针对大型薄壁筒节类零件由于直径大，壁厚薄导致刚度较低，在切削力、切削热、残余应力和夹紧力等因素影响下，易发生加工变形，不易控制加工精度，加工效率低的问题。以反应堆压力容器的通风罩支承为例，介绍一种大型薄壁筒节类零件防变形加工方法。
針對大型薄壁筒節類零件由于直徑大，壁厚薄導緻剛度較低，在切削力、切削熱、殘餘應力和夾緊力等因素影響下，易髮生加工變形，不易控製加工精度，加工效率低的問題。以反應堆壓力容器的通風罩支承為例，介紹一種大型薄壁筒節類零件防變形加工方法。

Machining deformation, hardly controlled machining accuracy and low machining efficiency can happen easily on Large thin-wall shell course parts under the influence of cutting force, cutting heat, residual stress and clamping force due to the large diameter and thin wall-caused low stiffness. The paper takes the support of the ventilation hood of reactor pressure vessels for example to introduce a machining method to prevent large thin-wall shell course parts from deformation.
