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.
