一、引言本文初步试用声技术研究放电加工机理。为此直接测量了伴随放电过程的声压,并将录制的声波形,对照其相应的极间电压信号及试样工艺效果同时进行分析研究。通过大量单发脉冲和重复脉冲放电实验,进一步探讨了火花放电、过渡放电、电弧放电三种主要形式放电的机理、形成条件和工艺效果。并引伸出用强化等离子放电通道的振荡,可以提高生产率、改善加工表面质量的理由。
I. INTRODUCTION In this paper, we try the acoustic technology to study the EDM mechanism. For this reason, the sound pressure accompanying the discharge process is directly measured, and the recorded sound waveform is analyzed at the same time against the corresponding inter-electrode voltage signal and the sample process effect. Through a large number of single-pulse and repeated pulse discharge experiments, the mechanism of spark discharge, transitional discharge, and arc discharge were further discussed. The formation conditions and process effects were also discussed. And leads to the use of enhanced plasma discharge channel oscillation, can improve productivity and improve the quality of the surface processing reasons.
