。Numerical control information 1 for performing machining simulation is read by the reading/analysis section 2;
extracts the interpolation command Ic and the feed rate command Fc from the numerical control information l and transfers them to the interpolation calculation section 3 (step Si). The compensation calculation unit 3 performs interpolation calculation based on the interpolation command 1c and the feed rate command Fc to determine the tool cutting edge position T.
To calculate p, step S2), this tool cutting edge position 'rp
is transferred to the material shape drawing section 4, tool shape drawing section 5, and tool trajectory drawing section 6. Note that the material shape drawing section 4. The tool shape drawing section 5 and the tool trajectory drawing section 6 each have a keyboard 9.
The display area Ac is set via the. Here, the material shape drawing unit 4 compares the tool edge positioner p received from the interpolation calculation unit 3 with the display area Ac preset on the keyboard 9 (step S3), and the tool edge position Tp is displayed. In the state inside the area ^C, the part to be scraped off of the material is recognized sequentially from the previous tool cutting edge position and the current tool cutting edge position Tp, and the cutting part of the material is recognized as shown in the shaded area in Fig. 5 (A). Drawing information Wi is generated and transferred to the display control section 7. Further, if the tool edge position Tp received from the interpolation calculation unit 3 is inside the display area Ac, the tool shape drawing unit 5 generates tool shape drawing information Ti as shown in FIG. 5(B). and transfers it to the display control section 7. Similarly, the tool path drawing section 6
If the tool cutting edge position Tp received from the interpolation calculation unit 3 is inside the display area AC, the tool movement trajectory is recognized from the previous tool cutting edge position and the current tool cutting edge position Tp, and as shown in FIG. Generate tool trajectory drawing information Lj as shown in (C) and transfer it to the display control unit 7 (steps S3 and S4)
Then, the display control unit 7 synthesizes the above-mentioned material shape drawing information W+, tool shape drawing information TI, and tool trajectory drawing information Li, and displays a graphic on the graphic display device 8 as shown in FIG. (Step S5)

することができない欠点がある。(Problem to be Solved by the Invention) In the display system as described above, consider a case where c is set to be smaller in the display area than the shape of the material, etc., as shown in FIG. In this case, even if the tool cutting edge position Tp exists outside the display area AC, the interpolation calculation unit 3 performs interpolation calculation according to the feed rate command Fc in the numerical control information 1.
Therefore, even if the operator attempts to locally display graphics by setting the display area AC small, wasteful interpolation calculations as shown by the broken lines will be performed outside the display area Ac, and the numerical control will be quickly interrupted. There is a drawback that information l cannot be checked.

The above-mentioned object of the present invention is to perform an interpolation calculation from the interpolation command and the feed rate command in the numerical control information to calculate the tool cutting edge position for displaying the tool shape and tool trajectory. Each time an interpolation calculation is performed, the calculated tool cutting edge position is compared with the display area, and it is determined whether the displayed tool shape and tool trajectory are outside or inside the display area. This is achieved by increasing the feed rate used for interpolation calculations.
