Abstract

PURPOSE:To obtain a numerical controller, to which users can give G-commands while making conversations with the CRT without referring to an instruction book, by providing an explaining graphic displaying circuit which displays explaining graphics for illustrating formats corresponding to each G-command when a G-command is inputted. CONSTITUTION:When a work program is inputted through keys from an operation panel 3, a G-command is received by the G-command checking circuit 21 of an explaining graphic displaying circuit 20 and the received G-command is compared with a G-command table 22. When the G-command is an usable one, a standard graphic corresponding to the inputted G-command is referred to a standard graphic drawing table 24 at the next display circuit 16 and the standard graphic is displayed on a CRT17. That is, an explaining standard graphic is displayed in a standard graphic displaying area 18 at the right end of an editing screen when keys N, 3, G, and 1 are depressed in the order and the screen operates to explain X, A, R, etc., to be inputted next. When the G-command is unusable one, an error message is displayed on the CRT17 by an error processing circuit 23.

Description

[Detailed description of the invention] [Technical field of invention].

The present invention relates to a numerical control device (hereinafter referred to as an NC device 2) that enables a user to manually input a program for a numerical control device using keys from an operation panel, and to do so more smoothly and efficiently.

[Prior art].

FIG. 1 is a block diagram showing the configuration of a conventional NC device of this kind, in which numeral 1 indicates a 7-pipe containing a program written in the NC language, and numeral 2 indicates a reading circuit 1 for reading the tape 1.
．． 3 is an operation panel, 4 is a buffer 7 memory, 5 is an instruction decoding processing circuit, 6 is a pre-calculation circuit, 1 is a control circuit, 8 is an axis movement amount output circuit, 9 is a pulse distribution circuit, 10 is a servo unit, 11 is a motor, 12 is a detector, 13 is a spindle rotation detector, 14 is a programmer controller (hereinafter referred to as PC), 15 is a machine tool to be controlled, 16 is a display circuit, and 17 is a CRT.

Next, the operation will be explained.

The program contents of the tape 1 are read by the reading circuit 2, temporarily stored in the buffer memory 4, and preprocessed by necessary numerical calculations by the instruction decoding processing circuit 52 and pre-calculation circuit 6, and the resulting data is used for the next control. Sent to circuit 1,
Online control takes place. In other words, 1 of the program
The axis movement amount of the machine tool 15 is applied to the axis movement amount output circuit 8, the pulse distribution circuit 9 is also caused to output pulses, the servo unit 10 is operated, the motor 11 is driven, and the axis is moved. A detector 12 is attached to the motor 11 to detect the amount of displacement of the motor 11 and feed it back to the servo unit 10 to drive the motor 11 by a predetermined amount. The spindle rotation detector 13 is attached to the spindle for the purpose of detecting the rotation speed of a rotating workpiece or rotating tool, and feeds back the rotation speed of the spindle to the pulse distribution circuit 9 to determine the rotation speed of the motor 11. Synchronize with the spindle rotation speed. In addition, PCl4 controls other than the shaft drive of the machine tool 15,
An example is a sequencer that controls hydraulic pressure and the like.

Further, the display circuit 16 creates a screen image corresponding to each screen and displays it on the screen of the CRT 17.

On the other hand, if you want to register a new member's list of members of the Canadian program, select the editing screen shown in FIG. That is, in the case of FIG. 2, N, 3. G.1. X,
2,0. ...That's how it goes.

In this way, the operation panel 3 and CRT 17 can be
When manually inputting a program using ', nothing other than the program that the user manually input was displayed on the editing screen, and the user had to memorize all the formats corresponding to each G command.

However, in reality, this is impossible, and input must be made while looking at the manual, which requires unnecessary human effort and leads to a deterioration in the operating efficiency of the NC device.

[Summary of the invention]

This invention has been made to eliminate the drawbacks of the conventional ones as described above, and by providing an explanatory graphic display circuit that displays an explanatory diagram illustrating the format corresponding to each G command button when a G command is input. , provides a numerical control device that allows a user to give a G command while interacting with a CRT without looking at a manual.

[Embodiments of the invention]

Examples of the present invention will be described below.

FIG. 3 is a schematic diagram of the main parts of an embodiment of the present invention, in which an explanatory graphic display circuit 20 is inserted between the operation panel 3 and the display circuit 16 in FIG. G
The command check circuit 22 is a G command table in which the numbers of usable G commands are stored in advance. 2i is an error processing circuit, 24 is a standard figure drawing table, and G
A standard figure for explaining the command format is stored in advance for each G command. FIG. 4 shows the case of the G command (()01), which is an example of this standard figure.

In other words, the data following the GO1 command is X, U.

There are Z, W, A, D, R, etc., and the actual dimensions and angles of these are explained.

Next, we will explain the operation of the embodiment shown in FIG.
If the G command is usable, the next display circuit 16 displays a standard graphic corresponding to the number of the input G command. That is, when you press N, 3, 0.1, and 1000 on the editing screen shown in Figure 2, the standard explanatory figure shown in Figure 4 appears on the screen as shown in Figure 5. It is displayed in the standard graphic display area 18 at the right end, and operates to explain the next input, such as X, A, and R. Also,
If it is an unusable G command, the error processing circuit 23 will
Display error message on CRT17.

〔Effect of the invention〕

As explained above, this invention includes a G command table that stores usable G commands, and a standard drawing table that sends out standard figures corresponding to G commands entered manually on the 081 screen. Since a graphic display circuit is provided, when the user manually presses the keys from the program operation panel, the user can
Since you can press the G command manually without interacting with the screen, there is no need to refer to the manual. Therefore, the key manpower time is significantly shortened, which has the advantage of improving the operating efficiency of the NC device.
