ABSTRACT:
A wire-cut electroerosion machining method and apparatus in which the rate of axial travel of the electrode wire is temporarily increased immediately upon a change by the electrode wire of its course at a corner in a prescribed cutting path. The axial travel rate is preferably increased as a function of the angle of intersection defining the corner. Also, the time period in which the wire axial travel rate is increased should advantageously be varied as a function of, e.g. in inverse proportion to, the angle of intersection defining the corner.
