Investigation of the Machinability of GTD-111 Type Nickel-Base Superalloy During Face Milling

Abstract

In this paper, the authors investigate the effect of technological parameters on the face milling of GTD-111 type nickel-base superalloys. These alloys are among the most difficult to machine and are widely used as a base material for gas turbine components in the aerospace and energy industries. The aim of this paper is to determine, using the Taguchi method, those parameters that have the greatest influence on cutting force and tool wear. A rotary force meter was used to measure the cutting force and cutting torque, and then the inserts used were examined used under a microscope. Results show that feed per tooth has the greatest effect on cutting forces and tool wear. In order to avoid the formation of edge deposits, it is advisable to use higher cutting speeds and compressed air cooling.
