Abstract Nickel-based superalloys have many beneficial mechanical and manufacturing properties and have been used in various industries. However, the machining process and efficiency of these superalloys can be challenging due to several non-ideal factors such as undesirable chips flow, localized plastic deformation of the workpiece, and especially the tool wear. It has been shown that hybrid processes, including high-pressure jet-assisted machining (HPJAM), can be performed to improve machining efficiency. This work represents experimental methods to investigate and to quantify the effect of high-pressure jet-assisted machining on the tool wear mechanisms. The influence of variation of the turning parameters such as cutting speed, feed rate, and cutting fluid pressure on wear mechanisms was investigated along the tool rake face with respect to the position of the nozzles. An optical microscope, a scanning electron microscope (SEM), and energy-dispersive x-ray spectroscopy (EDS) analyses were used to assess the experiments. Experimental results showed that the abrasion wear was reduced, as the cutting fluid pressure was increased. The adhesion wear was minimized when an optimum fluid pressure range was used. The same behavior was observed in the development of notch wear. According to the measured parameters, the minimum notch wear occurred at the pressure of 70-bar. The tool life could be maximized by reduction of the tool wear, and the tool wear mechanisms can be better controlled if the high-pressure jet-assisted machining is performed under an optimum pressure range. Therefore, the tool wear, tool life, and material removal rates can be improved by optimizing the pressure levels and cutting parameters.

摘要 镍基高温合金具有许多有益的机械和制造性能，已被用于各个行业。然而，由于一些非理想因素，如不良的切屑流动、工件的局部塑性变形，尤其是刀具磨损，这些高温合金的加工工艺和效率可能具有挑战性。已经表明，可以执行包括高压射流辅助加工 (HPJAM) 在内的混合工艺来提高加工效率。这项工作代表了研究和量化高压射流辅助加工对刀具磨损机制的影响的实验方法。切削速度、进给量等车削参数变化的影响 沿着刀具前刀面相对于喷嘴的位置研究了切削液压力对磨损机制的影响。使用光学显微镜、扫描电子显微镜 (SEM) 和能量色散 X 射线光谱 (EDS) 分析来评估实验。实验结果表明，随着切削液压力的增加，磨损减少。当使用最佳流体压力范围时，粘附磨损被最小化。在凹口磨损的发展中观察到相同的行为。根据测量参数，在 70 巴的压力下出现最小的缺口磨损。减少刀具磨损可以最大限度地延长刀具寿命，如果在最佳压力范围内进行高压射流辅助加工，可以更好地控制刀具磨损机制。所以，
