Abstract
An object of the present invention is to provide a method of teaching a position, in which greater loads are not applied to a workpiece, a machining tool and a mechanism for moving the workpiece. The method is characterized by the steps of: driving the motors with detecting exciting currents so as to move the workpiece from a position short of an object position to the object position; making the workpiece contact with the machining tool corresponding to the object position; temporally turning off the exciting currents of the all motors if at least one of the exciting currents is greater than a predetermined value; and storing a position of the workpiece as the object position if counter forces, which work from the machining tool to the arms and the motors, and frictional forces, which are generated in the arms and the motors, are balanced when the exciting currents are turned off and the workpiece is made contact with the machining tool.
