Abstract
In response to the chip removal problem faced by traditional electric discharge machining of metal based composite materials,by optimizing the electrode geometry parameters and controlling the tool electrode loss while obtaining sufficient chip removal space,it is proposed to use V-groove multi-channel electrodes for machining.The research results show that compared with traditional cylindrical multi-channel electrodes,V-groove multi-channel electrodes exhibit better machining efficiency,better resistance to electrical corrosion,and surface quality during machining:the average depth of small holes machined with V-groove multi-channel electrodes is increased by 7.61%,while the average electrode loss is reduced by 37.01%.The pulse width has the most significant impact on the processing depth of V-groove multi-channel electrodes,with an average increase of 12.12%in processing depth under this factor.The pulse stop has the most significant effect on reducing the loss of V-groove multi-channel electrodes,with an average reduction of 39.45%under this factor.Under the same processing conditions,compared to cylindrical multi-channel electrodes,V-groove multi-channel electrodes have smaller roughness,with a minimum roughness of 5.867 μm.The surface quality of the hole after processing the V-groove multi-channel electrode is better,and the surface morphology of the electrode after processing is better.EDS analysis shows that the electrode element content at the bottom of the hole tool and the workpiece element content on the electrode surface are lower.关键词
