摘要
Rapid tool wear is one of the major machinability aspects of nickel-based super alloys. In this article, the effect of cutting parameters on material removal rate and tool wear of a whisker ceramic insert in turning of Inconel 625 was examined. Optical microscope and scanning electron microscope were applied to measure and study tool wear mechanism. Response surface method was used to develop a mathematical model which confirmed by experimental tests. The statistical analysis done by analysis of variance showed that depth of cut is the most effective factor on the tool wear. Experiments showed that increment of feed rate had an insignificant effect on the progress of flank wear, and it is an important controlling factor when material removal rate is considered as a desired output. Finally, optimized cutting condition is presented in this work.

快速刀具磨损是镍基超级合金的主要可加工性方面之一。在本文中，研究了切削参数对Inconel 625车削中晶须陶瓷刀片的材料去除率和刀具磨损的影响。应用光学显微镜和扫描电子显微镜测量和研究刀具磨损机理。响应面法用于开发通过实验测试证实的数学模型。通过方差分析进行的统计分析表明，切削深度是刀具磨损的最有效因素。实验表明，进给速率的增加对后刀面磨损的进展没有显着影响，并且当材料去除率被认为是期望的输出时，它是一个重要的控制因素。最后，本文介绍了优化的切削条件。
