In order to improve the efficiency and precision of abrasive belt grinding of the free-form surface, a novel trajectory planning approach based on machining accuracy control is proposed in this paper. At the same time, a method to optimize the size of the contact wheel based on the diploid genetic algorithm is also presented. Then, the effectiveness of the method is necessary to demonstrate through an abrasive belt grinding experiment of the aero-engine blade. The results show that the blade profile accuracy after grinding by using the proposed method can better meet the corresponding tolerance requirements, and the surface quality and accuracy of blade profile are improved effectively.
