Material removal from ductile matesials can be accomplished by using a tool which is harder than the workpiece.However during World War the widespread use of materials which were as hard or harder than cutting tools created a demand for new material-removal methods.Since then a number of processes have been developed which,although relatively slow and costly,can effectively remove excess material in a precise and repeatable fashion.There are two types of processes.The first type is based on electrical phenomena and is used primarily for hard materials; the second depends upon chemical dissolution.

用比工件硬度大的设备可以实现从韧性材料上去除材料.可是在世界大战期间由于和切割设备同等硬度甚至更硬的材料的广泛使用,对于新的去除物料的方法的需求便产生了.从那时起许多的加工(方法)得到了发展,虽然相对来说慢而且费用高,但是可以以一种精确而且可重复的方式有效的去除多余的材料.有两种加工(方法).第一种基于电现象,另一种主要用于硬度大的材料.第二种依靠化学溶解.
