<p>A method of preparing NC data, and particularly a method of preparing NC data by preparing macros (macros A, B, C, -----) that determine auxiliary data for machining (such as tools, the number of revolutions of main spindle, cutting speed, cutting conditions, or the like) in addition to the processing program (MNDP) for preparing NC data. The method of preparing NC data comprises: a step for interactively inputting at least data related to the shapes among the data required for preparing the NC data; a step for storing in advance in the memory (13) the processing program (MNDP) for automatically preparing the NC data using said data related to the shapes, and the macros (macros A, B, C, -----) that determine auxiliary data for machining required for preparing the NC data; a step for calling a macro that corresponds to said auxiliary data for machining in determining the auxiliary data for a predetermined machining; a step for determining the auxiliary data for the machining using said macro; and a step for preparing the NC data that perform the machining in accordance with a shape that is input by using said data related to the shapes and the auxiliary data for machining under the control of the processing program.</p> |
