilla Boom and Zassian. I think that might be the best route for us because although my opponent might set the rain up for us, I think it's better. You know, the fact is that we've got the rain to support a Kingdra straight away. And also if they go Max Wyrmwind into Kingdra with their Kingdra, we've got a really good switch into Zassian. So it's just if we see Kyogre Kingdra from my opponent, it makes things a little bit more difficult for us, but we don't see that. We're going to see the Indidi and the Cinderace here. So this is actually alright. We don't necessarily need to Max here either because we've got the rain up. We could just go for a potential muddy water. Because that then gets around the the redirection. The problem would be is the Indidi going for an expanding force, which wouldn't be ideal. So one of the options we could potentially go for here would be go for that. Oh, we don't have muddy water. Okay. So that was one of the options that they didn't didn't want. Now do we Max and Airstream might be better going for that and getting the speed jump straight away and then getting boom on to the field. How do we just stick with with with polytod here? She said I don't really want to take an expanded force and whatever they are. Yeah, I think especially if it's not G Max Cinderace, it might be a better idea to pull the rain into the back. So at least if we see the Cinderace set the sun up, then we'd be able to we'd be able to kind of overwrite that the next time, but we're not going to be seeing that because the Kyoga makes this way into the field and it's going to eat an Airstream. It makes it very difficult for my opponent now because obviously they do have the redirection, but we do have access to fake out and we put a lot of pressure on to that Kyoga straight off the back with the really boom switching, which is always very nice. And it's all about kind of keeping that pressure on my opponent here because obviously the mirror mirrors are always difficult and you want to try and just take a little step and edge forward in the match as soon as you can and try and keep a hold of that and kind of keep the momentum going. So it's all about the position and of your Pokemon because already we can see potentially next turn, depending on the damage that we do here today indeedy. It could be in range to go down from a grass glide. Definitely not definitely not, but with the redirection we can stop that with, you know, fake out here. The Kyoga is likely to switch out into something like Cinderace maybe the next turn, but it's also a very risky thing to do because if you do that then obviously there's always a chance that we could go for like a Max Wormwind or a Max Geyser here as well. Kind of trying to think what would be the best play. Best play for us would be probably Max Geyser. I think Max Geyser and now let's go for the Max Airstream again into the Kyoga. Let's go grassy glide into the Kyoga as well. Let's try and double up into it. I think might be good. We might just see follow me. Yeah, we do, but the grassy glide plus another Airstream would be useful. Kyoga probably goes for Ice Beam here. Yeah, that definitely puts the Indeedian range now to go down to the Airstream and we've got a good speed advantage now with King Dreena in the rain with plus two. So even if the rain goes away for whatever reason, then at least we've got that as a benefit. And the fact is we've got a grassy terrain up as well. So we kind of win that terrain wall, which is always useful. Blizzard coming out. We do have the double avoid and that's always a bit unfortunate for my opponent, but it's always the risky kind of run with those lot accuracy moves, especially the spread ones where they've got the opportunity to kind of miss both targets instead of hitting. So a little bit unfortunate for my opponent as the Toa Kis comes onto the field. Now, we probably, we're in a little bit of a tricky, tricky position because you've obviously got the redirection again, which is a little tricky. So you kind of want to try and get Zassian onto the field if we can. I think it might be better going for the, do we go for a U-turn? Grassy glide. They have to go for redirection here. It's just whether or not we want to keep Boom on the field. That's the thing. Like, really, Boom is like super important to us. Whereas we could just go for a U-turn maybe into the Kyoga and then if they do redirect, then we get Boom off the field. Yeah, it's just not so safe to switch in Zassian right now because the issue is if Zassian comes onto the field, we potentially take a full power water spot, which is not something that we really want to be doing, you know, do some nice damage to the Toa Kis and we'll get the U-turn off and we'll get Poly Todd back onto the field because really with Poly Todd as well, it kind of gives you an end game situation with the Perish song, where you can whip the opponent down to two Pokemon. Now, regardless if they max later in the game, as long as Poly Todd's got the ability to kind of press that Perish song button with two Pokemon left, which will potentially in the position to do this next turn where we can hurricane into the Kyoga and scald into the Toa Kis. We should be able to pick up the knockout or we could just double tap into the Toa Kis slot because Cinderace is going to come in