Influence of the Temperature and Mechanical Stresses Generated by Milling Process in Machined Part Surfaces on their Accuracy

摘要

Surface generation by milling process involves the occurrence of some complex effects that affect surface quality. The most important effects of the milling on the generated surface are heating, plastic strain and residual stress. The aim of the present research is to analyze the influence of the work piece temperatures and residual stress distributions generated by milling in the machined surfaces on its accuracy. Two types of materials and different cutting parameters have been used in order to determine the above mentioned connection. The obtained results show that the temperature and residual stress generated by milling influences the surface deviations from flatness.
