In such a configuration, an example of the setting operation of the registered tool information SB will be described with reference to the flowchart of FIG. The operator operates the keyboard 27 of the input device 101 to display the display device 28.
To display the registered tool information setting screen (Step S10),
A desired tool is selected from the tool shape pattern indicated by the guide unit 25, and the tool shape code 20, which is the number displayed on the upper left of the selected tool shape pattern, is input to the keyboard 27.
Is set through (step S11). Then, the angles of the cutting edge angle 21 and the cutting edge angle 22 are set through the keyboard 27 according to the tool to be used (steps S12 and S13). For example, when the cutting edge angle is 55 degrees, the cutting edge angle 21 is set to “55”. Similarly, the projection 23 and the dimensions of the holder diameter 24 are set through the keyboard 27 according to the tool to be used (steps S14 and S15). For example, when the protrusion amount is 25 mm, the protrusion amount 23 is set to “25”. With the above operation, the setting of the registered tool information SB of one tool is completed. When setting the registered tool information SB of a plurality of tools, the above operation is repeated for the number of tools.

When the registered tool information SB is set in this way, the machining process generation unit 104 divides the machining shape data SA stored in the machining shape data storage unit 102 into machining shapes for each machining process according to an internal rule, and registers the registered tool information. With reference to the registered tool information SB stored in the storage unit 103, the used tool information of each processing step is determined, and the corresponding cutting conditions are further determined to generate the processing step SC. At that time, the machining process generation unit 104
