Processing parameters optimization on control of residual stresses and distortion during high-speed milling of thin-walled workpiece
In the aerospace and auto industries,the residual tensile stresses will cause the structures broke and damaged.Hence,different methods were considered to optimize the machining processes.In this article,a residual stresses calculation model using AdvantEdge 2D turning was integrated with 2D milling physical model in order to analyze high-speed milling thin-walled workpiece.Through optimizing the processing parameters (improving the cutting speed and decreasing the cutting depth) during high-speed milling,not only we can get a high removal rate and receive a distribution of equably surface residual stresses,but also a slowing down trend of in-depth residual stress can be obtained.In addition,we evaluate this method using a typical part at the sensitive area,and the machining quality can be improved obviously.
