Abstract
Abstract A prompt (MEQ) which indicates whether a machining end-point is (i) a point which coincides with a machining starting point, (ii) a point a predetermined amount Δα past the machining starting point, or (iii) a point a predetermined amount Δα short of the machining starting point is included on a dialog screen (DIM) and machining end-point information is entered from a keyboard (12). In response, a processor (11a) of a system main body (11) automatically computes coordinates of the machining from the machining end-point information, the machining starting point and path data, and creates NC data for arriving at the machining end-point along a path specified by the path data.
