Abstract

Aiming at the chatter problem in the finishing processes of the integral impellers, a process optimization method of continuous non-uniform allowance chatter suppression based on the least square method was proposed: The least square method was used to fit the non-uniform allowance modeling. The stiffness coefficients and natural frequencies of the workpiece-tool system were obtained by modal analysis: According to the principles of regenerative chatter analysis, the limit deep lobe graphs of uniform and non-uniform continuous margin blades in the chatter stability region are established. It is proved by the stable lobe diagram that the non-uniform allowance blade based on the least square method can effectively improve the stiffness coefficient and natural frequency of the work-tool system. Finally, the effectiveness of the analysis is proved by the milling experiment of the integral impeller. It has a significant effect on chatter suppression and has an effective guiding role in practical integral impeller manufacturing.