on that slot and it's not really going to want to take the double up. I mean, in hindsight, we're really better going for the hurricane into the Kyoga just to get damage onto it and then scald into the Toa Kis with Poly Todd, which will be enough to take it out. And like I say, if we see the Cinderace come in there like we're seeing now, we're going to be able to probably pick up the knockout onto it with the scald in the rain. So we're going to see a protect from the Kyoga. Is the Toa Kis going to come? Wait there, sorry. What am I saying? If this picks up the knockout, that's ideal. That's what we want. Yeah. Okay. So that's perfect. And now all we need to do is click the perish song button and play around their Dynamax turns. Now, you've got to imagine that the Kyoga is going to be the Pokemon that Dynamax is. But without the electric terrain up with the Wackenberry on the Poly Todd, there's no way other than a potential flinch that's going to stop the Poly Todd getting the perish up and that kind of locks the game for us. So that's what I'm trying to say to you all. Like you've got the option there of a really nice wind con. We'll go for the hydropump into the Toa Kis. We've got the speed advantage and we'll just click perish just to lock this one up because with the Pokemon that we've got remaining, there's no way that we can't switch around or just stall out between protects with what we've got in the field, which will allow us to get the most out of this opportunity. So there's a hydropump we do hit and the Toa Kis going down and Kyoga are going to be the last Pokemon standing. But again, we still got Rillaboom in the back to come in. So we don't even need to wait these three turns if Kingdra drops here for whatever reason. And we're not seeing my opponent actually click that Dynamics button just yet. We might see the forfeit come out this next turn just with the perish song kind of locking things up for us here. We also have like we could just sit here with Kingdra as well and just chuck attacks out until we're kind of happy for them just to go down and whatever we've got in the back to come in. You know, we don't need to take any risks at all at this point. We've got it locked up. If these two go down here, then you know, it doesn't matter to us because we still got two Pokemon in the back, grassy terrain going away. And we can just chuck out. I think just some Draco meteors now with the fairy redirection off the field. We're pretty safe to just launch that and see if we can pick up a cheeky skull along the way with Polytod because we're just wasting time now unless we see the forfeit, which I think we might do. I know we're not. My opponent's playing it out. So fair enough to them as you get the Draco on to the Kyogre.  It does so much damage with the life hold, doesn't it? It's such a great attack. It really is. And we'll see the thunder coming out now, but it is going to just activate that Wackenberry that we do have on the Polytod. Obviously reducing the damage there, which is always very useful, especially in a format where you've got quite a lot of electric type users. And we don't have any redirection like Lightning Rod or anything like that on the team, which could kind of help with that. And we do get the burn as well. So everything that we're asking for in this game is kind of playing out, which is great. So the Kyogre likely to go down this next turn. We'll just help in hand and go for a Draco meteor. And it should be enough to get the win, get the W for us today, so which is always good. And I do love helping hand on Polytod as well. It is such a nice option. Especially, I think that just set in general, just it's got such utility, you know, the helping hand, the perish and the Skald. It gives you so many options with how useful Polytod can be in there. There we go. Fair play to my opponent. You'd see a lot of people kind of forfeit in those situations. And you can see why there's not a lot coming back, but you know, sometimes taking note, playing till the end, it's worth doing. You never know what's going to happen in a battle. But very good game to my opponent. A nice one for us to kick off with today. And we'll jump into our next game of the episode. Up next, we've got Sammy playing a team of Grimsnall, Incinero, Garchomp, Kyogre, Tepacoco and Metagross. Really cool looking team for us to kind of go up against this next game. Love seeing the Garchomp and the Metagross. Real throwbacks to previous formats. And it's quite a nice looking team. You've got the Kyogre, which is going to be the kind of centerpiece of the team with the fake out support from the Incinero. Intimidate there. The screen support from the Grimsnall. Potentially, I'd say maybe some speed control from the Grimsnall. It does get scary face. It does get thunder waves. So their options there, the Tepacoco. Again, going to be something that can threaten us. Obviously with its electric terrain as well. Going to have electro wet. A lot of kind of utility moves to support and be threatening at the same time. So not something to kind of underestimate. Metagross, what are we going to see? Like bulldoze from potentially something like the Garchomp. I guess does Tepacoco get brutal swing? I wouldn't have thought so. But maybe there is the option there. Metagross going to be something that we