Abstract—In this study, the concept of polishing using a cooperative robot is explored. A novel system that integrates wireless vibration monitoring technology with servo internal information is presented. In particular, a novel finishing system that utilizes the internal information of the force sensor installed in the base of a cooperative robot was developed. The proposed system can be used to detect human contact and improve the accuracy of machining. In this paper, a blade-shaped workpiece was machined using a Computer Numerical Control (CNC) machine that performs simultaneous 5-axis machining. The surface condition of the machined workpiece was clarified by using a wireless vibration measurement holder and internal servo information. In addition, raw vibration waveforms were observed during the cutting process to investigate the causes of chatter and vibration. The surface condition of the workpiece was examined based on the in-process vibration information, and the efficiency of polishing was improved by limiting the range of rough polishing by the proposed robot system. The prediction of the tool condition during machining and optimization of the polishing operation are discussed in the context of robot polishing. We report on how this method uses data from the previous process to achieve a higher rate in the next process.
