Aiming at the low milling efficiency of TC21 titanium alloy shaft beam double closed angle deep groove cavity parts

this article studies the high-efficiency cutting of deep groove cavity and double closed angle region of TC21 titanium alloy shaft beam from the aspects of zero point system

fixture design

part process boss design

tooling scheme

cutting parameters

tool change method

et al

based on the production practice

material and structure analysis. It summarizes a complete set of zero point positioning and large overhang fast feed milling solutions. Compared with the original plan

the processing cycle is shortened by more than 50%.
