Abstract
A computing device compensates a coordinate of a position device for a computerized numerical control (CNC) machine. The computing device generates a point cloud according to contour points of the position device. The computing device deletes selected contour points from the point cloud upon the condition that the distance corresponding to each selected contour point exceeds a predetermined threshold. The computing device calculates an average coordinate of the contour points which are remained in the point cloud.
