摘　　要：由于初始残余应力的作用,金属薄板平面加工普遍存在加工难度大,加工变形严重等问题,难以保证板面的加工质量。以不锈钢薄板的平面加工为基础,通过理论分析、仿真模拟和实验验证的方式,对金属薄板的加工形变进行较为系统的研究,分析了金属薄板加工形变的关键因素,总结了金属薄板残余应力分布形式以及有效避免加工形变的工艺方法,为类似金属板材加工提供理论参考依据。Due to the effect of initial residual stress,some problems exist in the sheet metal surface processing,such as difficulty in processing and serious processing deformation.It is difficult to guarantee the processing surface quality.This paper takes the surface processing of stainless steel sheet for example,by theoretical analysis,simulation and experimental verification,makes a systematic study of the processing deformation of steel metal,analyzes the key factor of the deformation of the metal sheet,summarises the residual stress distribution form and puts forward the processing method which is used to effectively avoid the processing deformation.The theoretical basis is provided for similar metal sheet processing.
