This paper deals with the development of the die-finishing robotic system which is controlled by the CAD/CAM system. This system consists of the host computer, the robot controller, the grinding condition controller, the grinding tools and the exclusive 7-axis robot. A tool path, tool postures at grinding points and grinding conditions are generated in the host computer of CAD/CAM system by means of the simulation of surface conditions, in which a grinding phenomenon is theoretically analyzed. These informations are integrated into a robotic driving data. The robot controller controls motions of the exclusive 7-axis robot on the basis of a robotic driving data. Similarly, the grinding condition controller controls normal grinding forces and circumferential speeds by means of the grinding tool equipped with an air cylinder and a motor. As the result of applying this robotic system to a die-finishing process, it is proved that this system enables to keep a surface quality after finishing as good as one by usual finishing method (manual finishing) and reduces a die finishing time by 70%.
