Method of and apparatus for finely machining a workpiece with numerical control having a computer-aided simulated function

摘要

A machining program is prepared based on design data obtained by CAD and machining conditions stored in advance in a data base, while machining status information is obtained from a machining site. Based on the machining program and the machining status information, a machining status is simulated in order to subsequently prepare machining commands required for appropriate NC control.
