Abstract�� Digitizing of face gear tooth surface is one of the key technologies on the tooth surface measurement. Aiming at the sampling of tooth surface on CMM(coordinate measuring machine), a method to determine the quantity of the sampling mesh points according to given precision was presented. The boundary lines of sampling mesh were adapted firstly and the initial sampling mesh could be achieved by the method of cutting-planes. According to the given quantity of the sampling mesh points, there was iterative computation for the initial sampling mesh by the adaptive sampling algorithm based on the measure of curvature, and then the adaptive programming method of face gear tooth surface was developed.
