Development of hi-speed and hi-accuracy machining system based on servo data control

Verification of the machined accuracy using contour cutting path

Abstract

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 in NC machining processes. The servo data is directly generated by geometric model interpolation without NC program. And motion errors are simulated and compensated automatically. This report refers to the result accuracy of machining experiment by adapting the geometric model interpolation and compensation of motion error by using contour cutting path.
