Abstract
The deformation straightening was studied. The construction of original geometrical model with machining residual stress was accomplished in a collaborative simulation environment combining machining process with straightening process. A modified dichotomy was proposed to calculate the straightening parameters. The influences of different constrains and straightening loads on the straightening were compared and analyzed. The coupling effects of initial residual stress and the induced stress due to the straightening load were discussed. The typical curves were obtained to guide the correcting production based on the finite element simulation results. The straightening experiments were designed to validate the FE simulation. The experiment results show the feasibility and effectiveness of the finite element model.
