Abstract

PURPOSE:To shorten the time of checking work by discriminating the bite of a tool in component shape by detecting the fact that the tool on a display picture is superposed on the component shape, and performing alarm display. CONSTITUTION:First of all, colors to plot raw material shape 3, the component shape 4, and the tool 2 are set, for example, at a green color for the raw material 3, a blue color for the component shape 4, and a red color for the tool 2. And when the red color of the tool 2 is superposed on the blue color of the component shape 4 on a picture by the movement of the tool 2, or when the color of a background is superposed on the blue color of the component shape 4, it is judged that the bite is generated. In such a case, it is decided whether or not a logical product at the same coordinate position on the picture of a frame memory of red color and the frame memory of blue color goes to '1', or whether or not the storage of the coordinate position stored in the frame memory of blue color is erased. And when it is judged as 'YES' by the above decision, the alarm display is performed 8 on a screen. In such a way, it is possible to shorten the checking work.

If the color of the tool overlaps with the color of the part shape, or if the background color and the color of the part overlap, it is determined that tool digging has occurred and an alarm is displayed on the screen.

〔実施例〕〔Example〕

以下、本発明の一実施例を図面に基づいて説明する。 Hereinafter, one embodiment of the present invention will be described based on the drawings.

。２ａは工具の刃先であり、赤色で塗り潰されている。FIG. 1 shows an example of a display screen when checking the NC program of the present invention. In the figure, 1 is a display screen. 2 is a line indicating the tool shape, which is drawn in red. 2a is the cutting edge of the tool, which is filled in red.

It is drawn with a blue line. 5 indicates the chuck shape.

６は刃先の移り１軌跡を示し、７０点線で示される範囲

ように選んで設定する。本実施例では、素材形状には緑
色、部品形状には青色、工具には赤色を設定しである。Next, the operation will be explained. First, colors for drawing the material shape, part shape, and tool are selected and set to be different from each other from among the three primary colors used to display the color screen, that is, green, blue, and red. In this embodiment, the material shape is set in green, the part shape is set in blue, and the tool is set in red.

このようにすることによって、素材形状、部品形状及び
工具を描画する一画面の色のフレームメモリはそれぞれ
互いに独立して設定されたことになる。By doing this, the frame memories of one screen color for drawing the material shape, part shape, and tool are set independently from each other.

らばその部分は背景色に塗り変える。Then, each shape is drawn on the screen, and the tool on the screen is moved according to the commands of the NC program. If the red color of the tool overlaps with the green color of the material shape on the screen as the tool moves, that part is repainted with the background color.

る。Judgment of color overlap is made as follows. That is, the determination is made by performing the logical product of the same coordinate locations on the screen of the red frame memory in which the tool is drawn and the green frame memory in which the material shape is drawn. The logical product is rlJ
If so, it is determined that they overlap. Then, delete that coordinate location from the green frame memory. Therefore, that part becomes the background color. The portion that is colored as a background color by this determination is essentially the portion that is considered to have been cut by the tool, and this portion is indicated by 7 in FIG.

工具の移動により、画面上で工具の赤色と部品形状の青
色が重なった場合、又は背景色と部品形状の青色が重な
った場合はくい込みが生じたと判断する。If the red color of the tool overlaps with the blue color of the part shape on the screen due to the movement of the tool, or if the background color and the blue color of the part shape overlap on the screen, it is determined that a bite has occurred.

された場合には、画面上にアラームを表示する。In this case, the logical product of the red frame memory and the blue frame memory at the same coordinates on the screen is 'LJ
The determination is made based on whether or not the coordinate location has been erased from the blue frame memory. If fYEsJ is determined based on this 'R11 constant, an alarm is displayed on the screen.

It disappears. Therefore, the time required for checking can be shortened and the burden on the operator can also be reduced.
