Abstract

An experimental investigation was conducted to determine the application of die sinker electrical discharge machining (EDM) as it applies to a hybrid titanium thermoplastic composite laminate material. Holes were drilled using a die sinker EDM. The effects of peak current, pulse time, and percent on-time on machinability of hybrid titanium composite material were evaluated in terms of material removal rate (MRR), tool wear rate, and cut quality. Experimental models relating each process response to the input parameters were developed and optimum operating conditions with a short cutting time, achieving the highest workpiece MRR, with very little tool wear were determined to occur at a peak current value of 8.60 A, a percent on-time of 36.12%, and a pulse time of 258 microseconds. After observing data acquired from experimentation, it was determined that while use of EDM is possible, for desirable quality it is not fast enough for industrial application.

摘要

开展了一项实验研究，以确定电火花成型加工（EDM）在混合钛热塑性复合材料层压板材料中的应用。使用电火花成型加工钻了孔。根据材料去除率（MRR）、刀具磨损率和切割质量，评估了峰值电流、脉冲时间和通电时间百分比对混合钛复合材料可加工性的影响。建立了将每个工艺响应与输入参数相关联的实验模型，并确定在峰值电流值为8.60 A、通电时间百分比为36.12%、脉冲时间为258微秒时，切割时间短、工件MRR最高且刀具磨损极小的最佳操作条件。在观察了从实验中获取的数据后，确定虽然可以使用电火花加工，但为了获得理想的质量，其速度对于工业应用来说不够快。
