Study on the Experimental of the Electrical Discharge Machining Titanium Alloy on Gas Dielectric

摘要

In order to know the processing properties of the Electrical Discharge Machining titanium alloy on gas dielectric. Firstly, this paper does comparing experiment of EDM in gas processing titanium alloy. The results indicate that electrode dissipation is low with equifrequence square wave, positive polarity and low supply voltage to machining titanium alloy when pulse width is narrow. Secondly, this paper has done the orthogonal experiment and the variance analysis of experimental results, Its result shows that pulse width and peak current have a great influence on the machining efficiency.
