Abstract

Micro-EDM (Electro Discharge Machining) is widely used for precision manufacturing and drilling micro-holes in materials used in fuel nozzles, micro sensors and robots, surgical instruments, turbines etc. Present paper deals with drilling common C360 brass components by micro-machining and optimizing the process parameter using a hybrid approach of design of experiments (DoE) and grey relation analysis (GRA) concept. The three process responses considered are material removal rate (MRR), tool wear rate (TWR) and taper in drilled hole while the four selected controllable process parameters are capacitance(C), voltage(V), feed rate(f) and rotational speed of electrode (N). Significance of input factors on each response is analyzed with the help of a 24 full factorial by conducting 16 experiments at two levels for factors. Optimum levels of robustness for each process response are established through Taguchi’s S/N ratio. A combined grey relation grade is applied to find the process levels conducive for optimizing MRR and TWR simultaneously.

基于田口灰色关联分析的C360黄铜微细电火花加工同步参数优化

微细电火花加工广泛用于燃料喷嘴、微型传感器和机器人、手术器械、涡轮机等材料的精密制造和微孔钻削。本文采用实验设计(DoE)和灰色关联分析(GRA)的混合方法，研究了常用C360黄铜零件的微加工工艺参数优化问题。考虑的三个过程响应是材料去除率(MRR)、刀具磨损率(TWR)和钻孔锥度，而选择的四个可控过程参数是电容(C)、电压(V)、进给速度(f)和电极转速(N)。通过在两个因素水平上进行16次实验，利用24全因子分析了输入因素对每个响应的意义。通过田口的信噪比建立了每个过程响应的最佳鲁棒性水平。采用组合灰色关联度来寻找有利于同时优化MRR和TWR的工艺等级。

期刊介绍： Engineering Review is an international journal designed to foster the exchange of ideas and transfer of knowledge between scientists and engineers involved in various engineering sciences that deal with investigations related to design, materials, technology, maintenance and manufacturing processes. It is not limited to the specific details of science and engineering but is instead devoted to a very wide range of subfields in the engineering sciences. It provides an appropriate resort for publishing the papers covering prior applications – based on the research topics comprising the entire engineering spectrum. Topics of particular interest thus include: mechanical engineering, naval architecture and marine engineering, fundamental engineering sciences, electrical engineering, computer sciences and civil engineering. Manuscripts addressing other issues may also be considered if they relate to engineering oriented subjects. The contributions, which may be analytical, numerical or experimental, should be of significance to the progress of mentioned topics. Papers that are merely illustrations of established principles or procedures generally will not be accepted. Occasionally, the magazine is ready to publish high-quality-selected papers from the conference after being renovated, expanded and written in accordance with the rules of the magazine. The high standard of excellence for any of published papers will be ensured by peer-review procedure. The journal takes into consideration only original scientific papers.
