The purpose of this study is to develop an instruction system for supporting to inherit skills on buffing process. As the first step, the technical characteristics of skilled worker were investigated in order to find the effective information for instructing to unskilled person or trainees in this system. Polishing load and relative rotation/translation between workpiece and buff were measured simultaneously by using 3-component load-cells and a motion capture system. Contact states between workpiece and buff were estimated from these data, and then compared with skilled and unskilled workers. During buffing, cyclic movement of workpiece to sideward direction was observed by each subject; however, it was found that the fluctuations of vertical polishing load and workpiece tilt per cycle obtained by skilled subject were significantly smaller than unskilled subjects.
