The purpose of this research is to develop hi-speed and hi-accuracy machining system which is corresponded to 1 micron of accuracy. The servo data is the set of position command at every servo cycle time, which is minimum unit of position command to control servo motor in NC machining processes. The developed system has two methods to realize hi-speed and hi-accuracy machining. One is the geometric interpolation that generates the servo data directly from geometric model without NC program. The other is the prediction error compensation that simulates motion error and compensates it automatically. This report refers to the algorithms of the geometric interpolation and the prediction error compensation. Moreover the result of machining experiment using generated servo data from free surface model and compensation of motion error are described.
