Interference analysis and simulation of abrasive belt grinding and polishing of blisk

Abstract

Blisk is a difficult processing part with complex structure. The polishing quality and accuracy of the blade surface will significantly affect its performance and life. A new abrasive belt system is developed to grind and polish the blade on the blisk. In view of the problem that the abrasive belt is easy to interfere with the adjacent blades in the grinding and polishing process, an algorithm for judging the critical interference state is proposed based on the structural characteristics of the abrasive belt tool system and the actual grinding and polishing process of the blades. On the basis of above, a new algorithm is developed to calculate the range of interference-free wrap angle of the abrasive belt tool system. This paper established a simulation model based on VERICUT software and simulated the process of the blisk polishing. The simulation and experiment results verifies the effectiveness of the algorithm.
