为了提高Inconel 718的可加工性，在过去的十年中，通过修改工具和加工工艺已经完成了许多工作。然而，与常规车削工艺（CT）相比，最近开发的影响Inconel 718可加工性的低温-超声波辅助车削（CUAT）工艺尚未引起人们的注意。本文使用本地开发的超声辅助车削（UAT）和CUAT设备分析了Inconel 718的可加工性。已经研究了Inconel 718的UAT工艺对行业推荐的切削参数的影响。表面粗糙度（ R _a）和功耗是在UAT流程下测量的，然后与CT流程进行比较。粒子群优化（PSO）算法用于识别最佳切削参数，以实现UAT和CT工艺的最小 R _a和功耗。与UAT和CT工艺相比，优化参数被认为可以确认CUAT的有用性。这项研究工作的实验结果证实了CUAT工艺相对于UAT和CT工艺在 R _a和芯片形态方面的积极作用。 [R _一与UAT和CT过程相比，CUAT过程中的值分别显着降低。与CT工艺相比，UAT和CUAT工艺导致不连续的切屑具有较小的切屑厚度。结果已与当地中小型企业共享，使用CUAT和UAT改善切削性能有望使该行业受益。此外，实施了一种可持续性评估模型，以单一集成方法研究CUAT在加工性能以及可持续性有效性方面的效果。

Inconel 718 machining performance evaluation using indigenously developed hybrid machining facilities: experimental investigation and sustainability assessment

To improve the machinability of Inconel 718, a lot of work has been done in the past decade by modifying tools and machining processes. However, a recently developed cryogenic-ultrasonic assisted turning (CUAT) process influencing the machinability of Inconel 718 as compared to the conventional turning process (CT) has not been conspicuously presented. This paper analyzes the machinability of Inconel 718 using indigenously developed ultrasonic assisted turning (UAT) and CUAT facilities. The influence of the UAT process of Inconel 718 on cutting parameters recommended by the industry has been investigated. Surface roughness ( R _a) and power consumption are measured under the UAT process and then compared with the CT process. Particle swarm optimization (PSO) algorithm is used to identify the optimum cutting parameters to achieve minimum R _a and power consumption for UAT and CT processes. The optimized parameters are considered to confirm the usefulness of CUAT as compared to UAT and CT processes. Experimental results of this research work endorse positive effects of the CUAT process over UAT and CT processes in terms of R _a and chip morphology. R _a values under the CUAT process are reduced significantly in comparison to UAT and CT processes, respectively. UAT and CUAT processes resulted in discontinuous chips having smaller chip thickness in comparison to the CT process. The results are being shared with the local SMEs, and the industry is anticipated to be benefited in terms of improving cutting performance using CUAT and UAT. Moreover, a sustainability assessment model is implemented to investigate the effect of CUAT in terms of machining performance as well as sustainability effectiveness in a single integrated approach.
