Abstract
Recently, high-combustion-efficiency jet engines have become essential in the aircraft industry. High burning temperatures are necessary to maximize the combustion efficiency of jet engines. Inconel 718, which has excellent mechanical and chemical properties, has been selected for use in many jet engine parts. However, it is difficult to cut this alloy because of its low-thermal-conductivity. Consequently, wet cutting is typically used to reduce the heat generated in cutting Inconel 718. In this study, the authors conducted experiments to examine the relationships between high-efficiency cutting and tool wear in high-pressure coolant system. These results indicate that, high-efficiency cutting is possible.
