The APT system converts APT language statements to signal codes for automatically directing an NC machine, and provides a vocabulary for geometric definitions of parts, tool motion statements, auxiliary function commands, and system commands to enlist computer assistance in formulating part programs. The conversion is effected through the primary functions of language translation, geometric processing, cutter motion calculations, and postprocessing for adaption of general solutions to particular NC machines.
Future developments include language of higher abstraction levels, on-line keyboard and graphics, and compatibility with computer aided design and analyses. Past APT developments will be made available to industry generally.
