Afterwards, the code G menu display, code G selection, detailed image display and NC data generation processing are repeated to generate a desired part machining NC program.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an NC program creation method for interactively creating an NG program, and particularly to an NC program creation method that allows even beginners to easily create a NG program.

<Prior Art> NC machine tools perform desired processing on a workpiece by operating according to instructions on an NC tape prepared in accordance with ISO or EIA standards. In this NC tape, numerical data that defines the movement of the tool is input according to predetermined rules, and data necessary for machining such as feed rate, G code, M-, S-, and T-function commands are inserted in appropriate places. Created. By the way, in creating such an NC tape, it is difficult to use the G code and how to give numerical data when specifying the G code, and considerable programming skill is required. In particular, if there are many G codes used, all G codes
Even experienced users may find it difficult to remember the function of the code and how to command the G code in what situations, and may end up programming while looking at the instruction manual, making programming tedious and time consuming. There is. Such defects become more noticeable as the shape of the workpiece becomes more complex.

For this purpose, tool motion and machining conditions are defined using automatic programming Mm, and then EIA or ISO
Automatic programming devices are now being used that convert the code into NG programs. With this automatic programming device, it is possible to easily and effectively program even complex shapes without making any mistakes.

Since programming is easy and can be done in a short time, the NC device has been equipped with the function of an automatic programming device, and an NC device with an automatic programming function, which can perform automatic programming in parallel with NC processing, has been put into practical use. has been done.

<Problems to be solved by the invention> However, adding an automatic programming function makes the NC device more expensive. For this reason, a simple NC device with a programming function aimed at low cost cannot be provided with such a high-grade automatic programming function. In other words,
Low-priced and simple NC devices with programming functions are still failing based on direct EIA codes, etc.
There is a problem in that a program has to be created, making programming troublesome, requiring a long time to program, and having a high probability of programming errors.Furthermore, programming can only be done by a highly skilled person.

From the above, the purpose of the present invention is to prevent even beginners from making mistakes (EI
It is an object of the present invention to provide an NC program creation method that can create an NG program using A code or the like.

Another object of the present invention is to display on a display screen an image indicating the function of the G code and what data must be input when executing the function of the G code when creating one block of NC data. An object of the present invention is to provide an interactive NC program creation method that allows reference to be made to create NC data.

A detailed image corresponding to the code is displayed as appropriate, and data is input from the data input section 104b by referring to the image.
NC data is created block by block.

When creating NC tapes directly using EIA codes, etc., the reason why it is difficult to create even relatively simple NC programs such as NC programs for lathes is because of the functions of various G codes and the predetermined G codes. The problem is that the method of giving numerical data when specifying is not recognized. In other words, programming becomes difficult for beginners because they cannot understand all of the G code, and even experienced users have to refer to the instruction manual every time.

Therefore, if an image related to the G code is displayed when creating one block of NC data, and data can be input while referring to the image, even beginners can easily program. Programming can be done easily and in a short time without the need to look.

Therefore, in the present invention, a detailed image of each G code is stored in memory in advance in correspondence with the G code, and when programming is started, a G code menu is displayed on the display screen, and the displayed G code is displayed. 1 to be created from the code menu
Select a G code related to the NC data of a block, read the detailed image of the selected G code from the memory and display it on the display screen, and refer to the detailed image of the G code to read the NC data of one block. After that, the process of displaying a G code menu, selecting a G code, displaying a detailed image of the G code, and creating one block of NC data is repeated to create a desired NC program for machining parts.

Returning to FIG. 1, although not shown, the axis control unit 106 has a pulse interpolator and a servo unit for each axis, and the pulse interpolator receives the amount of movement of each axis per unit time from the processor 101, Based on the pulse interpolation calculation, distribution pulses are generated and input to the servo unit, and the servo unit executes well-known servo control based on the input pulses.

The interface 107 outputs M+, S-, T- function commands and the like issued by the processor 101 to the machine tool 201, and inputs various signals from the machine to the processor.

Below, the interactive NG program creation method of the present invention will be explained with reference to the flowchart shown in FIG. 3 and the CRT drawing example shown in FIG.

(1) Use the mode selection switch (not shown) on the operation panel 108 to set the edit mode, and
Among the function keys of the I device 104, PRGRM
Press a key. As a result, the initial image shown in FIG. 4(A) is displayed on the CRT screen. Note that if a program has already been registered, the program will be displayed on the screen in, for example, EIA format. Hereinafter, the explanation will be given assuming that the program is not registered.

(2) Next, enter the program number of the program you want to newly register after the word address MO and press CRT&MD.
Enter using the alphanumeric keys ENK of the I device 104 (the alphabet O is a word address word indicating that the following numeric value is a program number). for example,
If you want to register program number 10, 0
After pressing the 1o key, press the EOB key.

(3) After entering the program number, press soft key SK5 and enter "interactive".
), the G code menu is displayed. Furthermore, G
The code menu is a menu image showing the correspondence between various G codes and their functions.

(4) While the G code menu is displayed on the CRT screen, the G corresponding to the function programmed)-)
Enter the code using the alphanumeric keys ENK.

