特种加工作为先进制造技术中的重要组成部分,对制造业的作用日益重要。特种加工方法就是将电、磁、声、光、化学等能量或其组合施加在工件的被加工部位上,从而实现材料被去除、变形、改变性能或被镀覆等的加工方法。特种加工具有区别于传统机械加工方法的一些特点;特种加工有多种加工方法;特种加工对机械制造及结构工艺性具有重大影响。 As an important part of advanced manufacturing technology, special processing plays an increasingly important role in the manufacturing industry. Special processing method is to apply electricity, magnetism, sound, light, chemistry and other energy or a combination thereof on the processed part of the workpiece to realize the processing method of removing, deforming, changing the performance or plating the material. Special processing is different from the traditional mechanical processing methods of some of the features; special processing a variety of processing methods; special processing on the mechanical manufacturing and structural process has a significant impact.
