This paper deals with the development of high speed and high accuracy machining system, which is able to compensate for the effect of a tool deformation, a motion error and so on, based on servo data. The proposed system has two functions, which are newly proposed, to realize high speed and high accuracy machining. One is the geometrical interpolation function, which directly generates servo data from geometric model. The other is the error compensation function, which estimates machining errors by simulating using servo data, and compensates for these errors based on servo data. The servo data is a position data calculated by interpolating and smoothing in each servo sampling cycle. In this paper, the motion error is compensated as an example to verify proposed system. As a result of compensate simulation, it is evident that proposed system is able to reduce motion error using estimate compensate method.
