Abstract

This paper concerns the residual stress formation during the processes of rigid kinematics mechanical surface treatment. Taking conventional turning as example, we examine the features of the deformation zone, which cause the principal residual stress deviation from speed and feed directions and their in-depth rotation governing in-plane shear residual stress formation. Three stress components of the plane residual stress state are presented as functionally combined. The existence of materials providing residual stress distribution by principally different ways is theoretically predicted. The formation of the residual stress states of different types is confirmed by experimental results. A hypothesis based on the simple shear cutting deformation approach is advanced to explain the revealed relationships.
