DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for managing a machining program of a numerical controller, and more particularly to a method and an apparatus for managing an O number of a program memory.

[0002]

2. Description of the Related Art In a numerical control device, a machining program is managed by a program name composed of O and a numerical value called an O (O) number, and a machining program is designated from an operation panel and other machining from a machining program. The call of the program uses the O number. On the other hand, as a holding type memory for storing a machining program in the numerical controller,
Conventionally, a CMOS memory has been used, but a flash memory, a hard disk, or the like has come to be mounted as a large-capacity memory cheaper than the CMOS memory. However, when memories of different media are mounted in the numerical controller and used as machining program memory, the memory access performance and access specifications are different, so these multiple memories are used as one continuous machining program memory. Can not. For this reason, in the conventional technology,
The processing program was separately managed for each memory of different media.

[0003]

In the case of such a management method, since the same O number may exist in memories having different media, a machining program cannot be uniquely specified only by the O number. For this reason, when calling a machining program stored in the memory of the medium B as a subprogram from a machining program stored in the memory of the medium A, a special call command indicating that the memory is the memory of the medium B is required. When a processing program is input from an operation panel or an external device or output to a display or an external device, a processing program creation or a processing program is performed, such as a different operation for the memory of the medium A and an operation for the memory of the medium B There was a problem that the input / output operation of the computer became complicated. SUMMARY OF THE INVENTION It is an object of the present invention to eliminate limitations due to a plurality of machining program memories in machining program creation and machining program input / output operations.

[0004]

In order to solve the above-mentioned problems, the present invention provides a numerical controller having a plurality of program memories by assigning a different O number range to each of the program memories. Is a method for managing a machining program in a numerical control device characterized in that a plurality of program memories are managed by a single program management unit. Display / input / output control unit that performs

The data holding memory 5 stores an O number to be processed by the numerical controller and a boundary value of a range of the O number stored in the hard disk memory 7. The CMOS memory 6 and the hard disk memory 7 store processing programs. The processing program management unit 4 is a processing block that writes and reads a processing program to and from the CMOS memory 6 and the hard disk memory 7. The machining program analysis unit 8 is a processing block that receives program data from the machining program management unit 4, analyzes the program data, and passes the analysis result to the pulse distribution unit 9. When the result of the analysis indicates that another processing program needs to be analyzed, the processing program management unit 4 also requests the processing program for the processing program. The pulse distributing unit 9 controls the servo drive unit 10 based on the analysis result.
Command to Next, O managed by the numerical controller
A description will be given of an embodiment in which a machining program having a five-digit number and an O number of O10000 or more is stored in the hard disk memory 7. First, the setting of the assignment of the O number to the CMOS memory 6 and the hard disk memory 7 will be described. An operator inputs a boundary value of the O number range stored in the hard disk 7 on the operation panel 1. From the operation panel 1,
When 10,000 and 99999 are input, the display / input / output control unit 3 stores 10,000 and 999 in the data holding memory 5.
A value of 99 is written, and this value is stored in the data holding memory 5. Next, processing when a machining program is newly created will be described. When the operator inputs an O number of a newly created machining program on the operation panel 1, the machining program management unit 4 stores the numerical data of the inputted O number in the O number range boundary value stored in the holding memory 5. Compare with If the number is 10,000 or more and 99999 or less, the write target is the hard disk memory 7; otherwise, the CMOS memory 6 is used. When an operator inputs a machining program command on the operation panel 1, writing is performed on a memory to be written. In this way, O

The processing program of 999 is stored in the CMOS memory 6, and the processing programs of O1000 to O99999 are stored in the hard disk memory 7. Subsequently, a case where machining is performed according to a machining program will be described. The operator inputs an O number to be processed on the operation panel 1. When an O number to be processed is input from the operation panel 1, the display / input / output control unit 3 writes the value of the O number to be processed into the data holding memory 5 and stores the value in the value data holding memory 5. Is done. Next, the operator inputs a processing start signal on the operation panel 1. display/
The input / output control unit 3 reads the machining target O number stored in the data holding memory 5 and
Notify. The machining program management unit 4 compares the numerical value of the O number with the boundary value of the O number range stored in the data holding memory 5 in the same manner as in the case of writing. 100
If it is not less than 00 and not more than 99999, the read target is the hard disk memory 7; otherwise, it is the CMOS memory 6. The read program data is transferred to the program analysis unit 8. The machining program analysis unit 8 analyzes the received program data and transfers the result to the pulse distribution unit 9. When a subprogram call command is detected as a result of the analysis, a subprogram is requested to the machining program management unit 4. The machining program management unit 4

[0006]

As described above, according to the present invention, since the O numbers stored for each machining program memory are different, the O numbers do not overlap between different machining program memories. For this reason, a desired machining program can be designated only by designating the O number without being aware of the storage location of the machining program in the machining program creation and machining program input / output operations.
