Abstract

PURPOSE:To attain the smooth and easy control of an NC (numerical control) program by writing both program numbers and names to a directory and displaying them in each prescribed order. CONSTITUTION:Plural NC programs are registered to a bubble memory device 7 for an NC device 3 which controls a machine tool 1. The control information on those programs are stored in a program number directory file 45 and a program name directory file 47 respectively. When the directory display processing is indicated by an operating device, the directory files are opened. Then three display modes, i.e., the program number order, the program name order and the program number/name order are carried out selectively through decision of parameter. Then the directory files are closed and the control processing is through.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for managing programs used in an NC device.

[Description of the Prior Art] Conventionally, NC tapes are processed within an NC device under the concept of files, and are generally managed using a four-digit program number following an address code O.

Therefore, the program number assigned to each file can be displayed as a directory, for example, in descending order of value (ascending order), and a predetermined program can be designated by the number.

Therefore, when accessing a program, the NO operator observes the program numbers displayed in the ascending order,
A desired program can be specified.

However, the display of the above program is a numerical value, and it is not possible to know what kind of program it is just by observing this number. When searching for a program, you must first check the corresponding number in the ledger and find the desired one. It was difficult to search for programs. In particular, recent FMS
With this trend, the number of NC tapes continues to increase,
With conventional program management methods such as those described above, it has become increasingly difficult to search for and specify programs.

Therefore, there are examples in which programs are given names using not only numbers but also alphabets, so that when displaying directory files, the names can be displayed as well as the numbers. Nowadays, even if numbers are displayed with names attached to them, it is difficult to find the desired program from a large number of programs displayed in ascending order of program numbers. Management was still difficult.

[Object of the invention] The object of the present invention is to provide a program management method that can improve the above-mentioned problems and smoothly and easily manage a large number of programs that are increasing due to the FMS trend. shall be.

[Summary of the Invention 1 In order to achieve the above object, the present invention provides an NC program management method in which a program number and a program name are written together in a directory for one NC program, and the program is managed by the program number or the program name. By displaying the program name in ascending order from both sides, management can be performed from both the program number and name.

The MDi vN device 41 can input NC programs and other NG device operation information, and can also perform display operations related to the CRT 39 and operations related to file management of the bubble memory 7b. paper tape reader 43
You can also input data using paper tape. The configuration is such that a predetermined program can be registered in the bubble memory 7a by inputting it on a paper tape or by the program creation operation of the MDi device 41 so as to manage files in a directory.

When registering a program in the bubble memory 7a, the input operation is performed from the paper tape reader 43 by punching a program number with a 4-digit address following O on a paper tape, for example 01111, and then typing this program number and 1. : Program name within 16 characters corresponding to 1,
For example, AA...AA is punched, and the division is input after punching an extension for grouping the NC tapes through symbols (separators) and program contents. The extension is used to group programs, for example, when writing programs of the same group in a directory or deleting programs of the same group from the directory.

A detailed diagram of the bubble memory 7 is shown in FIG.

The bubble memory 7b includes a directory file 45 by program number having a program number storage part 45a, a program name storage part 45b1 and a start address pointer 45c, and a directory file 45 by program name having a program name storage part 47a1, a program number storage part 47b and a start address pointer 470. A directory file 47 and an NC tape image 49 that stores programs specified by the start address pointers 45c and 47C.
It consists of and.

In the program number directory 45, a program number and a program name are written in correspondence with each other in one file, and the program numbers are arranged in ascending order from the smallest value to 1111°2222.3333...
The numbers should be listed in the following order, and the MO+ device 41
This list status can be displayed in response to a call for display by program number from .

On the other hand, in the directory file 47 by program name, a program name and a program number are written in correspondence with each other for one file, and the ascending order of the program names is alphabets A and B.

C... order, that is, AA...AA, BB...8B
,・・・・・・・・・,XX...XX,YY...Y
The programs are listed in an order such as Y, and the list status can be displayed in response to a call from the MDi device 41 for displaying by program name. The calling method will be explained in detail below in FIG.

The start address pointers 45c and 47C of each directory file 45, 47 are designed to independently specify the corresponding program of the NC tape image 49. The file designation from each start address pointer 45c, 47C is indicated by a dashed dot line ■ in FIG.

■, ■, ■ and chain lines (A, B, X with circles).

Y). One point 1ilJI! As shown in, for example, the program PIX specified by the start address pointer 45c of the program number-specific directory file 45 with the program number 1111 is the program P+ specified by the start address pointer 47C of the program name-specific directory file 47. Matches X. Other programs P5A, P3B, P shown in Figure 3
For 2Y, both start address pointers 45C, 4
You can specify the same from 7C.

Regarding the directory files 45 and 47 shown in FIG. 3, in this example, whether to display them by number or by name can be specified by a parameter. That is, for example, if the parameter code is 1.2.3. In code 1, the directory is displayed in the order of program numbers, and code 1 is set as the default. In the default state, only display by program number is possible as before. and,
Code 2 should display the program name,
In addition, in code 3, by operating keys on the MDi device 41 (see Figure 2) to display both program number order and program name type, it is possible to display ascending order by number or name type as desired. It is selectable.

Next, details of the directory display will be explained using FIGS. 4 to 7.

