ード６のように黄色で表示される。(Example) Hereinafter, an example of the method for detecting mold interference according to the present invention will be described in detail with reference to the drawings. In FIG. 1, 1 is a black background on the CRTii&i surface, 2 is an upper mold, 3 is a lower mold, 4 is a workpiece such as a plate or pipe, and 5 is an interference part. Figures 2 and 3 are explanatory diagrams for drawing on a CRT screen, and when the screen uses eight colors, the graphic screen is blue (as shown in Figure 2).
There are three screens: red (second plane), and green (third plane). The planes are combined as shown in Figure 3 to display eight colors on the screen. The dot is displayed in yellow, such as color code 6.

Ａ、Ａ＋Ｂ≠Ｂ、、Ａ−Ｉ−Ｂの色を使用する。In the above configuration, the case where two colors are used for operation will be explained next with reference to FIG. In step 11, the mold is drawn in color A on the CRT screen. Next, in step 12, the bent workpiece is drawn in B color on the C' RT screen. In step 13, it is checked whether there is a part that has the colors A and B. Step 14 if there is a part with the color A + B in step 13
If there is no interference, go to the non-interfering direction in step 15. However, in this case, A+B=l'=

細かく判断できる。In this method, in the embodiment shown in FIG. 1, the upper die 2 and the lower die 3 are drawn in red, and the workpiece 4 after bending is drawn in green, as shown in FIG. 5. When combined, the color of the area where the mold 2.3 and workpiece 4 interfere as shown in Figure 1 is red, ten green = 010 + 100 =
110, and is represented in yellow. This shows that there is a location where there is interference. Further, in addition to the above example, by drawing each mold in several colors and further drawing the workpiece after bending in several colors, it is possible to finely determine the location of interference.

干渉をＣＲＴ画面上で描画するようにしたため、
（１）複雑な方程式を解く必要もなく、プログラムが簡
単になる。(Effects of the Invention) As explained above, according to the present invention, since the interference between the mold and the workpiece is drawn on the CRT screen, (1) there is no need to solve complex equations, and the program is simple; become.
（２）形状を描画すると、どんな？ＪｌＩＩＩな被加工
物でも干渉を検出出来る。(2) What does it look like when you draw the shape? Interference can be detected even with JlIII workpieces.
（３）干渉検出に要する時間は描画時間＋干渉部分探索
時間で、短時間で検出が可能である。(3) The time required for interference detection is the drawing time + interference portion search time, and detection can be performed in a short time.
（４）描画メモリのみで干渉が検出出来る。(4) Interference can be detected using only the drawing memory.
