Abstract

PURPOSE:To make possible rapid cutting operation by a method wherein when a wire electrode is disconnected in a cutting process and an unmachined part is left, the position of this unbroken point is indicated by an indicator. CONSTITUTION:When cutting operation is continued for a work 20 until the final cutting process, a wire electrode 10 is disconnected at the same processing point by more than specified times and an unprocessed part is left in the work 20, the position of this unprocessed part is stored in a memory of a CNC device 42 and the information in this memory is indicated on an indicator. An operator discriminates easily the position of the unprocessed part of the work 20 by this indicator, changes processing conditions so that the wire electrode 10 will not be disconnected. The wire electrode 10 is supplied again automatically to the starting point of processing on the unprocessed part of the work 20 in order to cut the unprocessed part.
