一、前言目前数控线切割机床已广泛地应用于模具加工。然而,其大多数的数控台是采用专用数控装置(称为硬件数控),若要改变或增加控制功能,就必须重新进行逻辑设计、印刷板和框架的设计制造等工作,这样,不仅设计、试制周期较长,而且,制造时还需要有一个熟悉、掌握它的过程,从而也影响了数控装置的可靠性。近年来,随着大规模集成半导体加工工艺的飞速发展,微处理器已开始应用于机床的控 First, the foreword At present CNC WEDM has been widely used in mold processing. However, most of its numerical control stations use a dedicated numerical control device (called hardware numerical control). If it is necessary to change or add control functions, it is necessary to re-design the logic design, the design and manufacture of the printing plate and the frame, so that not only the design, Trial cycle longer, but also need to have a familiar manufacturing process to master it, which also affected the reliability of CNC equipment. In recent years, with the rapid development of large-scale integrated semiconductor processing technology, microprocessors have begun to be used in machine tool control