need to kind of watch out for definitely in this match. So what are we going to do? I mean, we could lead Gotha Tell. It gives us a nice opportunity. Problem is leading Goth is I mean, we could go down a parish trap route here. The thing that I would say is we're probably going to see Tepacoco come out, you know, from my opponent. But we could go Polly Todd, Kingdra, and I think Zassian. We'll go from maybe more of a parish trap kind of. Um, no, we're not even going. What are we leading with Gotha Tell? Gotha Tell Polly, Kingdra and now Rilla Boom Polly. That's what we're leading with. So we're leaving the Gotha Tell on the bench, but I think it makes more sense to bring the Rilla Boom is what I'm meaning really. It'd be nice to get the parish song off first, but we'll see what my opponent goes for. Bringing the Metagross in. We need to get Kingdra on the field as soon as possible. Really, that's the that's the big thing here for us. We do have knockoff with Rilla Boom, but if there is a weakness policy on the Metagross, obviously we will proc that straight away.  That's going to be super useful if we can, if we can kind of get that as soon as possible. Now, it might be a good idea to get Zassian onto the field in all honesty, because if we get the Zassian onto the field, it's likely that the Metagross, if it does attack, it goes for either a Steel Spike or a Max Hailstone. And if we do see a Max, may not Max, but I don't see it going after the Politoad. We are going to see that. It's not going to go for a Max Quake, which is kind of the big option. I mean, they might, they might boost the special defense here just to kind of give them a bit more longevity against the Politoad and potentially when Kingdra hits the field later on. But I think the big thing for us here to do is try and stall out these Dynamics turns with the Metagross because the screens are going to go, ooh, Thunder Wave coming out. That's, that's not so good. That's not so good. So there's the, yeah, that's the speed control and it's going to make utilizing Zassian very difficult, really difficult as we do see the Zassian kind of take that pretty well. But we need a Skald burn. Polly's quite good at that, but we're not going to get at this turn this time around. We're not getting it. We are going to see the Grimstone go for the Thunder Wave again. It kind of ties it up though. It ties it up from using the screen support, which is always useful. And I'm just thinking now, do we switch in Rillaboom now? Or do we just protect? I think we protect with Zassian this turn and then we go for another Skald. We just try and get those burns because that's the big thing. Like if we can prevent the Metagross from boosting up, it is probably going to go from the Max Quake here, which is not ideal because of the special defense boost. Obviously, we kind of want to try and mitigate that, but at the same time, we're not really going to be able to stop it any other way. But we definitely don't want Zassian getting paralyzed. That's the thing. I think, oh my steel spike. Okay, boosting the defenses. I prefer to see that all day long. All day long, honestly. I know I haven't got the rain boost anymore, but if we can get the Skald burn here, this is what we're kind of aiming for. Poly's just good.  Don't get it again. So, you know, out of three, you should get it. 30% chance to burn. Not guaranteed, of course, but you should be able to get it. Now, Zassian, do we want you paralyzed? I don't think so. I think we need Zassian kind of fighting fit for later in this game. The other option here is, do we start going after the Grim Snow? I don't think we change our minds right now, but from the get-go, if we start Skalding there, it might have been an option. You know, I'm hoping that we're going to see the Max Quake come out now from the Metagross, and then we'll pull in, pull in Rilla. So, let's see, because we are going to get paralyzed, unfortunately, but it's better Rilla Boom getting paralyzed than Zassian. We're going to see Reflect. Okay. Better than that T-Wave. Could have got a sub up here. Oh, Max Knuckle. Okay, wow. And that's into the Toad. So, they are boosting their attack, and they do get the critical hit. You know, did way more damage than what I thought it was going to do, which is a little bit of a shame. But we just need this burn. We just need the burn. That's all we need. A bit of luck. Third time, we should get it, but we don't get it. Three out of three, we do not get it, which is super frustrating for us in all honesty. We need to try and get the rain back up as well. So, we've got to keep that in mind with Poly Toad. Like, do we get the rain back up as soon as we can? I think the next turn, we could potentially perish. Fake out the Metagross Parish song. It'll be a bad option. Because then it means my opponent has to start switching around at some point. You know, they can't really just leave things on the field. And we're going to be switching these two Pokemon out for sure anyway. Metagross just going for that protect, which is fine. So, I feel like the Metagross against this team is pretty difficult, because it makes it difficult to bring Kingdra when you've got something like... when you've got Grimstone sitting in front of you. But we do get the Parish song off, which is useful. And like I say, we can