五十年代末所进行的工作表明,利用材料电火花加工方法来精密加工(具有较高表面光洁度和有足够的生产率)任何导电材料的小型和复杂形状零件的可能性是很大的。目前,由于制品的小型化和对其质量和加工精度要求的不断提高,材料电火花精密加工在工业中的应用越来越广泛。为了揭示电火花精密加工的基本特徵,我们探讨如下几个关系: 1、在微秒时间的火花放电作用下,电极上所形成的凹坑的几何尺寸与放电能量之间
The work done in the late 1950s showed that the possibility of using precision machining of small and complex shaped parts of any conductive material (with high surface finish and sufficient productivity) using material-to-electric machining is very high. At present, due to the miniaturization of products and the increasing demands on the quality and processing precision, EDM precision machining of materials is more and more widely used in industry. In order to reveal the basic characteristics of EDM precision processing, we explore the following relationships: 1, in the microsecond spark discharge time, the electrode formed on the geometry of the pit and discharge energy between
