Abstract
A method for teaching a machining line to be machined is disclosed. A borderline is formed along the machining line on a workpiece. Then, a borderline sensor is moved across the borderline at each sensing position. The positions of the sensor are stored as a teaching position at each time when the borderline is detected by the sensor. The sensing interval between each teaching position is automatically adjusted according to the change in the curvature of the borderline. At the place where the curvature of the borderline becomes large, the sensing interval is shortened in order to maintain teaching accuracy.
