Abstract:Using the finite element method to numerically simulate the accurate turning of thin-walled parts, examines the influence between cutting stress, spindle speed and feed rate. Try to find out the relationship between the cutting stress and rebound deformation, and the way of the further study about the controling of rebound deformation.
Key words:accurate turning;rebound deformation;cutting stress
