Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention associates tool information data and macro variable information data necessary for executing an NC machining program with an NC machining program for each type of workpiece. The present invention relates to a numerical control device that enables the numerical control device itself to perform system management by storing information in each memory.

[Conventional technology]

Recently, numerical m (NC) equipment has been
The processor is configured to incorporate a computer called a uterized NC, and the processor causes the NC machine tool to execute predetermined operations instructed by the NC machining program based on the control of the system control program, thereby machining the desired parts.

The NC machining program in such an NC device is generally composed of multiple NC machining programs such as a main program, subprograms, and custom macro programs for machining a specific type of workpiece. It is true. In addition, in order to operate the NC machine tool with the commands of these multiple NG machining programs, data in the tool information memory (tool offset amount, tool life, spare tool file data) and data in the macro variable information memory (macro variables ) is also required. The main program is programmed with movement commands, feed rate commands, spindle rotational speed commands, auxiliary function commands, subprogram call commands, macro program call commands, tool exchange commands, and the like.

The subprogram call command calls the subprogram with the program number specified by the command, and the macro program call command calls the custom macro program with the program number specified by the command.

In this custom macro program, instead of giving numerical data directly to a certain address, it is programmed in the format of a macro variable, and when this block is executed, the macro variable with the number specified by the program in the macro variable information memory It is possible to read the data at that address, stop the data at that address, and execute it.

Further, if a tool length (diameter) correction command is included in the main program or subprogram, the tool length (diameter) correction is executed according to the data of the correction number specified by the command in the tool information memory.

When operating a conventional NC machine tool as a system, the NC device is connected to the host computer, and each time the type of workpiece changes based on the machining schedule, the host computer sends an NC message to the NC device. The machining program and tool information data were loaded, and NC machining was performed.

You can also connect an external storage device to the NC device and
, processing information of the workpiece identified by the NC device (
There is also a method of transmitting NC machining programs, tool information data) from an external storage device to an NC device to perform NC machining.

[Problems to be solved by the present invention]

Incidentally, recent NC devices are becoming more sophisticated and their memory capacity tends to increase, and it is desired to realize an NC device having a configuration in which the NC device itself can perform system management.

However, conventional NC devices were unable to store and manage tool information data in the internal memory in correspondence with the NC machining program for the workpiece.In addition, macro variable information data was not attached to the NC device. The only way to change the value was to rewrite the value in the macro variable information memory using an input method (keyboard, etc.).

In this way, the NC device itself cannot store and manage the tool information data and macro variable information data necessary for NC machining in accordance with the NC machining program, so the NC device itself cannot perform system management. There was a problem.

The present invention has been made to solve the above problems, and the NC device itself stores the NC machining program in the internal memory.
System management is also performed by managing the machining information necessary for NC machining according to the type of workpiece that has been identified by making it possible to store and manage tool information data and macro variable information data in association. The purpose of the present invention is to provide an NC device that can perform the following functions.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a block diagram of an NC device implementing the present invention, and FIG.
The figure is an explanatory diagram of the data storage state of the NC program memory and the macro variable information memory, and FIG. 3 is an explanatory diagram of the implementation of the present invention.

In FIG. 1, 1 is an NC device, and this NC device l
has a processor (CPU) 11 and a pass line 20
is connected. This pass line 20 includes a RAM 12 for storing processing results, etc., a ROM 13 for storing a system control program for the NC device 1, an NC program memory 19 for storing an NC processing program for machining, etc., and for displaying various data. A display device (CRT) 18a, which is a display means, and a keyboard 18b, which is an input means for inputting various commands, are connected.

A tool information memory 1 stores tool information data related to the tool (tool offset amount, tool life, spare tool table, etc.) as numerical data in a first storage format.
4 and a macro variable information memory 15 that stores macro variable information data regarding macro variables of the custom macro program in the first storage format are connected to the path line 20.

Similarly, tool information memory 14, macro variable information memory 1

+...) into a second storage format in which the data is stored as the same character data, or a storage format conversion means 16 that converts data stored in the second storage format into the first storage format; The data converted into this storage format is stored in the NC program memory 19 in correspondence with the type of workpiece, etc.
Or tool information memory 14, macro variable information memory 1
A storage management means 17 for managing the storage in the path line 20 is also connected to the path line 20.

