本发明属于残余应力加工变形控制技术领域，尤其涉及一种工件加工变形的控制方法。背景技术：加工变形主要由毛坯初始残余应力、装卡力、切削力和切削热和加工引入残余应力这四个因素造成

In the development chain of humanoid robots, lightweight is an eternal theme. In order to reduce the burden on the motor and leave space for the range, engineers are eager to hollow out every aluminium alloy structural part. As a result, ultra-thin-walled parts with a wall thickness of 0.5mm-1.0mm have become the norm.
