一、前言随着四化建设的发展,复杂模具和精密零件加工与日俱增。数控机床的出现解决了难度大、精度要求高、批量小的零件加工问题。但人工编程是一项繁琐的劳动,与加工时间之比一般为10比1,而且容易出差错。因此它的局限性限制了数控线切割机床的推广和使用。为提高机床的利用率及其经济效益,使工件编程这一重复性脑力劳动由计算
I. Introduction With the development of the four modernizations, the processing of complex molds and precision parts is increasing day by day. The emergence of CNC machine tools to solve the difficult, high precision, small quantities of parts processing problems. However, manual programming is a tedious task, with the ratio of processing time is generally 10 to 1, and prone to error. Therefore, its limitations limit the promotion of CNC wire cutting machine and use. In order to improve the utilization of the machine tool and its economic benefits, the repetitive mental workload of workpiece programming is calculated
