Notes:
Uneven distribution of the residual stress is the main factor causing the distortion of aworkpiece. Different clamping scheme may cause different clamping stress. Clamping stresscoupling with the residual stress inside the part induces different stress distribution, which affectscomponents’ machining distortion and service life. To reflect the relationship between clamps andresidual stress , finite element model with different clamping schemes were bulit and the clampingprocess was simulated. And the chip removal effect was taken into account using a material removalapproach based on element death technique. Stress distribution in the workpiece is analyzed andcompared under different clamping conditions. It is verified that clamping position has a significanteffect on the residual stress. Otherwise the clamping sequence has a little effect on the stressredistribution
