JPS63271608A - File control system for nc program with transfer history information - Google Patents

Abstract

PURPOSE:To facilitate the confirmation of a transfer history by adding transfer history information to control information and displaying it on a display means every time an N program is transferred in a data processing procedure. CONSTITUTION:This system is provided with an automatic programming device 1, an DNC controller 4 to which a floppy disk 2 and a tape reader 3 are connected, an NC device 6, and an NC working machine 7. A version number '1' is registered as the control information in a file of an NC program PA, PB, or PC and a version number which is registered as the control information in the file of an NC program PD outputted from the NC device 6 is stored on the disk 2, etc. Then every time an NC program is transferred among various devices, different transfer history information is added as the control information to the file of the NC program. Here, the control information is displayed to confirm the transfer history of the NC program.

Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a case where transfer history information is registered and managed as management information in an NC program file for controlling a numerically controlled (hereinafter referred to as NG) processing machine. This invention relates to a file management method for an NC program.

(Technical background and problems to be solved) NC programs stored in the memory of NC devices and DNC (Direct NC) controllers (devices that connect and collectively control multiple NC processing machines) include It can be divided into those with a proven track record and those with no processing track record. This NC program with a proven track record is one that has been
An NC program that has been executed on a processing machine and whose operation has been confirmed and has no machining experience is one that requires a test to confirm its operation.

In the conventional NC program file management system, there is no way to distinguish whether or not there is a machining record as described above, so before an operator etc. performs machining, it is necessary to check whether the program being used has a machining record or not, that is, the transfer history. The disadvantage was that it required checking. As a result, there is a problem in that the operating rate of the NC processing machine decreases.

(Object of the Invention) The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide an NC program having transfer history information that allows the transfer history of an NC program to be easily checked.
Its purpose is to provide a file management method for the program.

(Means for Solving the Problems) The present invention relates to a method of registering management information in a file of an NC program for controlling a numerically controlled processing machine, and managing the NC program with the file. The above object of the present invention is to add transfer history information to the management information each time the NC program transfers data between data processing means, and to display this added management information on a display means. achieved.

(Operation of the Invention) The present invention adds different Ih transmission history information to the NC program file as management information each time the NC program is transferred between various data processing devices, displays the management information, I decided to check the transfer history.

(Embodiment of the Invention) Information such as the file name and the data capacity of the file can be registered as management information in the file of the NC program that is input to the NG device or the DNC control tape. In the method of the present invention, it is further possible to register a version number that allows the transfer history of the NC program to be registered in the management information, and when an operator etc. indexes the file name of the NC program, the registered information is displayed on the display devices of the NG device and the DNC controller.

FIG. 1 is a block diagram showing an embodiment of a device for realizing the NC program file management method according to the present invention, in which an NG program PA output from an automatic programming device 1, a floppy disk 2 or a tape reader 3,
When the version number "i" is registered as management information in the P[l or PC file, and the version number registered as management information in the NC program PD file output from the NC device 6 is 4".

, the version number °゛2°゛ is registered as management information in the PF or PC file, and the NG program pH output to the NC processing machine 7 is managed in the NG program PI file when executed on the NC processing machine 7. The version number "3" is registered as information, and when outputting the NC program PI of the execution method to the DNG controller 4, the version number "3" registered as management information in that file is changed to "4". An NC device 6 is provided for storing the NC programs PM3, PM4 on the floppy disk 2 or the tape puncher 5, which have undergone registration changes and undergone the above-described processing.

Next, the operation of the DNC controller 4 will be explained using the flowchart shown in FIG.

In the above explanation, the version number is set to °°1'' for the NC program file manually input to the DNC controller from an external manual means, and the version number is set to 2° for the NC program file transferred from the DNC controller to the NC device. In addition, set the version number to 3' for the NC program file executed on the NG processing machine, and set the version number to '4' when the executed NC program was transferred from the NC device to the DNG controller. ing.

FIG. 4 is a diagram showing an example of indexing and displaying the file name of an NC program that has been subjected to the processing described above on a display device.
The transfer history of the C program can be determined based on version A.

Note that the above-mentioned version number is not particularly limited, and may be any other number or symbol that can be distinguished. Also, when updating the version number, consider the version number currently registered on the side sending the NC program.1.
You can also change the version number using a keyboard or the like.

(Effects of the Invention) As described above, according to the method of the present invention, the transfer history of the NC program can be easily determined by managing the version number, so it is possible to significantly reduce the number of man-hours, and It becomes possible to improve the operating rate of the NG processing machine.
