Abstract: A method of and an apparatus for monitoring and programming functioning of a machine for machining workpieces, in particular, a spark erosion machine, in which separate functions are displayed on a window of the apparatus screen, one or more of the displayed functions is/are selected and then set up valuewise in a further window of the apparatus screen.

Abstract: A method of electroerosive wire cutting at least one shaped piece in a workpiece, in which it is cut by a solid cut along a first path, at least one parting cut along a second path, and at least one finish cut along the first and second paths, the sequence of cuts being variable according to the operating conditions. The operating conditions can include presence of a user so that the parting cut is carried out upon the presence of the operator.

Abstract: A process and a device for numeric path control for electroerosion machines having a wire electrode stretched between two guides and a guide connected to a work piece are proposed. To lessen cutting errors on work pieces to be processed, and thus to decrease the amount of geometric information that must be fed into a numeric control of a wire electrode erosion machine, it is proposed that only a few figures for track points be supplied and intermediate track points be determined by interpolation. The interpolation for the intermediate track points of the two movable guides is carried out according to various types. For example, one interpolation is linear, while the other interpolation is performed according to a circular function.
