Abstract

The amount of electrode wear in micro-EDM has a direct effect on the dimensional accuracy of the machined hole. Therefore, improving the corrosion resistance of electrodes in micro-EDM is still of great interest. The effective coating of thin film for the micro tool electrodes in the case of micro-EDM can lead to minimize the electrode wear which eventually improve the productivity and machining quality. In the present study, experiments were performed on micro-EDM using carbon coated tool electrode and optimized using Taguchi-Topsis to investigate optimum levels of Depth of cut ( Z ) and overcut ( OVC ). It was concluded that optimum conditions had improved significantly using carbon coated micro tool electrode. Optimal levels of technological parameters include V = 160 V, C = 10000 pF, RPM = 600 rpm, and Z opt = 2.525 mm, OVC opt = 65.257  m. The quality of the machined surface with the coated electrode at optimal conditions is analysed and evaluated. The Topsis method is a suitable solution to this problem, and the steps to perform the calculation in this technique are simple.

碳涂层微电极刀具微细电火花加工工艺的优化

微细电火花加工中电极的磨损量直接影响加工孔的尺寸精度。因此，提高微细电火花加工中电极的耐腐蚀性仍然是人们关注的焦点。在微细电火花加工的情况下，为微细工具电极有效地涂覆薄膜可以最大限度地减少电极磨损，从而最终提高生产率和加工质量。在本研究中，使用碳涂层工具电极对微细电火花加工进行了实验，并使用田口Topsis进行了优化，以研究最佳切割深度（Z）和过切割（OVC）水平。结果表明，使用碳涂层微工具电极，优化条件得到了显著改善。工艺参数的最佳水平包括V=160 V，C=10000 pF，RPM=600 RPM，Z opt=2.525 mm，OVC opt=65.257 m.分析和评估在最佳条件下具有涂层电极的机械加工表面的质量。Topsis方法是解决这个问题的合适方法，并且在该技术中执行计算的步骤很简单。
