一、前言电加工机床的数控化,不仅实现了自动加工所期望的高精度轮廓,而且改善了历来电加工的不足之处(由于电极部分损耗,产生间隙不均匀、波纹和锥度),还不同程度地提高了加工速度。在介绍最近动向之前,先展示一下电加工机床数控化带来的进步。图1和图2分别为近几年来NC型电火花加工和线切割电加工的发展情况。 I. INTRODUCTION The numerical control of electric machining machine tools not only realizes the high-precision contouring expected from automatic machining, but also improves the shortcomings of previous machining (due to partial electrode wear, unevenness of gaps, ripples and taper) and different Degree of increase in processing speed. Before introducing the recent trends, we will show you some advances in CNC machining of electrical machines. Figure 1 and Figure 2, respectively, in recent years NC EDM and wire EDM development.
