钛合金TC4放电加工电极损耗研究
Research on Tool Wear of Titanium Alloy (TC4) by EDM
摘要
Abstract
This paper uses distilled water and keroseme as dielectries to make experiments on titanium alloy (TC4) electro-discharge machining for the problems of its large tool wear, compares and analyzes two dielectrics' differences about tool absolute and relative wear and then researches on the tool wear, mechanism of titanium alloy by EDM from machining wave form and the tool's surface micro-morphology. The results show that using the distilled water as dielectric, the working efficiency is greatly enhanced, because the insulativity of distilled water is poor, but the abilities of flow and cooling are good, so that it makes the deionization full and interelectrode status ameliorated. In addition, a little of titanium dioxide produced by machining and ablation products splashed from workpiece are adhering to the surface of electrode. It is effective to restrain the tool wear. Therefore, compared with kerosene, the tool absolute wear is similar, but its relative wear is much lower in distilled water.关键词
