短电弧加工放电过程的试验性研究

The pilot study of short arc processing discharge process

对短电弧加工放电过程中放电通道的形成、工件材料的蚀除,以及工具电极的损耗等相关理论进行简述。为了对短电弧加工机理进行研究,通过高速摄像机拍摄实验,详细地观察了放电过程的每个阶段。分析最具代表性的图片并根据高速摄像机自身的相关参数设置,计算出有关短电弧加工过程中的特征参数,如放电间隙、放电时间等,对短电弧加工技术中材料去除机理的进一步研究有一定参考意义。

Describes the theory of short arc processing discharge process which is including discharge channel formation, erosion of the workpiece material, tool electrode wear. In order to achieve the research of short arc processing mechanism from theory to the purpose of checking the test data, use the shooting experiments of the high-speed camera and observe the each stage of dis- charge process in detail. Analysis of the most representative picture and according to setting the relevant parameters of the high- speed camera, calculating the characteristic parameters for short arc processing, such as discharge gap, discharge time, etc. It has certain reference value in the in-depth study of the material removal mechanism of short arc processing.
