摘要： A programming apparatus for an electroerosion cutting machine with two jig tables displaced by motion screw comprising: a counter-commutator controlling motors in the course of machining piece sectors tilted with respect to coordinate axes; pulse angular displacement sensors, each having an element sensing the revolutions of the respective motion screws and mounted together with the latter on the same roll; and sensors reacting to the actions produced by said element due to the revolutions of the respective motion screw.
