In order to achieve efficient and low impact polishing production of automotive die castings,an intelligent polishing robot control system for automobiles has been developed based on the Open CASCADE(OCC)software platform.The system structure is divided into four layers:user interface layer,algorithm layer,data structure layer,and 3D core layer.It is mainly composed of five modules,i.e.,operation simulation,3D display simulation,trajectory planning and optimization,post code,and dynamic simulation.It includes various interpolation algorithms and trajectory optimization algorithms,and can achieve ef-ficient and low impact trajectory planning and optimization.The system is applied to the polishing simulation of automotive en-gines,and the results show that the system can maintain the smoothness of the polishing trajectory,reduce the impact on the polishing robot joints,and improve the machining efficiency by 33％when optimizing the trajectory using time impact.The system ensures the smoothness and efficiency of the polishing process of automotive components.
