This technology was developed by John Parsons and Frank Stulen. APT was a language for controlling  these systems. They can be controlled by G codes. The degree to which these systems can move determines  whether they are point to point, contouring, or straight cut. This system is composed of a MCU, a part program,  and processing equipment. Machining Centers are machines based on this technology that can change their own  parts. CAM is a form of this using more modern computers and electronics. Nowadays, such systems can take in  designs generated by CAD. For 10 points, name these systems for directing factory machines using alphanumeric  coding.
