Abstract

PURPOSE:To perform the similar plural types of working with use of a single working program and at the same time to perform a series of working with a simple combination of plural programs by registering the executing order of the working program. CONSTITUTION:A setting/displaying device 3 sets the program executing order, the program numbers, and the argument data to a program information memory 8. An executing order controller 7 sends the program numbers and the argument reading commands to a program number reading device 9 and an argument reading device 10 based on the executing order stored in the memory 8. Then the device 9 reads an argument out of the memory 8 with a command of the controller 7 and sets it to a number register 2. In the same way, the device 10 reads an argument out of the memory 8 and sets it to an argument register 11. A program reading device 4 reads a working program out of a program memory 1 based on the data stored in the register 2 and stores it temporarily in a reading buffer 5. Then a program executing device 6 carries out the working program stored in the buffer 5.

Description

DETAILED DESCRIPTION OF THE INVENTION [4i: Field of Application] The present invention relates to a numerical control device that reads and executes a machining program stored in a memory.

[Prior art 1 No. 21 is a diagram showing the configuration of a conventional a-value control device.
In the figure, (1) is a program memory that stores the machining program, (2) is a program number register that stores the number of the program to be executed, and (3) is a setting display device that sets the program number in the program number register (+2). i, +4) is a program reading device that reads a machining program from the program memory of (!) according to the data of the program number register of 12).

(5) is a program buffer that temporarily stores the machining program read by the program succession device (4).

1G) is a program execution device that executes the machining program in the program buffer (5).Next, the operation will be explained. First, the setting display device (3)
The number of the program to be executed is set in the program number register 12). Next, the program reading device (4) reads out the machining program from the program memo (January 1) according to the data in the program number register (2) and stores it in the program buffer (5). and,
Program execution device (6) is program buffer +5)
[Problem to be solved by the invention] Since the conventional numerical control device t is configured as described above, one machining program can only process one fixed item. There was a problem.

This invention was made to solve the above-mentioned problems, and it is possible to process multiple types of similar items with one machining program, and also to create a numerical value that allows a series of machining to be performed by easily combining multiple machining programs. The purpose is to obtain a control device.

[Means to solve the problem]

The numerical control device [4 according to the present invention is capable of registering the numbers of machining programs to be executed in the order of execution.

This allows necessary information to be registered for each machining program.

[Effect]

In this invention, the machining program numbers registered in the order of execution are successively read out in the order of execution, and the nib program with the read number is executed immediately. At the same time, information registered for each machining program is output one after another and passed to the machining program.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
In the figure, (1) is a program memory that stores the machining program, and +81) is the execution order and program number, which are essential information for executing the d (capital) Niprogram.

Program information memo IJ, +31 that stores arguments etc. is (
8) is a setting display device that sets data in the program information memory; 17) is an execution order control device that controls program execution according to the execution order stored in the program information memory (8); +9) is (8) A program number reading device 1121 reads out a program number from the program information memory of (9), a program number register that temporarily stores the program number read by the program number reading device (9). Reference numeral 11 denotes an argument reading device for reading the argument from the program information memory (8), and +111 an argument register for storing the argument read by the argument reading device of Ill at -[times].

Next, the operation will be explained. First, start with the settings display device (3
) to set the program execution order, program number, and argument data used during program execution in the program execution information memo January 8). Next, the execution order control device (7
) refers to the execution order stored in the program information memo (January 8), and the program number,
An argument read command is sent to the program number reading device and the argument reading device, respectively. Next, the program number reading device (9) reads the program number from the program ffff1 memo (January 8) based on the command from the execution order control device (7) and stores it in the program number register 12). Similarly, the argument reading device 11Q is the execution order control device t+
Based on the command 71, the argument is read from the program information memory 18) and set in the argument register aO. Next, the program reading device (4) reads the machining program from the program memory (1) according to the data in the program number register (12) and stores it in the program buffer (5).

The program execution device (6) then executes the machining program stored in the program buffer (5). Also,
At this time, the program execution device (6) uses the argument register fil.
The arguments stored in l are passed to the machining program.

In the above embodiment, arguments are set in the program information memo (January 8), but other information necessary for machining, such as coordinate data of a machining program, may be used. Further, although the program information memo (January 8) shows the amount of - machining, it may be increased by the number of necessary machinings.

〔Effect of the invention〕

As described above, according to the present invention, since the execution order of machining programs can be registered, it is possible to easily combine several programs to perform a series of machining operations.

Necessary information can also be registered for each machining program, which has the effect of increasing the degree of freedom for each of the nine machining programs.
