Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a numerical control device, and more specifically, the present invention relates to a numerical control device, and more specifically, a plurality of programs each having a specific program number,
The present invention relates to a numerical control device that can give a specific program name using predetermined characters and call up the program using the program number or program name.

[Prior Art] FIG. 4 is a block diagram showing a conventional numerical control device.
In Fig. 4, (1) is a machining program file that stores a program created by the user, (2) is a numerical control operation board (hereinafter referred to as the NC operation board), and (3) is
The processing of key switch information from the NC operation board (2) and the operation information in the numerical control device are carried out by the NC operation board (2).
(4) is a machining program processing unit that analyzes the machining program and registers the machining program in the machining program file (1), (5) is a machine control unit that creates machine control commands based on machining data from the machining program processing unit (4) and input information from the machine tool (8), and (6) and (7) are control units for the machine tool (8). The drive amplifier that drives the axis (9) is the numerical control device and the machine tool (8)
It is a mechanical input/output interface that passes signals between the two.

Next, the operation of the conventional numerical control device will be explained. In conventional numerical control devices, settings/
A machining program is input via the display control section (3). The machining program processing unit (4) automatically assigns a number (hereinafter referred to as program number) that identifies the entered machining program, and saves the machining program file (
1) was registered. Therefore, displaying and reading of machining programs are all done using numbers.

That is, when reading and executing a specific machining program from the machining program file (1), the machining program processing section (4) executes the program instructed from the NC operation board (2) via the setting/display control section (3). The machining programs corresponding to the numbers are sequentially read out from the machining program file (1), the machining programs are analyzed block by block, and machining program data is created. When the analyzed block data is transferred to the machine control section (5),
The machine control section (5) sends those data to the drive amplifier (6).
and (7). These signals are amplified by drive amplifiers (6) and (7) to control the machine tool (8).

[Problems to be Solved by the Invention] Incidentally, in the conventional numerical control device having the above configuration, programs are registered and searched by program number. For this reason, it is difficult to tell what kind of program is currently being executed just from the program number.
Even when searching for a registered program, there is a problem in that it is difficult to find the program because the contents of the program cannot be determined from the program number alone.

The present invention has been made to solve the above problems,
The object of the present invention is to provide a numerical control device that allows programs to be registered and searched by any name.

[Means for Solving the Problems] Therefore, the present invention provides a program name input means for inputting a program name, and a registration means for registering the input program name and the program number corresponding to the program name in association with each other. , and search means for searching for a program number corresponding to the program name by inputting the registered program name.

[Function] In the numerical control device having the above configuration, when a program name is input using the program name input means, the registration means registers the manually entered program name and the program number corresponding to the program name, and registers the program name. When a program name is input, the search means searches for a program number corresponding to the program name. Then, a machining program corresponding to the searched program number is called and executed from a machining program file in which a plurality of machining programs are registered.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a numerical control device according to the present invention. Note that in FIG. 1, parts that perform the same functions as those in FIG. 4 are designated by the same reference numerals, and their explanations will be omitted.

In FIG. 1, (1G) is a conversion unit that converts and registers the program name assigned by predetermined characters that can be handled by the NC operation board (2) and the program number handled in the numerical control device; 11) is a memory that stores program names and program numbers.

Next, regarding the operation of the numerical control device according to the present invention, the second
The memory (11) shown in the flowchart in Figure 3 and Figure 3
This will be explained with reference to an explanatory diagram of the stored contents.

(1) Step 91 When a program name, for example "tapping program" is input from the NC operation date (2) via the setting/display control section (3) when creating a machining program, the conversion section (L
O) determines whether the same name as the input program name has already been registered in the memory (11).

(2) Steps 82 to S3 If the manually entered program name is unregistered, a program number corresponding to the program name is automatically assigned, and the program name and program number are associated and stored in the memory (11). (Step S2). Furthermore, the automatically assigned program number is notified to the machining program processing section (4). Inside the numerical control device, the machining program is registered in the machining program file (1) using its program number.

Furthermore, if the input program name has already been registered, this is notified to the setting/display control section (3). The setting/display control unit (3) causes the CRT to display an error message such as "Duwitsumeishoari" (step 83).

In the above manner, the memory (11) is
A program name and a program number corresponding to the program name are registered in , and a program with a program number is registered in machining program file (1).

(3) Step S4 When executing the machining program registered in the machining program file (1), when calling the machining program by program name, set /
When a program name such as "Anaake Program" is entered manually via the display control section (3), the conversion section (l
O) searches the memory (11) and determines whether the program name is registered.

(4) Steps 85 to S6 If a manually entered program name is registered, the program number corresponding to the program name r 000
2J is notified to the machining program processing unit (4) (step S5). The machining program processing unit (4) searches for the machining program file (1) using the number and executes the machining program with program number r0002J. Furthermore, if the input program name has not been registered, this is notified to the setting/display control section (3) (step 5lli). The setting/display control section (3) is configured to, for example,
An error message "Mitouroku" is displayed on the CRT.

In this embodiment, a machining program is searched for and executed by inputting a program name, but a machining program may be searched for by inputting a program number.

According to the present invention, when a program name is inputted, a program number corresponding to the program name is assigned to the program name and registered in the memory, and the registered program name is inputted. Then, the program corresponding to the input program name is searched and executed, so that a numerical control device can be obtained in which the content and type of program can be easily determined.
