Parameters Optimization of High Speed Milling Based on the Dynamic Behaviour of Spindle System

Abstract:

A high speed milling process parameters optimization method with considering the dynamic behavior of the spindle system is presented. Based on the dynamic behavior of spindle system, an optimization model which integrates the interaction characteristics of spindle system dynamic behavior and the parameters is constructed. Maximizing the limited depth of cut which can avoid the occurrence of chatter vibration and maximizing the production rate are considered as objectives. By using Artificial Bee Colony algorithm, the optimal milling parameters are obtained. Example and experimental results show that, to get the optimal results, spindle system dynamic behavior must be considered as variable in the optimization process.
