〔Example〕

Next, one embodiment of the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, FIG. 2 is an overall flowchart showing the operation of the embodiment of FIG. 1, and FIG.
It is a partial flowchart figure which shows in detail the process operation of step 1008 called a mold|die allocation process in 70-chart of a figure.

In the example shown in FIG. 1, numerical control command information is created using figure information having coordinate values regarding the external contour information and internal hole information of the product and the mold 2 library information for the punch press to be processed. The storage device 1-1 to store the graphic information and mold library information is read from the storage device 1-1, the mold to be used is selected from the mold library information, and the graphic information is stored using this mold. A processing device 1-2 that creates and processes numerical control information for a punch press that processes external contours or internal hole shapes, a display device 1- that displays figure information, mold library information, and the locus of the punch mold. 4
, an input device 1-4 for instructing processing operations when creating numerical control command information, and a command tape output device 1-5 for outputting the created numerical control command information as a command tape.

FIG. 4 is a product shape diagram showing an example of a product processed in the embodiment shown in FIG. 1, where the outer contour is the coordinate value of each point P1 to P12, and the inner hole shape is the coordinate value of the point P101 to P108. It can be expressed as information. In addition, the mold library information includes the shape and shape of all punch press molds.
Contains information such as size and mold type.

The actual operation flow will be explained below with reference to FIGS. 2 and 3, taking as an example the graphic information of the product shown in FIG.

In response to an operation signal from the input device 1-4, target graphic information as shown in FIG.
1.1002), figures (without reference numbers in Figure 4)
is displayed on the display device 1-3 (step 1003).

Next, in the mold library information, specify the shape classification such as round, square, etc. Step 1004) Display all the molds having the shape code on the display device 1-3, and select the desired mold from among them. is selected (step 1005). Next, based on the displayed shape information, select the points of the external or internal shape to be processed as the starting and ending points (two point picks).
(Step 1006).

If the two specified points are the same point, the mode is set to 1 point mode, and if the points are consecutive points, the mode is set to 2 point mode, and the process moves to the mold allocation process (step 1007).

Other than this, for example, the designated point is reference number P1 in FIG.
If it is P3, it is assumed that the specified point is incorrect and the process returns to the process of specifying the machining point.

The one-point mode and the two-point mode then proceed to the operation flow shown in FIG. As shown in FIG. 3, in the one-point mode, the direction of the mold is specified. Mold information, for example, for a rectangular object, the short side x long side, that is, the longitudinal direction is 0° for the horizontal rectangular shape.
By defining this, the direction of 90° means a rectangular shape with the longitudinal direction being vertical. After this, as shown in Fig. 5, the offset amount (offset
, offset Y), the punch point Q is determined and a 1-piece machining code is generated.
It is displayed as the locus of the punch die on the displayed graphic information. If the bottle mark of the punch mold differs from the graphic information due to an error in inputting the offset amount, etc., the process returns to the input of the above parameters in the 1-point mode.

In the 2-point mode, input offset f for the starting and ending points of the dead body point. Offsera t't in this case
is the value that determines whether to lengthen or shorten the minute (machining length) connecting the start point and end point. FIG. 96 shows a column in which there is no offset amount for either the start point or the end point, and FIG. 7 shows an example in which a positive offset amount is given to both the start point and the end point.

(distance between the specified starting point and end point) + (offset t between the starting point and end point) e machining length, compare this machining length with (long side length of the selected mold 6
As shown in the figure, align the edge of the mold with the starting point and perform 1 punch, then align the edge of the mold with the end point and perform 1 punch 2.
Generate punch processing code. As shown in FIG. 7, if the machining length is large, a punching machining code (one machining code performs punching multiple times) is generated. Note that the direction of machining is determined by determining that the right side is to be machined when looking from the start point to the end point. Regardless of the external or internal shape, machining can be performed by specifying the start point and end point. Also, based on the generated machining code, the trajectory of the punch die is displayed and the input parameters are checked, as in the one-point mode.

The processing code group generated in this manner is converted into NC command information and sent to the designated tape output device 1-5, where it is output as an NC command tape.

FIG. 8 shows that according to this embodiment, NC command information was created for the internal and external shadow lines of the product shown in FIG. It is a diagram showing the state, ie, the trajectory of the punch die.

In this embodiment, an example is shown in which NC command information for all machining is created based on graphic information, but the present invention can also be incorporated into an automatic creation device for NC command information. For example, according to the present invention, it is possible to create NC command information of a figure shape portion that can be automatically created by the automatic creation device, that is, an unprocessed portion that cannot be automatically created.

〔Effect of the invention〕

As explained in detail above, the present invention calculates the machining reference point (punch start point) and machining length N based on the coordinate values of the graphic information.
By automatically converting to C command information, you can create NC command information without any knowledge or experience of NC programming, and you can read the figure information without making any mistakes and follow the trajectory of the punch die. Since the display also serves as graphical information, errors in input parameters can be checked and corrected in real time, NC command information can be created quickly and accurately, improving productivity in creating NC command information, and improving product quality. This has the effect of reducing costs.
