In addition, the load model shape creation section 6 receives the cutting amount component of the cutting edge load obtained from the machining data 1 by the cutting amount analysis section 3, and the machining processing via the function generation section 4 and the cutting speed analysis section 5. The speed component of the cutting edge load determined from data 1 is input, and the magnitude of the cutting edge load model is determined by these two components. The cutting edge load model CM whose shape and size have been determined is displayed as shown in FIG. 2B, corresponding to the starting position of the cutting edge in FIG. Furthermore, the material erasing control unit 8 collects tool shape data,
By using the position data calculated from the machining data 1 by the function generator 4, the machining completed portion to be removed by cutting etc. from the previously drawn material is erased as shown in FIG. 2C. A material processing completion screen is created, which allows you to see the processing status of the material.

点がある。 As described above, according to the method of this invention, in addition to the trajectory of the tool and the shape of the completed part of the material, you can also see at a glance the load condition on the cutting edge that changes depending on the depth of cut and cutting speed, which was not displayed previously. This allows the operator to stop machining that could potentially destroy the tool, or to improve the machining data so that it does not place excessive stress on the cutting edge by correlating the machining data with the load on the cutting edge. This has the advantage of being possible.
