<p>A method of preparing an NC part program for numerically-controlled machining includes a plurality of machining steps, e.g., a first machining step for machining workpiece (WK) into a roughly-machined shape (P5-P4-P3-P2-P1), and a second machining step for machining the workpiece into a finished shape (P6-P7-P8-P9-P10). The method comprises: inputting, for each machining step, at least the tool to be used TL1, TL2, the axial incremental quantity between a reference position (R) on a tool slide (TBS) and the end of the tool used, and positions (P5 to P1; P6 to P10) to be machined; preparing a subprogram for each machining step by employing these items of data; preparing a main program for calling the subprograms in the order of machining step; and combining the subprograms and the main program to prepare an NC part program.</p> |
