- Abstract
During milling, chatter will lead to the increase of cutting force amplitude and of cutting force fluctuation, leading to the reduction of workpiece surface quality. In order to solve this problem, firstly, according to the flutter stability analysis algorithm, a dynamic milling system for titanium alloy Ti6 Al4 V thin-walled parts was established to obtain the stability lobe diagram. Then,the finite element simulation and experiment were used to verify. The results show that the stability analysis results, the experimental and finite element simulation results have good consistency, verifying the correctness of stability study. The results can provide a theoretical basis for thin-wall milling of titanium alloy, and set reasonable processing parameters to avoid the occurrence of flutter, providing theoretical basis and technical guidance for thin-wall milling of titanium alloy.
