Residual stresses are generated in the machined layer for thin-wall parts cutting. The residual stresses impacts the working performance and fatigue strength of parts. The reasons of residual stress generation in the thin-wall parts cutting process are expounded. Affecting factors of residual stresses are also analyzed. At the same time

the domestic test methods of residual stress that  are commonly using at present are summarized. Finally

several feasible methods are resented to control and regulate residual stresses in thin-wall parts cutting.
