ABSTRACT:
A method and apparatus for cutting a workpiece by electrical discharges by means of a travelling wire electrode according to a path determined by a numerical control program without reducing the machining speed or the current flowing into the wire electrode. At least one of the support and guiding members of the wire electrode is displaced relative to the workpiece along a path resulting from shifting each point of the desired cutting path a predetermined distance in the direction of machining along a tangent to each point of such path. The angle between the tangent at each point of the path relative to the coordinate axes is determined, and each point of the path is shifted relative to the programmed path along coordinates having values proportional respectively to the sine and cosine of the angle.
