Abstract

PURPOSE:To correct message data freely for every system and use by providing a buffer which can correct message data indicating contents of various switches. CONSTITUTION:A working information input medium is read by an input part to control the position of a machine tool through an operating part, a control part 5, etc. This control part 5 is provided with a data setting part 4a of key switches or the like, switch flags 4b, a display part 4d such as a CRT or the like, and a set display part consisting of a message table 4c to perform display of message, etc. In this case, a buffer 8 as a correcting part is added to the set display part to correct message data indicating switch contents displayed on the display part 4d. Then, a message is inputted with keys on the data setting part 4a and is sent to the buffer 8 to generate new message data if said data is corrected. Generated message data is sent to the table 4c to change its contents of message data on the display part 4d.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a numerical control (hereinafter referred to as NC) device configured to be able to modify message data.

[Prior art]

FIG. 1 is a block diagram showing a schematic configuration of a conventional machine tool equipped with an NC device.

In FIG. 1, 1 is a machining information input medium such as a paper tape or data stored in a memory, 2 is an input unit for storing and analyzing machining information from the machining information input medium 1, and 3 is a machine movement and trajectory. A calculation section that performs processing such as analysis and speed control, 4 is a CR and key switches handled by the machine operator.
A setting display section 5 has a T device, etc.; 5 is a control section for transmitting calculation result information from the arithmetic section 3, setting information from the setting display section 4, and machine control commands from K; 6 is a control section for controlling the machine from K; This is a drive unit for driving the machine tool 1 based on information.

Next, the operation will be explained.

The machining information input medium 1 containing machine coordinate values, cutting speed, and other command information is made of, for example, paper tape, etc.
The processing information input medium 1 is read by the input section 2Vc. The setting display section 4 displays message data indicating the contents of the switch as soon as the control section 5 is moved, and sets its valid/invalid state. A precise positional control of the machine tool 1 is achieved via the feed drive part 6.

Conventional NC devices have mostly completely fixed message tables for displaying the valid/invalid state of control switch status signals and for displaying message data indicating the switch contents, so the contents of the message data can be freely displayed. It is impossible to change the system, it is necessary to rebuild the device itself to change the system, and even if the message data is unclear to the machine operator, it is impossible to freely modify it. There was a drawback.

[Summary of the invention]

This invention aims to eliminate the drawbacks of the conventional ones as described above, and by providing a buffer for modifying message data, it has a function that allows message data to be modified freely depending on the system or application. This provides an NC device.

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3.

[Embodiments of the invention]

FIG. 2 is a block diagram of an embodiment of the present invention, in which a buffer 8 as a correction section is added to the setting display section 4.

This buffer 8 is a buffer for modifying message data indicating the contents of the switch currently displayed on the display of the CRT device i or the like.

FIG. 3 is a detailed block diagram of the control section 5, setting display section 4, and buffer 8 which is the correction fl of FIG.

4a is a data setting section such as a key switch; 4b is a switch flag indicating a switch state of the data setting section 4a; 4
d is a display section of a CRT device or the like that displays the valid/invalid state signal of the switch and a message indicating the contents of the switch; 4c is the display section 4; dK is a message 1 message having message data for displaying the message; table,
8 is the kth 1 buffer for modifying the data of the message table 4C.

Next, the operation shown in FIG. 3 will be explained.

Since the data of the message table 4c is displayed on the display section 4d, the switch YON10FFL and its status signal are received and held by the switch flag 4b by operation from the data setting section 4a.

The switch flag 4b is sent to the control section 5 as control information, and to the display section 4d as display information indicating whether the switch is enabled or disabled, which is the same as in the prior art.

Here, if the message data displayed on the display section 4dK is inappropriate, the operator should select the message data displayed on the display section 4dVc.
Set the number of the corresponding data.

Next, when a character code indicating a message is input using the keys of the data setting section 4a, it is sent to the pants 78, which is a correction section, and new message data is created. By sending this message data to a designated position n in the message table 4C and displaying it, the message data on the display section 4d can be changed to appropriate data.

In the above embodiment, the case where the display message of the control condition in the NC device is corrected by inputting change data from the key was explained, but it is also possible to obtain the input data from paper tape etc. by providing a tape reader. Yes, it has the same effects as the above embodiment. Furthermore, N
When checking the validity of each switch at the time of connection with the NC device in a machine tool using C device, if you create a sheet of paper to display the contents of the necessary switches in advance, you can send messages one after another. You can rewrite the contents of line 5, making it easier to check and ensure that line 5
I will be able to do it.

〔Effect of the invention〕

As mentioned above, this invention provides various switches for the machine, the sequence of the machine, and other controls,
In the NC device, the NC device has a setting display unit that includes a display unit that displays valid/invalid status signals of the switch and a display unit that displays message data indicating the contents of the switch, and the message data can be corrected by indicating the contents of the switch. Since it is equipped with a built-in buffer, if the switch contents change due to changes in the system, it can be handled by setting and displaying the message data on the CRT, which eliminates the need for product modification and the waiting time required for the change. It is reasonable because it is unnecessary, and -! This has the effect of facilitating operation because the machine operator can modify the message data by himself.
