Development of a PC-based computer numerical control drilling machine

Abstract In the research reported in this article, the personal computer (PC) is used as a separate, front-end interface for a customized machine control unit, which controls a drilling machine through actuation devices. Both the customized machine control unit and the drilling machine were built in-house. The PC-based computer numerical control drilling machine comprises several integrated technologies, ranging from a neuro-TSP (travelling salesman problem)-based optimizer for finding the best sequence of points to be drilled, a customized machine control unit and enhanced parallel port for communication to the drilling machine. Work is continuing to carry out experimental tests on the part produced by the machine and to compare the quality of such parts with those produced by similar machines.
