电火花加工自四十年代发明以来,已有三十多年历史。电火花加工的发展十分迅速,应用范围不断扩大,技术装备也日臻完善,成了现代生产上重要的加工技术。与此同时,电火花加工物理本质的理论研究也获得了相应的发展。人们利用诸如高速摄影、X光脉冲摄影、电子显微镜、扫描电子显微镜、干涉显微镜、金相显微镜、X光结构分析仪、腐蚀痕迹仪、热量分布测量仪、压力测定仪等各种测量仪器和实验手段对电火花加工物理本质进行了多方面的研究,积累了大量的实验数据和理论依据。提出了物理过程的基本规律和定性理论,对电火花加工的
EDM has been in existence for more than 30 years since its invention in the forties. The development of EDM is very rapid, expanding the scope of application, technical equipment is also improving, has become an important modern processing technology. At the same time, the theoretical study of the physical nature of EDM has also been the corresponding development. People use a variety of measuring instruments and experiments such as high-speed photography, X-ray pulsed photography, electron microscopes, scanning electron microscopes, interference microscopes, metallographic microscopes, X-ray structure analyzers, corrosion tracers, calorimetry testers, Means of EDM physical nature of a multi-faceted research, has accumulated a large number of experimental data and theoretical basis. Put forward the basic rules of the physical process and the qualitative theory of EDM
