The coordinate position of the * mark is calculated from the value of -2,000 ". The coordinate calculation of the * mark is obtained by the following formula: * The X coordinate of the mark = the absolute coordinate X + the remaining movement amount X = 50.000 + (-2 .000) = 48.000 * Z coordinate of mark = absolute coordinate Z + remaining movement amount Z = -8.511 + 11.511 = 3.000 The coordinates of * mark are obtained by the above method and stored in the bitmap memory for animation drawing. As a result, the * mark will be displayed at the position of arrow A on the program check screen.In Fig. 3, the * mark will be displayed at the position of arrow B on the screen by performing the same calculation as above. The operation described above is performed in the flowchart of FIG.
This corresponds to the calculation in steps S1 and S2. Then, in steps S3 and S4, a change in the tool is determined, and in step S5, the calculated destination data is added to the conventional drawing data, and drawing is executed (step S5). In this embodiment, the destination end point is displayed as *
Although the symbols are used, the present invention is not limited to this, and any symbols including characters can be used as long as they do not normally appear on the program check screen at the time of processing and interference check. The machining program used in this embodiment is not limited to the interactive program, and may be NC data created by manual input. FIG. 5 shows an offset value selection display screen according to an embodiment of the present invention as claimed in claim 2, where O is an offset number, and P and Q are offset values stored corresponding to the offset number. Is. Further, R displayed at the bottom of the screen is a menu that can be selected by a soft key. By pressing the soft key corresponding to the menu "select / cancel", first, the offset number is selected and canceled. When you select an offset number, * appears to the left of the selected offset number.
A symbol (see arrow S) is added. Then, by pressing the soft key corresponding to the menu "selection display", only the selected offset number and offset value are selectively displayed. That is, it is left on the screen. The selected and displayed state is shown in FIG. The symbol T in the drawing indicates the cursor position. In this way, the user can delete the unnecessary information from the screen by reselecting the offset number assigned to the offset value to be rewritten, so the offset value is selected on the screen. At this time, the cursor T moving operation can be reduced, and the offset value can be easily rewritten. In addition, it is possible to solve the problem that the offset value corresponding to the offset number is mistaken due to the reduced amount of displayed information. By pressing the soft key corresponding to the menu "selection display" again, it is possible to return to the display contents of FIG. However, even if the display state is returned to, the contents of the selected offset number are not canceled.

FIG. 9 is a diagram for explaining a method of determining the automatic scaling factor for animation drawing according to an embodiment of the present invention of claim 4. As shown in FIG. 9, when the material shape (work) is defined, the drawing magnification is determined by the following method using two settings of N and M.

## EQU00001 ## Xbairitu = Ydot / (Hankei
X (N + M))

## EQU00002 ## Zbairitu = Xdot / (Nagasa
× (N)) Hankei: Maximum radius combining nail and work Nagasa: Length combining nail and work Xdot: Dot of viewport X coordinate (horizontal direction)
Number Ydot: dot of viewport Y coordinate (vertical direction)
Number N: Setting the magnification above the center of the spindle and in the machine Z-axis direction (X coordinate direction on the viewport) M: Setting the magnification below the center of the spindle That is, N and M have the following meanings. Meaning of N and M <Radial direction> N: When the maximum radius of the combination of the claw and the work is set to "1", the setting is to display N times "1" above the center of the spindle. M: When the maximum radius of the combination of the claw and the work is set to "1", the setting is to display below the center of the spindle by M times "1". <Length direction> N: When the maximum length of the combination of the claw and the workpiece is "1", the length direction is displayed by N times "1". Xbairitu: Mechanical X-axis direction magnification Zbairitu: Mechanical Z-axis direction magnification The smaller one of Xbairitu and Zbairitu obtained by the above equation 2 is adopted as the drawing magnification. FIG. 10 is a diagram for explaining a method of determining the automatic scaling factor for animation drawing according to an embodiment of the present invention of claim 5. Figure 10
If the material shape is not defined as shown in, NC
The stroke setting of the parameter is read and the drawing magnification that can display the full stroke in the X and Z directions is determined.
Hankei of (Equation 1) and Nagasa of (Equation 2)
With Hankei = ((+ X stroke)-(-X stroke)) / 2 Nagasa = (+ Z stroke)-(-Z stroke) In this case, the processing origin is virtually regarded as the center of the full stroke. Also, since there is no definition of the material shape, the work is not trimmed, and the drawing mode is automatically changed to the tool path only. It is not necessary to change the drawing magnification according to the dimensions of the material used, and the display area can be used effectively. (The area below the center of the main axis that is not drawn can be minimized.)
Also, by setting the setting "M" to "O", it is possible to draw only above the center of the main axis without adding an algorithm.

As is apparent from the above description, according to the present invention of claim 1, since the program check screen is provided with an animation drawing and a symbol display of the moving destination end point of the tool, it is unfamiliar with NC sentence decoding. It has the advantage that even beginners can easily perform processing and interference checks. Further, it has an advantage that a user who is familiar with NC sentences can perform more accurate program check. Also, the present invention of claim 2 has an advantage that the offset value can be easily rewritten without making an input error because it has a configuration for selectively displaying only the offset value to be rewritten. ing. Further, claim 3
The present invention has the advantage that a part of the foreground information can be displayed on a part of the background display screen at the same time, so that the status during the machine operation of the foreground can be confirmed even during program creation by the background. Further, the present invention according to claim 4 has an advantage that the display area can be effectively used since the drawing is performed by making the enlargement of the half portion centering on the axis of the combination different from the enlargement of the remaining half portion. The present invention according to claim 5 provides X within a predetermined range.
Since the half-magnification in the direction is drawn differently from the remaining half-magnification, the tool path of the NC sentence can be displayed without defining the material shape.
