According to the characteristics of rotary symmetrical surface and the principle of track envelope, a mathematical model on optical surface grinding was established. The surface figure error of rotation symmetric surface induced by the position error and radius error of grinding wheel was analyzed. The error model of rotation symmetric surface was established, and then position error and radius error of grinding wheel was identified and separated. The error compensation method of position error and radius error was used to improve the surface figure accuracy of rotation symmetric curved surface. Based on the grinding machine developed by National University of Defense Technology, the compensation method was proved to be effective, and bring instructive guide for grinding of this kind workpiece.
