Abstract

This study presents the analysis of wire-cut electro-discharge machining (WIRE-EDM) of polymer composite material (PCM). The conductivity of the workpiece is improved by using 1 mm thick titanium plates (layers) sandwiched on the PCM. Input process parameters selected are variable voltage (50-100 V), pulse duration (5-15 μs), and pause time (10-50 μs), while the cut-width (kerf) is recognized as an output parameter. Experimentation was carried out by following the central composition design (CCD) design matrix. Analysis of variance was applied to investigate the effect of process parameters on the cut-width of the PCM parts and develop the theoretical model. The results demonstrated that voltage and pulse duration significantly affect the cut-width accuracy of PCM. Furthermore, the theoretical model of machining is developed and illustrates the efficacy within the acceptable range. Finally, it is concluded that the model is an excellent way to successfully estimate the correction factors to machine complex-shaped PCM parts.

摘要

本研究对聚合物复合材料（PCM）的电火花线切割加工（WIRE-EDM）进行了分析。通过在PCM上夹入1毫米厚的钛板（层）来提高工件的导电性。所选的输入工艺参数为可变电压（50 - 100伏）、脉冲持续时间（5 - 15微秒）和暂停时间（10 - 50微秒），而切割宽度（切口）被视为输出参数。实验按照中心复合设计（CCD）设计矩阵进行。应用方差分析来研究工艺参数对PCM零件切割宽度的影响，并建立理论模型。结果表明，电压和脉冲持续时间对PCM的切割宽度精度有显著影响。此外，还建立了加工理论模型，并说明了其在可接受范围内的有效性。最后得出结论，该模型是成功估计加工复杂形状PCM零件校正因子的一种极佳方法。
