Process on Single Channel Scanning Milling of Micro-electrical Discharge Based on Integration Mechanism

摘要

During the process of three-dimensional scanning milling of micro-electrical discharge, both positive and negative poles usually present as arc shape. This phenomena is called "arc shape phenomena" in this paper. This paper is to introduce erosion mechanism of electrical pulse discharged on both Typically, the hollow electrode is applied to modeling and simulation. And then real experiments will be conducted. There are two conditions for the electrode in the analysis and tests: rotating at 300 rpm and 0 rpm. Finally, the profiles of tool electrode and workpiece are provided. Results show that there are different erosion effects on both poles. It shows that the process parameters have a significant influence on the final machining results.