kind of switch things around going forward. I think we U-turn out onto the Metagross. Just get to... Maybe U-turn out onto the Grimstone as well. Could be an option. We just need to get damage onto the Grimstone in all honesty. And the grassy terrain going to actually kind of disappear soon. So, or is this the right time to switch Poly Toad off the field? Potentially. I mean a grassy glide and a Skald, and a grassy glide and a Skald should get the Grimstone. You know? So, I think we'll go for that this turn. Because it's not likely that Rillaboom goes down to double attacks. Wow. We've said that now. Geez. Okay, well we're paralyzed. It's not so good. And then Ice Punch coming out. Okay. Skald. Do they have Spirit Break then? Because that would be the thing that would worry me. I can't believe we've got like literally no... like literally no... no burns. Four Skalds, no burns. That's bad RNG for you right there. They may not have Spirit Break. They've got Reflect. They've probably got Light Screen. They've got Sucker Punch and they've got T-Wave. The board position that we kind of need to get is Poly Toad. Wow, we need... we need Kingdra next to Rillaboom. That's what we need. Alright, I'm going to pull Insass in there and I'm going to pull in Kingdra here. And then we can get Poly Toad onto the field. Protect Kingdra, get Rillaboom on, and then nuke the Grim Snow. But the thing is like as well you've got to think like we could utilize our Parish Song Turns where my opponent either is forced to switch out on that final turn which doesn't allow them to get the T-Wave or the Stain and we get the Fake Out and a big attack into them. But we're only going to get one opportunity to do that. It's just avoiding the Thunder Waves. It's such an overlooked utility, you know, but it's such a really good utility at the same time. Okay, Papa Coco coming in, which is alright. Alright, our Terrain, but we are pulling the Double Switch. So it's likely we only take maybe an Ice Punch into Zass in here which is actually not too bad and it does give us the opportunity to avoid any Thunder Wave kind of shenanigans as well because I think we pull Zassian out the next turn. Get Poly Tour onto the field, Max Geyser into the Cocoa. Okay, Bullet Punch. I mean we take that pretty comfortably. Metagross has to switch out this next turn as well which is the big thing. So get Poly onto the field and we'll go for a Max Geyser into Cocoa. And we'll see if we can start kind of cutting through my opponent's team now because that's the big thing. I'd imagine Grim Snow to come back onto the field where the Metagross is. We could have potentially stayed in like we are now and went for Behemoth Blade into that Metagross slot because they've got to switch it out. I don't see them sticking in yet. They're not going to stick around with it. It doesn't make sense. Grim Snow is going to come back in, yeah. So it means we're probably going to have to protect one turn if we want to avoid the Thunder Wave. That's really annoying. Grim Snow is just one of those Pokemon and it's like you need like double fake out support to get around it but then it complicates things with needing to rain up and stuff like that. It's tricky. Well, we've got the rain up now. We've got the Max Geyser coming out into the Cocoa. Just take it down, yep.  It's just risky because, hmm, yeah. I think we need Rillaboom as well. We need Rillaboom so we might be better just doing this because then we got Metagross to come in in the back. Kingdra should still outspeed the majority of stuff. Yeah, let's go Geyser into Grim Snow. It's just whether or not they got... We don't get the help in hand boost. We really needed the help in hand boost there. The paralysis really biting us. She's not good because there's the T-Wave coming out and she's not ideal. Just going to hope that the Geyser is enough to pick up the Grim Snow without the help in hand boost. You've got to hope it is. It's not. It's not. Oh, it's not. It's not. It's not. It's so frustrating. It really is frustrating. Really frustrating. Okay. Let's try and get a Perish song up if we can and let's go for a Max Airstream into Grim Snow at least then as long as the rain's on the field. We'll get the jump on the Kyogre which is always going to be useful. We'll get the jump on the Metagross as well just to ensure that if we just got the help in hand boost this is where the T-Wave paralysis comes in. Super frustrating and it's something that you just don't see many players really taking advantage of. I know there's a lot in the format that you can't Thunder Wave because of obviously resistances, Lightning Road and other things but I mean one of the key things you think about your opponent really utilizing is the fact that they've got the speed advantage most of the time. Max Airstream is one of the most dominant Max moves because of the advantage it gives you over your opponent. So T-Wave being such a free move to just throw out and be so disruptive as we've seen in this match it makes it difficult doesn't it to really kind of get the most out of your team when you've got that kind of thorn stopping you most of the time. So Metagross is going to come in. I think Rillaboom coming in now. Gracie Glide, they've got Zasin to kind of fall back on. Just need to remove the Metagross from the field. That's