Abstract

Abstract The use of thin film-coated micro-tool electrode introduced a new technical solution to bring the best technical–economic efficiency in the field of non-conventional machining processes. Multi-objective optimization of process parameters in micro-electrical discharge machining (EDM) is very limited with the help of thin film-coated micro-tool, which brought benefits for the industry. In this research work, the technological parameters such as voltage (V), spindle rotation, and capacitance (C) in micro-EDM using carbon-coated electrode were optimized, and Z-coordinate depth of cut and tool wear rate were selected as response variables. Taguchi is combined with Deng’s method to solve this multi-objective decision problem. The results showed that Taguchi–Deng’s method is the right solution for multi-target decision in micro-EDM using the coated electrode. C is the strongest influence on optimal efficiency, and it is the smallest with V. The machining quality under optimal conditions is improved.

碳包电极微电火花加工中嵌入ahp的邓混合MCDM模型的开发

摘要利用薄膜包覆微工具电极引入了一种新的技术解决方案，在非常规加工工艺领域带来了最佳的技术经济效益。利用薄膜包覆微刀具对微细电火花加工工艺参数进行多目标优化是非常有限的，为工业带来了效益。本研究以碳包覆电极微细电火花加工的电压(V)、主轴转速、电容(C)等工艺参数为优化参数，选取z坐标切削深度和刀具磨损率作为响应变量。田口将邓的方法结合起来解决了这一多目标决策问题。结果表明，Taguchi-Deng方法是镀层电极微细电火花加工中多目标决策的正确解决方案。C对最优效率的影响最大，对v的影响最小，最优条件下的加工质量得到改善。