For example, if you want to perform positioning, when you look at the G code menu, you will see GOO, so you will manually key GOO.

Incidentally, if the desired function to be programmed is not displayed on the current screen, press the page key PGZ to display the next G code menu. Then, these operations can be repeated until the desired function appears. Also, unless the function to be programmed is a G code, no key input is required.

(5) After inputting the G code, press the soft key SKI to input "menu", and the detailed screen of the G code input in the previous step will be displayed on the CRT screen. FIG. 4(C) is an example of a detailed image of the G code GOO. This detailed image is (a) G
It has a first image part GIM1 that shows the function of the code and what data should be input, and a second image part GIM2 that shows one block of NC data consisting only of word addresses with (bl numerical data blank). .

In addition, if no key has been input in the previous step,
Upon inputting the 'menu', a detailed image in standard EIA format is displayed as shown in FIG. 4(D).

(6) While the detailed image shown in Figure 4 (C) or (D) is displayed, move the cursor C8R on the CRT screen by operating the cursor key C81 or C32 to the word address of the required data. let It should be noted that each time the cursor key C32 is pressed, the cursor C3R is shifted to the right by one address word, and when there is no address word in the corresponding line, it is shifted to the first address word in the next line. Further, if the cursor key C81 is pressed, the cursor C3FL moves in the opposite direction to that when the cursor key C32 is pressed.

When the cursor C3R is positioned on the desired word address word, the word address word will blink, then press the alphanumeric key ENK to input numerical data, and press the INPUT key every time one numerical data input is completed. Press. Then, enter the necessary numerical values in the same way. FIG. 4(E) is an example of CRT drawing after inputting all necessary data.

(7) While the image in Figure 4 (E) is being drawn, press the lN5ERT key to display one block of NC.
Data is registered in RAM 103.

(8) After printing, check whether the creation of the desired part machining NC program has been completed.

(9) If the creation of the N C program has not been completed, press the soft key SKI and input '°G, many '°. This will display the G code menu shown in Figure 4 (B) on the CRT screen. Then, the process from step (3) onwards is repeated.

(On the other hand, if the creation of the NC program for machining the desired parts has been completed, press the soft key SKO. The program is drawn on the CRT screen in this format.The program can be started by pressing the RESET key.

Once the NC program is created as described above, the operation panel 10
The constant memory operation mode is selected using the mode selection switch 8, and then the NG control is executed using the NG program.

Although the above explanation assumes that G code G00 is selected in step (4), when the linear interpolation GOI is selected, the detailed image of Gol shown in FIG. 4(F) is drawn on the CRT screen. . When programming linear interpolation with overcutting, chamfering and corner radius blocks can also be programmed at the same time. That is, when the detailed image of linear interpolation (see Fig. 4 (F)) is displayed, if you press soft key SK4 and input "chamfer", the chamfer block shown in Fig. 4 (G) will be displayed. Since a detailed image of the linear interpolation with chamfering is displayed on the CRT screen, by referring to the image and inputting the necessary data manually, it is possible to create the NC data of the linear interpolation block with chamfer. Similarly, it is also possible to create NC data for a linear interpolation block with rounded corners.

Further, although the above is an NC program creation process, it is also possible to call up an already created and registered NC program and check its contents, or to import, delete, or change NC data in units of blocks.

For example, if you want to check an NC program that has already been registered, perform the following operation. That is, press the PRGRM key, which is a funk key, and then input the program number you want to confirm by pressing the alphabet O followed by the key. This will display the NC program in EIA format on the CRT screen, so press cursor C3.
When 2 is pressed, the program image changes one block at a time and is displayed. FIG. 4(H) is an example of a program image including a program end.

Then, after moving the cursor to the beginning of the block you want to confirm by operating the cursor keys, press soft key SK5 and input "interactive", the screen will be converted to an interactive screen with the contents of the block, and the fourth screen will be displayed. The screen is displayed as shown in Figure (I). The image drawing procedure shown in FIG. 4 (1) is as follows: (The al processor 101 determines the G code of the block indicated by the cursor, and (b) After drawing, the image corresponding to the G code is stored in the ROM 10.
(C) Word address: i (X, Z) and the blank part following the block contains the numerical value (100°200
).

Moreover, although the present invention is applied to an NC device with a programming function, the present invention is not limited to such a case.

<Effects of the Invention> According to the present invention, the G code is preliminarily associated with each G code.
A detailed image of the code is stored in memory, and when programming starts, a G code menu is displayed on the display screen, and from the displayed G code menu, the G code related to one block of NC data to be created from now on is displayed.
Select a code, read out the detailed image of the selected G code from the memory and display it on the display screen, create one block of NC data by referring to the detailed image of the G code, and then use the G code menu Since the configuration was configured to create the desired parts machining NC program by repeating the display, G code selection, display of the G code detailed image, and 1 block NC data creation process, the G code function and G code were specified. You can recognize the data that should be entered at the time just by looking at the screen, so even beginners can easily enter ET without making mistakes.
NC programs can be created using A codes, etc., and the time required for programming can be further shortened.
