摘要

电火花加工(EDM)为金属材料的成形提供了许多优点。它还为国防工业中使用的钛合金提供了更好的表面质量。在本研究中，采用钛(Gr2)合金进行了不同电火花加工参数的实验。由于技术的进步，已经发展了许多新的工业工艺。对于要开发的产品，必须利用这些新方法来确定最佳参数。电火花加工实验采用田口法。通过方差分析(ANOVA)分析了测试参数对刀具磨损率、材料去除率、深度和表面粗糙度等性能特征的影响。利用二次回归分析揭示了实验结果与预测值之间的相关性。根据材料去除率(MRR)、刀具磨损率(TWR)、深度和表面粗糙度的方差分析结果，最有效的因素是电流，分别为99.66%、99.56%、87.95%和81.12%。在通电120 μs、通电8 μ A、关闭40 μs时，平均表面粗糙度的最佳值为3.29µm。

TAGUCHI OPTIMIZATION OF MULTIPLE PERFORMANCE CHARACTERISTICS IN THE ELECTRICAL DISCHARGE MACHINING OF THE TIGR2

Electrical discharge machining (EDM) provides many advantages for the shaping of metallic materials. It also provides better surface quality for Ti alloys used in the defense industry. In this study, experiments were carried out with different EDM parameters using the Titanium (Gr2) alloy. A number of novel industrial processes have been developed as a result of advances in technology. For a product to be developed, these novel approaches must be utilized to determine optimum parameters. The Taguchi method was applied in the experiments with EDM. The impact the test parameters had on the performance characteristics of tool wear rate, material removal rate, depth, and surface roughness were analyzed by the variance analysis (ANOVA). Quadratic regression analyses were carried out to reveal the correlation between the experimental results and the predicted values. According to the ANOVA results for material removal rate (MRR), tool wear rate (TWR), depth, and surface roughness, the most effective factor was amperage, at 99.66%, 99.56%, 87.95%, and 81.12%, respectively. The best value for average surface roughness was determined to be 3.29 µm obtained at 120 μs time-on, 8 A, and 40 μs time-off.
