摘要

CNC polishing is the key technology to realize the automation and high efficiency of the surface finishing of the blisk. And the polishing path planning has a significant influence on the surface quality. When polishing the free-form surface, the deviation of radial compression quantity along the contact curve of abrasive cloth wheel leads to poor consistency of material removal quantity. Based on the geometric analysis of the extrusion deformation of the abrasive cloth wheel, a compression deformation distribution model along the contact curve on the free-form surface was established. The optimization model of tool orientation at one cutter location was established, and the improved Partical Swarm Optimization (PSO) was used to solve the problem. The objective function of optimization was evaluated by minimizing the maximum compression deviation along the contact curve. Then the curves of adjacent cutter contact trajectories are calculated. Finally, the correctness and the effectiveness of the proposed method were verified by experiments. The results show that the contour and roughness of the polished area are improved significantly.
