JPS62293310A - Executing system for user program of numerical controller - Google Patents

Abstract

PURPOSE:To improve the actual working efficiency of a user program by forming a processing system so that a background user program is executed regardless of the start state of a numerical controller NC and therefore executing the user program even in a non-NC start mode. CONSTITUTION:A foreground user program is read within a memory as long as a start state is decided the NC start state deciding process. Then the read program is analyzed and executed. While a background user program is read regardless of the presence or absence of the NC start state and analyzed and executed. In this case, a program produced previously by a user functions as a translation system program for the program to be executed. Furthermore, it is possible to always give the higher priority to the foreground user program for execution.

Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] This invention relates to a user program execution method for a numerical control device (hereinafter referred to as NC) that includes an editing program and an interpretation program. be.

[Conventional technology]

Conventionally, in NC, the user program is EIA
(HIec, tronic Industries
This refers to two types of programs: a machining program in the AS5ociation) format, and a user macro program that extends the machining program to make it possible to use commands prepared in the BASIC language. Each program is analyzed and executed by an interpreter, which is a program that interprets and executes the source language commands one by one when the machine is started.

The figure is a configuration diagram of the NC device hardware.

Next, the operation will be explained with reference to FIGS. 2 and 3.

First, the NC is in the activated state at A, that is, when the NC operator presses the crab start button, the NC executes the manual analysis process (2-1) of the machining program, and based on the processing result, the machining program performs the user macro process. (2-2), it is determined whether there is distortion. If YES, the user macro process (2-3) is executed, followed by calculation of the motor movement amount (2-4) by the main CPU. Furthermore, the main CPU performs the calculation of the incremental movement amount (ΔX, ΔY) of the NC, correction calculation, etc., as well as interpolation processing (1-5) for straight lines, circular arcs, etc. Control is performed to proceed with processing. Finally, the end of the machining program is confirmed (2-6), and the series of processing is completed. The processing program and workpiece machining program for operating the NC device are stored in advance in non-volatile memory (RO
M or bubble memory, etc.).

[Problem that the invention seeks to solve]

Since the conventional NC is configured as described above, the user program is read, analyzed, and executed only when the NC is activated, so the user program cannot be executed when the NC is not activated. There was a problem in that the actual efficiency of NC operation was restricted.

The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a user program execution method for a numerical control device that allows the user program to be read, analyzed, and executed even when the NC is not activated. purpose.

[Failure to solve the problem]

The NC user program execution method according to this invention is
This allows a user program to be executed as a background user program even when C is not activated.

[Effect]

The NC user program according to the present invention is divided into a foreground user program and a background user program and stored separately.
Even when the NC is not activated.

Enables the execution of user programs in the tagground user program. Here, foreground processing means high priority processing that precedes interrupt result bank ground processing. Generally, jobs that are processed in the foreground require relatively fast processing or are commonly required, and therefore have a memory area for foreground processing in the memory. In addition, jobs that require many resources and a large amount of processing, and are not very urgent, are processed in the background.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In the figure, the same parts as in Figure 2 are designated by the same reference numerals.
In the figure, (C) is the foreground, loading the user program (2-7) is the bank background, loading the user program (2-8) is the loaded background, and analyzing and executing the user program. In addition, <1-1) is the keyboard (1-2) used by the operator to input data, and the editing program (1-3) is the memory that stores the user macro program, which is used to interpret hackground data created by the user in advance. Analyze and execute the programmed form.

Next, the operation will be explained. First, as a result of performing the NC activation state determination process (^), if it is activated, the foreground user program (C) is read, and the read program is analyzed and executed (2-1, 2-4, 2-5
>. On the other hand, the process of reading the background user program (1-7) is performed regardless of whether the NC is activated, and the analysis and execution of the loaded background (
2-8) is performed. The program executed at this time is a block 1': I-gram created in advance by the user, which functions as an interpretation program.

Note that in the above embodiment, when the NC is activated, the background user program is always executed after the foreground user program is executed. It is also possible to always perform preferential processing for processing one knee block gram. In this case, the background user program is always processed during the idle time of the foreground user program.

〔Effect of the invention〕

As described above, according to the present invention, since the processing method is formed so that the background user program is executed regardless of the NC activation state, the user program can be executed even when the NC is not activated, and any arbitrary This has the effect that the user can easily add functions to the program, and the actual efficiency of the NC device can be greatly improved.