the big thing for us. So if we can hit a Gracie Glide into the Kyogre pretty much takes it out of the game really you know. Hydro Pump going to be enough to take down the Metagross as well so that's fine. They do have Bullet Punch of course but I don't know if a Bullet Punch is going to be enough to get the Rillaboom from the range that we're in and we also have Fake Out as well so that's something else that we've got. Bullet Punch might be enough you know. Bullet Punch might be enough to get, to get it. We'll go for a Gracie Glide. We could double up into the Metagross and hope that the Kyogre protects because then, no, no, I don't think so. I don't think Bullet Punch is going to get us. I'm going to go on a whim and say Bullet Punch is not going to be enough. Metagross Protecting. Okay, does Kyogre Protect as well just to stall out the Fake Out? No, they don't. Okay, not the best idea because now that just locks it up for us. I think when you've got access to Bullet Punch you've got to go for it there. You've got to go for it there even if the Fake Out comes out because if we don't go for Gracie Glide and Fake Out it means your Kyogre is safe. But if we click the Gracie Glide button you've got to go for the Bullet Punch and hope that it's enough to take us up from this range. Like I say, I think we might have just hung on but who knows, the Metagross might have had enough to do it. We'll go for a knockoff because I think we're fine now with the fact that Kingdra's faster than it. We've got Zassian in the back to come in as well and kind of just finish off things if we need it to and pick up the knockout with the Hydro Pump. So there we go. Kingdra putting in some work in both games today. Not really seeing too much of the Zassian but it's always there to be a Pokemon to come in and help sweep up if we need it to. Very good game to my opponent. We've had two good games and we'll hop over now just to remind you all of that rental code for today's team and again, a big shout out to Apoona Capona. I think that's the username. So we'll be right back with the rental code. Okay friends, here is the rental code for today's team. Like I said, it is going to be a rental from another player that we're using today but it's been a very exciting team to kind of feature him a little bit sad. We didn't get to see the mind shell but we've got to see the rest of the team a lot and obviously the ally switch there we didn't get to use which is always very sad. But if you do try this team out definitely have a lot of fun with it. I think it's a nice concept to take on the ladder and try out. I think it's a really strong build and again, big shout out to Apoona Capona. Apoona Capona. I don't know if I'm pronouncing that right. Probably not, but anyway, their links, their social handles are down in the description if you want to check them out and have fun with the team. We'll be back later in the week but just to reiterate, if you've got rental teams you'd like to feature, see featured on the channel. Let me know down in the comment section send your rental codes over and I will feature them as we go through the next couple of weeks. We're going to be jumping back on the Twitch and streaming over on YouTube. So keep an eye out for that. We'll be streaming over on Twitch tomorrow night which would be a lot of fun. So come and join us and we'll be streaming later in the week here on YouTube. So keep an eye out for that friends. Have a great rest of your day. What are you up to? And thank you so much for tuning in as always. Hope you've enjoyed today's episode. Until next time, see you later. Bye-bye.


U.S. Army sets up first permanent garrison in Poland. The U.S. Army has set up its first permanent garrison in Poland, Polish Defense Minister Mariusz Blaszczak said at a ceremony at Kamp Kosiusko in the city of Poznan. We have been striving for this for years, for this word permanent and it has now become fact, said Polish Defense Minister Mariusz Blaszczak at the opening ceremony. While Poland has long hosted U.S. troops on a rotational basis, it had lobbied Washington for that to be turned into a permanent presence. This is a historic moment, a sign that the United States is committed to Poland and NATO and that we are united in the face of Russian aggression, declared Blaszczak. It is the 8th garrison of the U.S. land forces in Europe with the others located in Germany, Belgium and Italy. Blaszczak, addressing the U.S. troops present, said that he was proud that Polish soldiers can exercise and increase interoperability with you. In the situation that Europe finds itself in, when Russia has invaded Ukraine, when Russia is trying to rebuild an empire, it is very important that the Western world is united and that it feels safe, he added, and it feels safe when our armed forces are working together. The U.S. Ambassador to Poland Mark Brzezinski declared that the inauguration of the garrison was a sign that the United States is committed to Poland and the NATO alliance and that we are united in the face of Russian aggression. In recent years, the already close military cooperation between Poland and the U.S. has been further strengthened with Washington sending additional troops and equipment to Poland in response to Russian aggression. Currently around 10,000 U.S. troops are stationed in Poland.