In the tool information memory 14 and the macro variable information memory 15,
The data specified by the type of workpiece, etc. is a number in the memory (for example, see #i, #2, #3, etc. in Figure 2).
Each is stored in the first storage format, which is the long word long real number type according to the IEEE (Institute of Electrical and Electronics Engineers) standard. Then, when the NC machining program or custom macro program is executed, the data of the specified memory number (a″ b in FIG. 2).

c l , . . .) are read from each memory and executed.

Further, the NC program memory 19 contains N for work A.
C machining program Pal+NC machining program Pbl for workpiece B is stored. Similarly, macro variable information data (see allblo, C'', etc. in Fig. 2) and tool information data specified by the type of workpiece, such as workpiece A and workpiece B, are stored in the first storage. Depending on the format, the data is converted into a second storage format in which it is stored as character data, that is, a storage format in ASCII code, and is stored by the storage management means 17 in association with the NC machining program for machining this workpiece.

The storage type conversion means 16 mutually converts between the first storage type and the second storage type. The storage format conversion by this storage format conversion means 16 is as follows:
This is done as follows.

Since macro variable information data and tool information data are converted using the same method, explanation will be given using macro variable information data as an example.

The macro variable information data is stored in the macro variable information memory 15 as a long word length real number type according to the IEEE standard.For example, the numerical value 14.2857 is 0X35.0Xef.
, ()X3B, 0X45 , 0X47 , 0X9
2.0X2c, stored as 0X40. In order to convert this into the second storage format, the data is read nibble by nibble from the macro variable information memory 15 and converted into ASCII code. That is, the above data is 0X330X350X450X460X330X38
0X340X350X340X370X390X320
It is converted to X320X430X340X30.

In this way, the storage format is converted and the data is transferred from the macro variable information memory 15 to the NC program memory 19. Furthermore, when transferring the data in the NC program memory 19 to the macro variable information memory 15, this procedure may be performed in reverse.

In this way, the NC program memory 19 contains, for example,
The NC machining program Pa++ for workpiece A, the macro variable information data Pag for workpiece A, and the tool information data Pa3 for workpiece A are associated as one set, and are based on the program number of the same NC machining program (or main program). They are stored and managed using the same storage format. Similarly, NC machining program Pb for workpiece B, workpiece B
Macro variable information data pb for work B, tool information data Pb for work B.

are stored and managed in association with each other (see Figures 1 and 3).

Next, the operation of the present invention will be explained in detail.

When the processor 11 of the NC device 1 specifies that the workpiece to be machined next is the workpiece A, the processor 11 of the NC device 1 stores the NC program memory 19.
A command is output to transfer the macro variable information data P a z + tool information data Pa= in each memory.

In other words, the data (a, bIF, cIf, etc.) that are arranged in series in the order of numbers in memory using ASCII code are sequentially converted into the long word long real number type of the IEEE standard, and for each number in memory, the data is The storage type conversion means 16 and storage management means 17 are operated to store data (a f , b ICo...) in the memory area of the internal memory number. Then, the NC machining program Pa is read one block at a time and NC machining is performed.

In addition, when machining workpiece A is finished and the next workpiece, for example workpiece B, is to be machined, the data for workpiece A in the macro variable information memory 15 and tool information memory 14 conforms to the I EEEE standard. It is transferred and stored in the NC program memory 19 in association with the NC machining program Pa converted from the long word length real number type to ASCII code.

As a result, even if the data in each memory is rewritten during NC machining, the latest data is always stored and managed in association with the NC machining program.

As shown in FIG. 3, when the processor 11 identifies the aim of the workpiece, the processing information (
NC machining program, macro variable information data, tool information data) is selected, and the macro variable information data and tool information data associated with the NC machining program are transferred to the macro variable information memory 15 and the tool information memory 14. Since NC machining is performed, system management can be performed by the NC device itself.

As described above, in the present invention, processing information necessary for NC processing of the workpiece can be transferred to the memory in the NC device without separately providing hardware such as an external storage device or an interface.
Since the information can be managed and stored in association with the machining program, the NC device itself can perform system management.

〔Effect of the invention〕

As described above, according to the present invention, various machining information (NC machining program, macro variable information data, tool information data) specified for each type of workpiece can be stored and managed in association with the internal memory of the NC device. , system management can be performed by the NC device itself. Furthermore, since system management can be performed without separately providing hardware such as an external storage device or an interface, the economical effects are also significant.
