摘要
以研磨法加工的微细KG5碳化钨电极为研究对象,通过试验研究放电参数对电极损耗的影响,通过改变电压、电流、脉冲和脉间参数,探讨电极损耗大小、加工深度和加工效果。结果表明,降低电压和电流、提高脉冲和脉间能减少电极损耗,但是会影响加工时长和加工效果。综合分析,电压为160V、电流1.5A、脉冲3μs、脉间2μs为最佳组合,可以实现较低电极损耗,获得较好的加工效果。
After grinding,KG5 tungsten carbide electrode is taken as the research object,and the influence of discharge parameters on ectrode loss is studied.W hen the voltage,current,pulse and pulse to pulse are changed,the electrode loss,machining depth and machining effect are discussed.The results show that the electrode loss can be reduced by reducing the voltage and current and increasing the pulse and pulse to pulse,but the processing time and effect will be affcted.Comprehensive analysis shows that the best combination is voltage 160V,current 1.5A,pulse 3μs and pulse to pulse 2μs,which can reduce electrode loss and achieve good machining effect.
