An Experimental Study on Optimization of Cutting Parameters for Disk Milling Titanium Blisk

Abstract:

Blisks are important components of aircraft engines. Its machining plays an important role in a aerospace industry. Blisk processing efficiency has become a hot topic in the field of machining. Disk milling is a new processing method to achieve efficiency. In order to optimize disk milling process parameters of blisk, the use of full-factor experimental for researching TC4 titanium disc milling process. Analyze the impact of different cutting parameters on cutting force, the results show: during milling titanium by Discal Cutter, with the increasing of feed per tooth, the cutting force increases. But cutting forces in three directions has the different influence. Feed per tooth corresponding with radial cutting depth. In order to guarantee the material removal rate, it can be selected smaller feed per tooth and larger radial cutting depth. Through the stress simulation analysis on the blade, it can be carried out that the maximum strain of blade is concentrated at the tip arc. The equivalent stress is mainly concentrated at the main cutting edge and the tip arc. It can provide the basis for future tool design.
