In this study, a novel method of Wire Electrical Discharge Turning (WEDT) by inclining the wire electrode is introduced. Response Surface Methodology (RSM) is employed to conduct the experiments by varying pulse-on-time, spindle rotational speed, and inclination angle at three levels, where Volumetric Material Removal Rate (VMRR) and the Average Surface Roughness (R_a) were considered as the response outcomes. It has been observed that the inclination of wire can improve the VMRR and R_a. The surface microstructure has also been studied with the help of FESEM images, and accumulations of elongated craters leading to the formation of crater-channels are observed. The formation of these crater-channels is influenced by the inclination angle and the spindle rotational speed. The observed surface cracks in the generated surface are very less in number and in some localized positions only. The study also focuses on arc-spark characteristics of voltage waveforms taken during the experiments. It is observed that at arcing conditions, a shiny surface is produced, and on the other hand, sparking conditions produce a dull and burnt surface. Finally, a multi-stage WEDT strategy is proposed to produce a cylindrical surface with high VMRR and superior surface characteristics.

在这项研究中，介绍了一种通过倾斜金属丝电极来进行金属丝放电加工（WEDT）的新方法。使用响应表面方法（RSM）通过在三个级别上改变脉冲接通时间，主轴转速和倾斜角来进行实验，其中考虑了体积材料去除率（VMRR）和平均表面粗糙度（R _a）作为响应结果。已经观察到，导线的倾斜可以改善VMRR和R _a。还借助FESEM图像研究了表面微观结构，并观察到细长的坑坑的堆积导致形成坑坑通道。这些弹坑通道的形成受倾斜角度和主轴转速的影响。在生成的表面中观察到的表面裂纹的数量非常少，仅在某些局部位置。该研究还着重于实验过程中获得的电压波形的电弧火花特性。可以观察到，在电弧放电条件下会产生光亮的表面，而在火花放电条件下会产生暗淡和燃烧的表面。最后，提出了一种多阶段的WEDT策略来生产具有高VMRR和优异表面特性的圆柱表面。
