| Abstract: | In order to master the law of short electric arc machining (SEAM) technology,the machining effect of that should be controlled as much as possible,to achieve the goal of high efficiency and low loss, W-Cu and graphite were selected as tool electrodes based on systematic process experimental research. The short electric arc milling process tests of different electrode material on the influence rules of working medium injection,erosion removal and power utilization rate were carried out.The influence rules of various process parameters on evaluation indexes such as MRR,TWR,micromorphology and metallographic structure were obtained in the experiment,and the causes of the process rules were further explained to give full play to the advantages of hard alloy high-efficiency machined by SEAM. |
