The device comprises a detector for teaching the position and the attitude of the machining head with respect to the work independently from the machining head in case of forming teaching data. A calculator is provided for calculating the spatial position and attitude entirely in the same manner as the detector with respect to the work by the stored data under playback condition so that the machining head takes with respect to the work. Also, a control unit is provided for controlling the position and the attitude of the jig in accordance with the calculated result of the calculator, and a drive unit for driving the jig on the basis of a command from the control unit.
