ABSTRACT:
A device for automatically controlling an electroerosion cutting machine in which a unit for selecting a direction of rotation of drive motors in the course of erosion working, includes a coincidence circuit and a reversible ring shift register whose outputs are connected to inputs of the coincidence circuit, whereas the latter's outputs are electrically coupled to coordinate drive motors which move an electroerosion tool relative to the workpiece, and an optical head relative to a coordinate follow table. The optical head is electrically connected to the register and coincidence circuit via a first amplifier having four divided outputs, two of which are connected to respective inputs of the ring shift register, whereas the remaining two are connected to the inputs of the coincidence circuit.
