Abstract

Since the cutting tools used in machining process of super alloys are subjected to high cutting forces, accordingly tools life is reduced, therefore improvement in alloys machining and reducing cutting forces to achieve longer tools life is an essential necessity. In this research, the effect of changes in feed rate on cutting forces in machining process of nickel based super alloys is investigated. Cutting tools used in this experiment was a tungsten carbide material, model 890, geometry square shaped and specification of SNMG 120412. Also the tools has been coated using physical vapor deposition by chemical composition of TiN/TiCN/AlTiSiN in both micro and nano layer conditions. According to the results, as the feed rate is increased cutting forces mostly increases in both micro and nano layer coating conditions. . Generally in this research, application of micro layer coating results in less cutting forces compared to nano layer coating, so it can be said that micro layer coating has a better performance
