Experimental Study on Thermostatic Cutting Nickel-Base Superalloy GH4169

Abstract:

Nickel-base super alloy GH4169 is difficult to cutting and tool wear is very serious, because of its high strength, poor thermal conductivity, and serious work-hardening. In order to choose reasonable cutting parameters as to improve the processing efficiency, the cutting experiments were crarried out and the changes of workpiece material physical in cutting process were studied, and then thermostatic cutting method based on the longest distance is proposed in this paper. The best cutting temperature of carbide cutting tool YG8-GH4169 has been given. The experiments using diferent cutting parameters has proved the feasibility of thermostatic cutting method. Finally, the empirical formula of thermostatic cutting based on the cutting speed and feed rate is proposed, when using YG8 cutting GH4169.
