电解电火花加工树脂材料的实验研究

摘要

The experimental study on phenolic resin by electrochemical discharge machining is presented.The effects of electrolyte concentration,voltage and the pressure between the tool electrode and the workpiece on machining rate are discussed.The experiments results indicate that the three factors mentioned all have positive effects on machining rate.Based on the experiment phenomenon and combining with the material characteristics of phenolic resin,the mechanism of the effects on machining rate is discussed.In addition,the material remove mechanism is concluded through the analysis of the machining results.%研究了电解电火花工艺加工酚醛树脂材料时,电解液浓度、加工电压及工具电极和工件之间的压力对加工速度的影响.结果表明:增加电解液浓度、加工电压及工具电极和工件之间的压力可提高加工速度.结合酚醛树脂材料的特性,分析论证了以上三种因素对加工速度的影响机理.通过对实验现象的分析归纳,总结了酚醛树脂材料在电解电火花加工过程中的材料蚀除机理.
