S1302-1-6 High Efficiency cutting of Inconel 718 with AJA method

Abstract

Inconel 718 is one of a family of nickel-base superalloy. However, Inconel 718 has disadvantageous properties for machining. These properties shorten tool lives. Therefore, it is difficult to increase the cutting speed of Inconel 718. But high-speed and high-efficiency machining is demanded. In this study, the high speed finish-turning of Inconel 718 was conducted. To improve the tool life, the authors proposed the new lubrication method called "Air Jet Assisted (AJA) Machining," in which the compressed air was applied to the normal wet cutting. It was found that this method improved the tool life in comparison with conventional wet cutting.
