Nowadays, the Wire Electrical Discharge Machining (WEDM) process was also working to cut the hard titanium alloys. During the WEDM, the generation of high temperatures was used to melt and vaporize and also flushed away the hard titanium alloy. The tough Ti–6Al–2Sn–4Zr–2Mo alloy was machined in the current research by the WEDM method and machining features such as surface roughness (SR) and Material Removal Rate (MRR) were statistically evaluated to achieve optimum performance. The investigations were performed using the Taguchi orthogonal array technique. The optimum process factors were defined from the main effect plot 32 μs, 3 m/min, and 12 g for material removal rate and as 10 μs, 32 μs, 7 m/min, and 12 g for surface roughness. The best essential parameters were established from the Analysis of variance (ANOVA) analysis. The pulse on-time current and pulse off time were identified as important parameters for the material removal rate with a contribution of 23.60%, 5.91%, and 65.02%. The best essential parameters for surface roughness were pulse on time, pulse off time, and a combination of pulse on-time and pulse off time with a percentage contribution of 22.71% and 36.88% respectively.Moreover, the machined surface was examined using the Scanning Electron Microscope (SEM).

如今，线切割加工 (WEDM) 工艺也用于切割硬质钛合金。在 WEDM 过程中，产生的高温被用来熔化和汽化，并冲走硬质钛合金。在目前的研究中，采用 WEDM 方法加工坚韧的 Ti-6Al-2Sn-4Zr-2Mo 合金，并对表面粗糙度 (SR) 和材料去除率 (MRR) 等加工特征进行统计评估，以实现最佳性能。使用田口正交阵列技术进行调查。最佳工艺因子由主效应图定义，材料去除速率为 32 μs、3 m/min 和 12 g，表面粗糙度为 10 μs、32 μs、7 m/min 和 12 g。最好的基本参数是从方差分析（方差分析）分析。脉冲导通时间电流和脉冲关断时间被确定为材料去除率的重要参数，贡献率分别为 23.60%、5.91% 和 65.02%。表面粗糙度的最佳基本参数是脉冲开启时间、脉冲关闭时间以及脉冲开启时间和脉冲关闭时间的组合，其百分比贡献分别为 22.71% 和 36.88%。此外，使用扫描仪检查加工表面电子显微镜（SEM）。
