A position control method for aligning a workpiece in a machining apparatus. An alignment pattern, such as a diamond, is provided on the surface of the workpiece. The alignment pattern and the surrounding region are sensed by an image pickup television camera, the output of which is converted to binary form. From the binary data, the central point of the pattern is calculated. The difference between this central point and a reference point is then determined, and the result used to control the position of the workpiece via a positioning mechanism.
