DESIGN FOR MANUFACTURABILITY Design for manufacturability (DFM) is the process of proactively designing products to (1) optimize all the manufacturing functions: fabrication, assembly, test, procurement, shipping, delivery, service, and repair, and (2) assure the best cost, quality, reliability, regulatory compliance, safety, time-to-market, and customer satisfaction.

Introduction to Modulation Transfer Function When optical designers attempt to compare the performance of optical systems, a commonly used measure is the modulation transfer function (MTF). MTF is used for components as simple as a spherical singlet lens to those as complex as a multi-element telecentric imaging lens assembly.

- Tuned Mass Dampers Tuned mass dampers (TMDs) work by fastening a mass-block to a structural component (such as a floor) via a spring (Fig. 3). This system is set up so that, when the floor vibrates at a resonant frequency (which could be caused by dancing, for example), it induces analogous movement of the mass Fig. 5.

- Thermally Fused Melamine, sometimes referred to as TFM or Low Pressure Laminate, is the product made when decorative (printed) papers that have been saturated with melamine resins are (thermally) bonded/fused to a substrate (Particleboard, MDF) using a combination of pressure and temperature.uring the manufacturing process of the overlay, the decorative paper is saturated with a resin but it is not fully cured — it is “B-Stated.” If properly stored, the decorative overlay has a substantial shelf life and will still “flow” and bond to the substrate once under heat and pressure.

What's the difference between CFM and SCFM on an air compressor? Rating Newest Oldest. Best Answer: there is a difference.. Standard cubic feet per minute (SCFM) is a volumetric flow-rate corrected to a set of standardized conditions of pressure, temperature, and relative humidity. The standard conditions are often defined as 14.7 psia, temperature 60°F and relative humidity 0%, but the conditions may vary depends on the standard used.

Pregnancy Hormones Pregnancy Hormones. Introduction. A number of hormones are necessary for normal pregnancy to be maintained until parturition. These hormones are important in terms of maintaining a suitable environment and sufficient nutrition for the developing fetus, as well as during the processes of parturition and lactation.

- ABSTRACT FSM-the Field Signature Method-is a relatively new method for continuous monitoring of corrosion attacks and cracking of pipes, pressurized vessels and storages tanks. The method is now beeing developed for monitoring of stress corrosion cracking of welds in ammonia storage tanks. NH 3 -SCC is a corrosion mechanism consisting of an anode (metal dissolving) and a cathode (oxygen reduction) reaction. This reaction is not the same as hydrogen cracking. • Initiation and propagation of NH 3 -SCC requires liquid ammonia, oxygen and tensile stress.

Interview Questions on CMMI with Answers Staged models in CMMI, specialize in method improvement, mistreatment stages or maturity levels. In staged illustration every method space has one specific goal. In software engineering, Staged models in CMMI is used to define an improvement path for an organisation using different set of predefined process areas. It has five maturity levels. Continuous model in CMMI follow a suggested order for approaching method improvement at intervals every such method space.

CFD in buildings (December 2012). CFD stands for computational fluid dynamics (and heat transfer). As per this technique, the governing differential equations of a flow system or thermal system are known in the form of Navier–Stokes equations, thermal energy equation and species equation with an appropriate equation of state.n order to reduce heat losses from buildings, CFD analysis can be done for the optimum configuration of composite walls, roof and floor. The differential form of the general transport equation is as follows.

PFMEA PFMEA (Process Failure Mode and Effects Analysis) is a structured approach that assigns quality risk levels to each step in a process (manufacturing or transactional). PFMEA is a powerful prevention tool, since it does not wait for defects to occur, but rather anticipates them and implements countermeasures ahead of time.
