摘要: 针对机器人在加工时易产生振动的问题，开展气囊抛光机器人振动特性对工件加工质量影响的研究。通过建立机器人气囊抛光系统动力学模型，分析抛光反力、主轴转动频率对气囊抛光系统振动影响；以石英玻璃为样件，进行机器人振动响应测量实验和抛光实验；研究不同工艺参数的系统振动对工件表面粗糙度、材料去除率和表面形貌的变化规律。实验结果表明：表面粗糙度、材料去除率随系统振动强度的增加而增大；下压量为0.2 mm、主轴转动频率为14~16 Hz、22~26 Hz的系统振动较小，材料去除率较低，获得表面粗糙度较小，适用于精抛阶段。该研究对优化机器人气囊抛光工艺参数，减小系统振动从而提高加工质量具有一定的理论和实践意义。
Abstract: To address the problem of vibration in the robot during machining, the influence of vibration char-acteristics of the bonnet polishing robot on the machining quality was studied. A dynamic model of the robot bonnet polishing system was established to analyze the influence of polishing force and spindle rotation frequency on the vibration of the bonnet polishing system. Quartz glass was used as the sample for measuring the robot’s vibration response and conducting polishing experiments. The study examined the changes in workpiece surface roughness, material removal rate, and sur-face morphology under different process parameters of system vibration. The experimental results show that the surface roughness and material removal rate increase with the increase of the vibra-tion intensity of the system. The system vibration is small, the material removal rate is low, and the surface roughness is small when the pressing amount is 0.2 mm, the spindle rotation frequency is 14~16 Hz and 22~26 Hz, which is suitable for the fine polishing stage. This study has theoretical and practical significance in improving machining quality by optimizing the process parameters of robot bonnet polishing to reduce system vibration.
