Method of controlling an operation of a copy-cutting apparatus

An apparatus for controlling an operation of a copying apparatus which includes a tracer for tracing a contour of a pattern to be copied and a working machine having a working head being movable in conjunction with the tracer in a given relationship for effecting a given working operation for an object to be worked comprising:

• means for detecting coordinates of the tracer at operational points including at least a work start point, a copy start point and a copy end point;
• means for storing the detected coordinates;
• means for reading the stored coordinates out of the storing means;
• means for setting a position of the tracer by means of the readout coordinates;
• means for switching the copying apparatus between a position setting mode and a copying mode;
• and
• means for controlling the above means in such a manner that during the actual working operation the movement of the tracer is controlled by the readout coordinates, while the switching means being in the position setting mode, whereas in the copying mode the movement of the working head is controlled by the movement of the tracer which follows the pattern.
