PURPOSE:To decrease the number of times of replacement of a tool, by determining working sequence as prescribed and generating an NC program, when executing repeatedly >=2 times working of the same shape to the same work. CONSTITUTION:A sequence of a working process for working to a fundamental shape B0 is determined. Subsequently, the whole working sequence is determined in sequence for performing the i-th (i=1, 2...) working process for working to this fundamental shape B0, to all repeated shapes, and thereafter, performing the (i+1)-th working process of the fundamental shape to all the shapes in the same way. Based on this whole working sequence, an NC program is generated. In this way, the number of times of replacement of a tool in case of the repeated working (multiple working) can be decreased.
