<p>It is an object of the invention to provide method and apparatus in which an operation to decide a trace of a tool to be moved which is used for processing a reference surface of a solid such as an electrode or the like in a numerical controlled discharge machine tool is automated. An origin position is set on the basis of figure information including an origin position mark which was read from an electrode drawing, a reference surface position is recognized, a processing range is set on the basis of the set origin position and figure information, the number of times of cutting is calculated on the basis of information regarding the process including the processing range and a cutting amount of the tool, and after that, the trace of the tool to be moved is determined on the basis of the information obtained so far. Since the reference surface position is automatically recognized, consequently, it is unnecessary for a human to form a drawing of the reference surface for the electrode drawing. The operation to decide the trace of the tool to be moved can be automated. <IMAGE></p> |
