The purpose of this research is to develop a high-speed and high-accuracy machining systemthat corresponds to 1μm of accuracy. Servo data is the set of position commands at every servocycle time, which is the minimum unit of position commands required to control the servomotorin NC machining processes. The developed system has two processes to realize high-speed andhigh-accuracy machining by controlling the servo data. One is the geometric modelinterpolation process that generates servo data directly from a geometric model without usingan NC program. The other process is prediction error compensation, which simulates motionerrors and compensates for them automatically.This report describes the background of this research, which is the problems including in acurrent machining system such as an interpolation error, smoothing error, motion error andphysical errors in machining process. In addition, the basic concept of system is proposed. Anddevelopment of the prototype system, which is a combination of these two processes, isdescribed.
