摘要

针对某航空发动机TC4整体叶轮在数控加工过程中存在颤振、加工效率低及因加工变形而导致局部超差等问题，提出了相应的铣削参数优化解决方案。在进行切削力系数辨识试验获取TC4材料的切削力系数及锤击试验获取加工系统动力学特性参数的基础上，通过综合使用自行开发的铣削加工动力学仿真软件SimuCut和国外的CutPro软件进行动力学仿真与优化，获得了优化的切削参数。使用优化的切削参数进行加工，有效地消除了颤振和因加工变形引起的局部超差，提高了加工效率。

Abstract

Optimization of milling parameters is applied to solve the problems of chatter

low machining efficiency and local machining out-of-tolerance due to machining deformation in the fabrication of TC4 integrated impeller of an aeroengine. Based on the cutting force coefficients of TC4 material gained by cutting force coefficient identification tests and the dynamic parameters of the machining system gotten by hammer tests

the optimized cutting parameters are obtained by using the self-developed dynamic simulation software SimuCut for milling and the oversea counterpart CutPro synthetically. The optimized cutting parameters are used in practical milling process

and the machining deformation resulted from the machining chatter and the local out-of-tolerance are eliminated and the machining efficiency is improved.
