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

There are many factors that influence welding distortion; in summary, these can be categorised into three main areas: materials, structure and process. Whilst ensuring the structural load-bearing capacity is maintained, weld dimensions should be kept as small as possible to minimise the impact of welding heat input on the material’s properties.

Manufacturing is the foundation of national strength, please pay attention to “metal processing” (mw1950pub).
