Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is an automatic programming method (hereinafter referred to as "auto programming") for a numerical control device that improves the operator's programming operation method.
automatically programmed:
(abbreviated as AP) method.

[Conventional technology]

A conventional AP system of this type is shown in FIG. In the figure, reference numeral 10 denotes an input unit for reading input information, etc., and information is input from a keyboard 30. 12 is an arithmetic unit that performs arithmetic processing based on the input information, and 14 is an output unit that outputs the arithmetic processing results of this arithmetic unit 12 to the outside, and stores software indicating the processing procedure of the arithmetic unit 12, processing results, etc. The storage unit 16 is also provided with a storage unit 16.

Here, the storage unit 16 is a ROM element, and the software 20 is stored in a RAM element and is memory guarded.
and a RAM element table 24 that is accessed based on this software 20. 32 is a paper tape output, and 34 is a printer.

Next, the operation will be explained. First, the operator inputs a program defined by the AP grammar of the software 20 from the keyboard 30. The input section 10 reads the information and stores it in the table 24 of the storage section 16 via the calculation section 12.

Generally, this program is composed of a large number of blocks, and the operator divides the blocks into individual blocks and inputs each block. When the operator has finished inputting a large number of blocks of programs, the program is then compiled and started to be converted into a program for a numerical control device.

At this time, the calculation unit 12 performs one-time compilation of the programs stored in the table 20 according to the processing procedure of the software 20 to create a program for the numerical control device, and stores the result in the table 20. Here, if an abnormality such as a grammar error in the program is found during compilation, the information is sequentially output to the printer 34 via the output unit 14.

When the one-time compilation is completed and no abnormalities are found, the operator starts outputting the program for the numerical control device, stores it in the table 24, and outputs the program for the numerical control device to the paper tape 32 via the output unit 14. do.

[Problem that the invention seeks to solve]

Since the conventional AP method is configured as described above,
P syntax errors and the like were not discovered immediately after inputting the program, but were discovered only after inputting the entire program and running a one-shot compilation. In addition, after live compilation, if you correct and input the found grammar errors and then re-compile, you are forced to perform live compilation from the beginning, which wastes compilation time.Also, input the program block by block. However, there were problems such as the psychological anxiety of the operator, which could not be ignored because there was no message.

This invention was made to solve the above-mentioned problems. When a program is input block by block, it is compiled each time, and the compilation results are output as regular information or temporary information, and grammar errors occur. It is an object of the present invention to provide an AP method for a numerical control device that enables early detection of problems such as the above, and also eliminates the operator's anxiety when inputting a program.

[Means for solving problems]

The AP method for a numerical control device according to the present invention includes an output section 11
Connect the C graphic display device and store it in the storage section 16.
By devising the software, the program becomes 1.
After inputting each block, it is compiled each time, and the calculation results are drawn on a graphic display device k, such as a straight line, 0 circular arcs, etc.

[For production]

In the AP method for numerical control in this invention, when a program is input block by block, the calculation results are
Since the images are drawn on a graphic display device, the operator can easily determine whether the program is correct or not.
Even if all the input information for the program is not available, it is drawn on the graphic display device as temporary information, so the operator can input the program with confidence.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, the same parts as in FIG. 10 are indicated by the same reference numerals. In FIG. a table 24 made up of RAM elements accessed by
A keyboard 30 is connected to the input unit 10 for inputting information from an operator. A paper tape output 32 for outputting calculation results and a graphic display 36 for drawing a trajectory etc. are connected to the output unit 14.Next, the specifications of this AP method for numerical control equipment will be briefly described. First, when the operator inputs the basic shape of one block from the keyboard 30 according to the AP grammar, the calculation results are drawn on the graphic display 36 each time.

In this drawing, the white drawing indicates data that is correctly defined and can be converted into a program for a numerical control device. Also, although the yellow drawing is correct information, the next command is incorrectly set or undefined, so it cannot be completely converted to a numerical control device program, so the next provisional information is created internally and drawn on the graphic display 36. This command requests the operator to input the next command, and if the correct next command is input, the drawing will switch to white. In addition, when drawing red, the input information is incorrectly set or not set, the incorrectly set or unset elements are internally created as temporary information, and the operator is requested to correct them. When corrected, the drawing becomes yellow or white. Next, a specific example of the drawing transition will be explained with reference to FIGS. 2 to 4. In Fig. 2 fal, the previous straight line command A
has been input, and input a new straight line command B (for example, the end point coordinate value), the straight line B from the end point coordinate value of the straight line command A
A yellow straight line is drawn up to the end point coordinate value. Next, when straight line command C is input, as shown in Figure 2 (b), the yellow straight line of straight line B is once erased (8) and redrawn as a white straight line, and then straight line C is drawn from the end point coordinate value of straight line command B. A yellow straight line is drawn up to the end point coordinate value. Next, when K and corner insertion D (for example, radius only) are input, the yellow straight line of straight line C is once erased as shown in Figure 2 (cl), and the straight line command or circular arc command after the corner insertion command is still set. However, the subsequent straight line temporary information is created internally, and the straight line C and the corner insertion arc are redrawn in yellow.

