초록

We developed a model of NC controller with IBM-PC as a host cpu and integlligent NC servo controller for 2 axes that can be expaned to 4 axes. Basic conceptions, including hardware structure design, servo controller design, communication protocol, and interpolation hardware design was already publicated on '87 KIEE conference. Following this, we focussed on the emulation of tyhe controller with X-Y table as complete NC machine experimenting some drawings made by NC code program that can be edited and executed in automatic on single step mode. In addition we designed the M.S.T functions with PLC and tested for M-function timing. Finally, we designed NC interface to fit with M-function output and we contructed total system of NC controller with IBM PC host with the result of successful development of new NC model.
