Abstract

PURPOSE:To eliminate a need for a processing to select processing contents at the time of execution by causing a system program to be a module, storing the program to a ROM, selecting this program, linking it and loading it to a RAM as an executable program. CONSTITUTION:A system program 2 is caused to be the module per processing content and the modules such as processing A, processing B,... processing I, etc., are stored in a ROM 1. When a powder source is inputted, a module program necessary for each machine tool is selected out of the respective module program of the system program 2 in the ROM 1 and these programs are linked. Then, an executable system program is prepared and loaded to a RAM 3. Which program module is selected is set by a parameter with being matched to the specification of each machine tool and by this parameter, the necessary processing program is selected.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a loading method for a numerical control device in which a system program is loaded from a non-volatile memory to a RAM to operate the numerical control device, and in particular, it relates to a loading method for a numerical control device in which a system program is loaded from a non-volatile memory to a RAM to operate the numerical control device. , relates to a loading method for a numerical control device in which a necessary module program is selected and loaded.

[Conventional technology]

In the numerical control device (CNC), the system program is RO
There are systems that are stored in a non-volatile memory such as M and then read out and executed, and systems that are stored in a ROM and then loaded into a RAM and executed. The reason for partially loading data into RAM is that RAM generally has a faster read speed than ROM and can be rewritten.

FIG. 4 shows an example of loading a system program. In the figure, 1 is a ROM in which a system program 2a is stored. This system program is configured as a single system program. 3 is a RAM, and the system program 2a is loaded into the RAM 3 as a system program 4a that can be executed as is.

On the other hand, a numerical control device is connected to various types of machine tools to form a numerically controlled machine tool, but since each machine tool has different specifications, a system program tailored to the specifications of the machine tool is required. That is, the system program 4a includes processing contents necessary for a wide variety of machine tools, and the system program is executed while selecting the processing necessary for each machine tool.

FIG. 5 shows a flowchart of processing of such a system program. In the figure, the number following S indicates the step number.

(Sll) Check whether to perform process A. If the process A is necessary, the process goes to S12, and if it is not necessary, the process goes to S13.

(S12) Process A is executed.

(S13) Check whether processing B is necessary. If process B is necessary, the process goes to S14; if it is not necessary, the process goes to the next step.

[S14] Process B is executed.

In this way, the system program 4a is executed while checking whether each process is necessary.

[Problem to be solved by the invention]

However, for this reason, each processing of the system program
Determining whether processing is necessary wastes system program execution time. In particular, as the functions required of a numerical control device become more complex and diverse, the number of determination steps also increases.

The present invention has been made in view of these points, and an object of the present invention is to provide a loading method for a numerical control device in which a system program is modularized, and necessary modules are selected and loaded. .

[Means to solve the problem]

In order to solve the above problems, the present invention uses a loading method for a numerical control device in which the system program is loaded from a nonvolatile memory to a RAM to operate the numerical control device, and the system program is created as a module program for each processing content. , Select a module program necessary for each numerical control device system from the module programs, create an executable system program, load the executable system program into RAM, and operate the numerical control device. A loading method for a numerical control device is provided.

[Effect]

The system program is configured as a module program for each process, and only the module programs necessary for each machine tool are selected and linked to create an executable system program and loaded into RAM. There is no need to judge whether processing is necessary when executing.

〔Example〕

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

FIG. 1 shows a conceptual diagram for explaining the loading method of the numerical control device of the present invention. In the figure, 1 is a ROM,
System program 2 is stored. This system program 2 is modularized for each processing content, and is composed of modules such as processing A, processing B, and processing I.

3 is a RAM, when the power is turned on, a module program required for each machine tool is selected from each module program of the system program 2 of ROMI, and these are linked to create an executable system program. Load into. Which program module to select is set by parameters according to the specifications of each machine tool, and the necessary processing program is selected by these parameters.

Therefore, the system program 4 including process A, process C1 process D, process G and process 1 necessary for a specific machine tool is R
Loaded into AM3. As a result, the numerical control device only needs to execute the system program 4 including the necessary processing,
It does not include unnecessary processing.

FIG. 2 shows a flowchart of the processing of the system program. As shown in FIG. 2, the execution of this system program does not require any judgment processing to select the necessary processing, and the process A (SL), Process C (32), etc.
, Process D (S3), Process G (S4) and Process I (S5
).