Next, when the straight line command E is input, the straight line C and the corner insertion arc are once erased as shown in Fig. 2(d), and the straight line command C
In response to the corner insertion command, the straight line C and the corner insertion arc recalculated using the straight line E are drawn in white, and furthermore, the end point coordinate value of the straight line E is drawn as a yellow straight line. As shown in Figure 2, normally, even if all the input information of the program is not available, temporary information is created internally and drawn in yellow, gradually approaching the normal trajectory drawing, and when all input information is collected, white is drawn as normal information. It is something that makes you

In addition, in Figure 3 (al), if the straight line command C is incorrect, provisional information of the wrong straight line is created internally, and a red straight line is drawn to indicate the incorrect setting. When corrected, the red straight line of straight line A is deleted as shown in Figure 3 (bl) and drawn as yellow straight line C. Figure 4 (
In at, when the already defined arc command B is modified, as shown in FIG.

As described above, if each trajectory is drawn on the graphic display and there are no abnormalities, the operator starts the program output for the numerical control device, converts the input data into data for the numerical control device, and outputs it to the output section 14. is outputted to the paper tape output 32 via.

Next, the operation shown in FIG. 1 will be explained. First, the operator inputs one block of program shape input defined by the AP grammar of the software 22 from the keyboard 30.

The input unit 10 thereby reads the information and stores it as a basic shape in the table 24 of the storage unit 16 via the calculation unit 12.

The data analysis of the basic shape is performed by the processing procedure of the software 22, which will be described later, to create graphic display data, and the result is drawn on the graphic display 36 via the output unit 14. Like this A
When the shape of P is input block by block, the graphic display 3 is displayed according to the processing procedure of the software 22.
6, and the operator is a person with a multi-shape program.

When the force is finished, the program output for the numerical control device is activated, the input basic shape is converted into a program for the numerical control device, and the paper tape output 3 is output via the output unit 14.
Output to 2.

Next, a table regarding the basic shape of the table 24 in FIG. 1 will be explained. In FIG. 5, the areas include a directory area A for managing the drawing state, an input area I for reading data from an input device, a basic shape area B for storing a large number of basic shapes, and a area used for data analysis calculations. There is a temporary area T. Directory-Area A
has the following: The number of registered shapes An stores the number of registered shapes in the basic shape area B. Number of trajectory completed shapes A
m stores the number of basic shapes (number of white drawings) that can be converted into a program for a numerical control device, and is used for graphic deletion and recalculation start number. The analysis start number A8 is a copy of the trajectory completed shape number Am. Input status indicates whether the input data is new data or modified data.
It is used to distinguish between In the case of new data, the input setting number Im is the latest shape number, and in the case of modified data, it is the shape number to be corrected. For input type Ii, the input data is straight line 1
It is used to distinguish between arcs, corners, etc. The input setting elements Idol to (k) are different data depending on each type; for example, in the case of a straight line type, they are end point coordinate values, etc. Basic shape area B has a basic shape with only the set order, mainly the input setting element Ie (kl is copied every time it is input, the shape number Iqzln is the input setting number In, type B (zlt is the input Type Ii is set to setting element B (tle(ol~(kl is input setting element)

A flag indicating whether to draw in white, yellow, or red; graphic elements 11) g(0) to (kl are information to be drawn on the graphic display (for example, in the case of a straight line, start point and end point coordinate values); Temporary area T is the area during basic shape analysis, and is the shape number from basic shape area B (Bft)n to graphic element t)〆k)
3 sets are copied in units of shape number T (oh to graphic element T (Q1g + kl). Analysis number Tn is the copy of analysis start number As, trajectory completion update flag Tn is trajectory completion Shape number Am
This is a flag that determines the update of . FIG. 6 shows details of each flag, and the bit correspondence is as follows. For example, input status I is assigned input completion, new data, and modified data, and type It-n(zlt, 'r
(A straight line 1 circular arc cw, circular arc CCW, corner R, and corner C are assigned to zli, and the drawing flag B (21f
, T(o)f are assigned drawing completion (white drawing), setting completion (yellow drawing), and shape error (red drawing).

Next, a processing procedure regarding basic shape input by the software 22 shown in FIG. 1 will be explained.

After this processing, branch to 5T-11. 5T-10 is En when input is completed) IJ-, the basic set here Based on the shape, it is compiled into a numerical control device program (NC data format) (data conversion) and output to the outside (paper tape output). 5T-11 is analysis start number A,
K"Number of trajectory completed shapes Am+1" (generally the previous yellow drawing number) is input, and the data analysis of the basic shape is not performed from the beginning, but is performed from the intermediate basic shape. Therefore, the time required for data analysis is considerably reduced compared to performing it from the beginning. 5T-12 is a graphic erasing routine that erases the graphic drawing from the basic shape (zl graphic element B(t)g(Of~(k)) according to the analysis start number As. 8T-i 3 erases the 6 basic shapes described later ' data analysis routine' performs data analysis of basic shape (t) using analysis start number As and graphic element B (1

After this, it branches to 5T-11A.

Since 5T-1OA has regular basic shape data and has no errors or unset settings, the drawing flag "drawing complete" is turned on to draw white. After this, it branches to 5T-12 people.

BT-11A passes when drawn using temporary information.

Here, turn off the trajectory completion update flag. As a result, data analysis is not performed from the beginning when inputting the basic shape next time, but is performed from the basic shape drawn using temporary information, thereby reducing the analysis time.

8T-12A is temporary T (Q), T (1)

5T-4B is a branch command that refers to the drawing flag T (0) f, and when there is 1 shape error, it branches to 5T-5B and draws red, and when 6 settings are complete, it branches to 5T-6B and draws yellow. When it is "drawing complete", it branches to 5T-7B and draws white. This process is performed by this software 22.
Even if the basic shapes are not aligned, temporary information can be created and drawn on the graphic display, and the operator can be alerted using colors.

5T-5B, 6B, 7B are respectively painted in red,
Graphic element T(olg(o
