航空薄壁件加工变形研究现状分析

Research Status of Machining Deformation in Aeronautical Thin-Walled Parts

薄壁件加工变形控制是现代航空制造业的重要课题。造成薄壁工件加工变形的主要原因是毛坯初始残余应力、装夹系统、切削力与切削热、工艺方案和加工参数以及刀具、机床等。依据采用时间的不同,将现有加工变形控制方法分成三个阶段,分析总结了各阶段加工变形控制方法的原理、现状和特点。

Machining deformation control of thin-walled parts was an important issue in modern aviation manufacturing industry. The main cause of the deformation in thin-walled parts were the initial residual stress in roughcasts, clamping system, cutting force and heat, process plan and processing parameters as well as cutting tools, machine tools, etc. Depending on the time of use, the existing methods of machining deformation control were divided into three stages. The principle, present situation and characteristics of machining deformation control methods in each stage are analyzed and summarized.