4 to 7 are processing flowcharts regarding directory display.

Figure 4 shows an overview of the display function.

As shown in FIG. 4, when there is a directory file oven input signal in step 403, step 405
Then, the parameters at that time are determined.

Steps 407, 409. 411 indicates a display processing subroutine; if code 1 is determined in step 405, the process moves to step 407; if code 2 is judged, the process moves to step 409; and if code 3 is judged, the process moves to step 411. Move. As will be described later, in step 407, program number order is displayed, in step 409, program name type is displayed, and in step 411, program number order and program name type are displayed in combination, as detailed in FIG. It will be done.

In step 413, the directory file is closed in response to the display work end signal, and the directory file is closed and the display work is ended in step 415.

FIGS. 5 to 7 show step 407 in FIG. 4, respectively.
409. It is a detailed explanatory diagram of the routine shown in 409.411.

Details of step 407 (display routine by program number) shown in FIG. 4 are shown in FIG.

Step 501 is for determining the end of the file.

Then, step 50 unless it is determined that the file has ended.
Move on to 3.

Step 503 is to read the directory file classified by program number indicated by reference numeral 45 in FIG. 3 for the number of program codes. Then, in step 505, the file corresponding to the code read in step 503 is displayed on the CRT 39 (see FIG. 2). These reading and display processes are performed sequentially in ascending order of program numbers, and step 50
If it is confirmed in step 1 that the display of all programs has been completed, the routine is exited, the directory file is closed as shown in step 413 in FIG. 4, and the display process is ended.

As shown in FIG. 6, step 409 shown in FIG.
The details of the (program name type display routine) are shown in FIG.

Step 601 is for determining the end of the file.

Then, step 60 unless it is determined that the file has ended.
Move on to 3.

Step 603 is for reading out the directory file classified by program name, indicated by reference numeral 47 in FIG. 3, for each code. Then, in step 605, the file corresponding to the code read in step 603 is displayed on the CRT 39. These reading and display processes are performed sequentially in the alphabetical order of R (in the order of A, B, and C), and step 6
If it is confirmed at step 01 that the display of all programs has been completed, the routine is exited, the directory file is closed as shown in step 413 in FIG. 4, and the display process is ended.

Details of step 411 (combined display routine) shown in FIG. 4 are shown in FIG.

Step 701 shows a key operation on the MDi device 41 shown in FIG. 2, and is a selection operation of whether the MDi device 41 displays programs in order of number (A) or program names (B). It can be carried out.

If the program number order display (A) is selected in the MDi device 41, the process moves to terminal A and the program number order display routine shown in FIG. 5 is entered. On the other hand, MDi device 4
If the display of program names (B) is selected in step 1, the terminal B is moved to proceed to the program name display routine shown in FIG.

In addition, when displaying programs in order of number or program name, the name can be written together with the number order display, or the number can be written together with the name and type display, but this combination is shown in Figure 5. The display method described in FIG. 6 can also be used. Furthermore, the display method described in FIGS. 5 and 6 cannot be used, but it can be performed only in the method shown in FIG. 7.

In the directory display method described in FIGS. 4 to 7, it is assumed that the NC operator wants to search for programs with names AA...AA. In practice, this name is usually given by a meaningful name indicating the work content, such as TPN15 (meaning nibbling work number 15 of a turret punch press), or other customer content. It should be noted that this is very different from meaningless consecutive numbers.

Therefore, the NC operator should use the display method shown in FIG. 6 or the display method shown in FIG.
By operating the device 41, program names can be displayed in ascending order.

Then, a large number of programs with respective names are listed in the order of A, B, and C on the CRT 39.

Therefore, the NC operator can easily search for AA...AA (TPN15) from among the displays listed in ascending order and can immediately know the program.

Note that here, the NC operator can specify the program by specifying the name, and from then on, the program can be managed using only this program name, but conventionally, program management has mainly been , it is customary to use a program number. Therefore, in this example, as shown in FIG. This can also be done when displaying program names. By writing this together, it is possible to display, search, designate, etc., and manage the information by number or name as appropriate. Of course, it is not necessary to write them together.

In the embodiment described in detail above, it is possible to specify by parameter code whether to display in program number order, program name type, or whether to make these displays selectable. Therefore, programs that are managed only by conventional program numbers and have no names can be used as they are, and conventional programs can be used as they are in programs to which the present invention is applied.

In addition, in this example, when registering program numbers and program names in directory files, they are rearranged at the time of registration so that they are always listed in ascending order in each directory file, as shown in Figure 3. Therefore, when displaying, it is only necessary to transfer the files listed in ascending order, and this work can be done instantaneously and the waiting time can be minimized.

In the above description, it has been explained that the program name is mainly given using alphabetical characters, but it is of course possible to use a combination of various words such as αβγ, numbers, etc.

[Effects of the Invention] As described in detail above, in this invention, the program number and program name are written together in the directory for one NG program, and the program can be read from both the program number and the program name. The program is now displayed in ascending order, and management is performed from both the program number and program name.In addition to the conventional program management related to program number display, search, designation, etc., program names with significant properties can also be displayed in ascending order. This makes it possible to smoothly and easily manage a large number of programs, which continue to increase under the trend of FMS.
