复杂形体钛合金零件的加工工艺研究

摘要

钛合金材料具有导热系数小、弹性模量低、化学活性高等特点,机械加工较为困难.以某发动机轴流稳流装置为例,对复杂形体钛合金零件工艺难点进行分析,通过划分实际加工阶段、选用刀具、设计工装等流程,总结出钛合金零件加工和热装配的普遍原则.%Titanium alloy material has the characteristics of small thermal conductivity,low elastic modulus and high chemical activity,and it is more difficult for machining.Taking the axial flow stabilizer of an engine as an example,the difficulties in machining of the complex titanium ahoy parts were analyzed.Through the division of the actual processing stage,tool selection and tooling design,summarized the general principles for machining of titanium alloy parts and for thermal assembly.
