Abstract: Machining part distortion is due to residual stresses induced by previous manufacturing processes. This study aims to evaluate theinfluence of machining conditions on AISI 316L plate distortion. Therefore, a special experimental device with force sensorsintegrated in the clamping system and numerical model of distortion were developed. Residual stresses due to previous machiningprocesses were measured using a layer removal method and neutron diffraction technique. Then, distributions of theseresidual stresses were integrated in a developed model of machining distortion, which considers the clamping and machiningsequence effects after each stage of the toolpath. A comparison of the experimental and numerical results revealed that the finiteelement method can adequately predict machining distortion. The results also suggest that clamping and machining sequence canaffect part distortion.
