Abstract

PURPOSE:To display various pieces of information from a machine tool on the CRT display device provided at a numerical controller side by providing an MDI key image register, CRT image register, etc. CONSTITUTION:When an interface processor 7 decides that a key for reading the contents of an MID key image register 12 for manual data input devices, state information is read through a data input device 11 and stored in a magnetic bubble memory 10. When this processing is completed, the state information is set in a CRT image register 13. An NC processor 3 reads the contents of the register 13 in interface in-use mode and outputs them to the CRT display device 6 to display information conforming to the contents of the register 13. Namely, the MDI key image register, CRT image register, etc., are provided to display various pieces of information from the machine tool on the CRT6 provided at the numerical controller side.

Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to an interface section of a numerical control device, and in particular, a method for transmitting various information on a machine tool side by operating a manual data input device (MDI) provided on the numerical control device side. Similarly, MDI can be displayed on a CRT display provided on the numerical control device side.

This invention relates to a CRT interface device.

Prior Art and Problems In numerically controlled machine tools, there is a method for notifying the operator of various machine tool conditions, such as running out of oil.
It is conceivable to light up a lamp or the like provided on the machine tool side, but this would require a dedicated display device, which would increase costs.

In particular, as the amount of information increases, a simple display cannot handle it, and a large display is required, which becomes increasingly uneconomical.

Purpose of the Invention The present invention improves these conventional drawbacks, and
The purpose is to display various information from the machine tool on the CRT display C2 provided in the numerical control device.

Embodiment of the Invention FIG. 1 is a main block diagram showing an example of the hardware configuration of a numerical control device having an MDI and CRT interface device according to the invention. In the figure, 1 is a ROM that stores system programs, etc., 2 is a RAM that stores computer programs, etc., 3 is a system program stored in ROM 1, which defines the overall operation, and RAM 2
It decodes and executes the machine program stored in the servo motor 4 to perform numerical control of a machine tool (not shown), and also reads key information from the MDI 5 and reads the key information from the CRT H.
This is an NC processor that controls the display of the indicator 6. Further, 7 is a processor for interface with the machine tool, and via a path 8, a ROM 9 for storing control programs, etc., a writable/readable memory such as a magnetic bubble memory 10, a data input device 11, an MDI key image register. 12, connected to each peripheral circuit of the CRT image register 13. MDI key image register 12,
CRT image register 16 is also connected to NC processor 3 via path 14 . The right side of the dashed-dotted line 15 in the figure is the NC side, and the left side is the interface side.

The MDI key image register 12 is a register for passing the key image of 1MDI5 to the interface side, C
The RT image register 16 is a register for passing a CRT image created on the interface side to the NC side, and both registers can be read and written from either the NC processor 5 or the interface processor 7. Further, the data input device 11 receives various information M1 to M3 from a machine tool (not shown).

2 and 6 are solo charts showing an example of processing performed by the NC processor 3, and FIG. 4 is a flowchart showing an example of processing performed by the interface processor f7. '11,,S'
20 to S22 indicate each step.

The NC processor 6 controls each key of the MDI 5.

After reading the off state, it is determined whether the key operation matches a predetermined interface use command (S1, S2). This is for example MD
An interface use command key is provided in I5, and it can be determined whether or not this key is pressed. Next, press the MD command key followed by the interface use command key.
It reads the key information of I5, writes the information to the MDI key image register 12 (S3), and shifts to the interface use mode.

The interface processor 7 grasps the contents of the MDI key image register 12 by reading the contents at regular intervals, for example (S20).

When determining that a certain key has been pressed, the process corresponding to that key is executed. For example, if the diagnosis key DGNO8 in the MDIB is previously assigned to the machine tool status display key, when this key is pressed, the interface processor f7 receives various information from the machine tool via the data input device 11. Processing is performed to read the status information from inside and store it in the magnetic bubble memory 10. When this process is completed, status information is set in the CRT image register 16 (822).

In the interface use mode, the NC processor 3 reads the contents of the CRT image register 13 (, s'io) and transfers it to the CRT
Display unit 6 (CRT image register 1 by outputting two
The information that matches the content ζ2 of item 3 is displayed (S11).

Therefore, in the above example, the state of the machine tool is displayed on the CRT screen. Furthermore, in display control other than the interface use mode, the NC processor 3 does not display the contents of the CRT image register 16;
When the diagnosis key DGNO8 in DIS is pressed, a known self-diagnosis function is executed to display the status of the numerical control device. That is, when the interface use command key of the MDI 5 is pressed, the contents of the %CRT image register 16 are displayed on the CRT display 6, and when the interface use command key is not pressed, the CRT display 6 displays data related to the numerical control device, for example. Displays the cannibal program, tool path, etc. If the interface processor f7 writes the program it manages to the CRT image register 13 when, for example, the program key PROG in the MDIS is pressed, the contents can be displayed on the CRTH display 6. I can do it.

As described in detail, according to the present invention, there is an MDI image register that receives MDI key information sent from an NC processor, and an MDI image register that corresponds to the type of key information received by this register. The numerical control device is equipped with a processing means for performing processing, such as reading machine tool status information, and a CRT image register for transmitting the information obtained by this processing means to the NC processor as CRT display information. Using the MDI, it is possible to display various information from the machine tool on the CRT H indicator provided on the numerical control device side. Further, since a CRT H display is used, there is an advantage that a sufficient amount of data can be displayed.
