影响电火花加工性能指标的因素很多。利用单板微型计算机对一些参数实现优选，而对另一些参数进行在线的自适应调节，可以使系统在满足加工表面粗糙度、加工精度和工具电极相对损耗及不发生电弧放电的条件下获得最高的加工速度。从而最大限度地发挥电火花加工方法和设备的作用，对现有的配有晶体管脉冲电源的机床，只要增加简单的接口，便可实现微型机对加工过程的控制。 Many factors affect the EDM performance index. The use of veneer microcomputers for optimization of some parameters, while the other parameters of online adaptive adjustment, can make the system to meet the machining surface roughness, machining accuracy and tool electrode relative loss and the highest arc without the highest access conditions Processing speed. To maximize the role of EDM methods and equipment, the existing machine equipped with a transistor pulse power, as long as the addition of a simple interface, you can achieve micro-machining process control.
