摘要

针对 TC21 钛合金转轴梁双闭角深槽腔类零件铣削效率低的问题，从材料和结构分析出发，基于生产实践，从零点系统、夹具设计、零件工艺凸台设计、刀具方案、切削参数、换刀方式等方面，研究 TC21 钛合金转轴梁深槽腔及双闭角区域的高效切削技术，总结了一套完整的结合零点定位和大悬伸快进给铣削的方案。对比原方案，加工周期缩短 50% 以上。

Abstract

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%.
