摘要：

Addressing the problem of grinding and polishing tool wear in the automatic grinding and polishing process，an issue that makes it difficult to establish an accurate grinding and polishing removal model to achieve a stable and consistent grinding and polishing effect，a robot grinding and polishing parameter optimization method considering time-varying wear is proposed. First of all，combining the rich information in the physical modeling method with the tracking learning characteristics of the regression modeling method，a regression model for grinding and polishing material removal that integrates prior knowledge is proposed. Such a model will greatly reduce the large amount of experimental data required. The proposed model can track the changes in grinding and polishing wear. The prediction results of the model used are compared with theoretical models and the support vector regression prediction model proposed in other research. Finally，the prediction model obtained is used to optimize the robot grinding and polishing parameters，and experimental verification is carried out on the polishing experiment platform of the hybrid robot. The results show that the proposed grinding and polishing material removal model fused with prior knowledge has higher prediction accuracy and less experimental data. The proposed optimization method for robot grinding and polishing parameters can effectively compensate for the wear of grinding and polishing tools，ensure the consistency of material removal in the grinding and polishing process，and improve the efficiency of grinding and polishing. © 2023 Tianjin University.
