is a drive unit for driving the machine tool 6t based on information from the control unit 4. T is a setting display section that displays the processing information of the input section 2 and allows you to input corrections and changes if necessary; 8 is a setting display section in which the fixed pattern of the guidance message to be displayed on the setting display section 7 is displayed. , the memorized message table appears.

Next, the operation will be explained. An input medium 1, for example a paper tape, containing machine coordinate values, cutting speed, and other instruction information is read by an input unit 2. When the read command information is analyzed in the calculation section 3, it is sent to the control section 4, and the accurate position control of the machine tool 6 is performed via the drive section 5.

At this time, if the user of the machine 1 wants to modify the data to be executed next based on the command information inputted from the input medium 1, he or she modifies the data from the setting display section 7.

In the setting display section T, when the command code is set,
Based on the code number, the corresponding command format is searched in the table and displayed as a guidance message. The operator modifies the command information according to this command format. The corrected data is again
Once read by the input unit 2, operation of the machine tool 6 can be continued.

[Problem that the invention seeks to solve]

Conventional numerical control devices are configured as described above, so the contents of programming guidance messages are as follows:
The display was limited to a fixed pattern, and the person who damaged the 2-seat machine could not change it.

This guidance message is also a command code.

Since only the addresses used for the code were displayed, the meaning of each address was unclear and was insufficient as a guidance message.

This invention was made to solve the above-mentioned problems, and it is possible to display guidance messages that can be used more effectively during programming, and also allows the operator to freely change the contents of the guidance messages. ,
The purpose is to obtain a numerical control method that can be changed, modified, deleted, and added.

[Means for solving problems]

The numerical control method Fi according to the present invention stores guidance message data during programming in the area where normal Kanji programming is stored, and also sets the message data in kanji and codes according to the Kata code table. Then, it can be converted to kanji or kataji and displayed.

[Effect]

The numerical control method according to the second aspect of the present invention can be stored in the memory in which a normal machining program is stored, so it is possible to increase the capacity of the conventional message table, and it is not limited to fixed patterns. A number of address message patterns can be stored for each command code.

In addition, the editing function provided by the numerical control device allows corrections to be made using the display function in the same way as normal machining programs, and the message data stored in the memory can be rewritten.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a block diagram showing a schematic configuration of one embodiment. 1a
1b is a paper tape which is a processing information input medium, and 1b is a memory which is also a processing information input medium, but the data stored therein is used.

1 is a machine tool, T is a setting display section, and these components have the same configuration as the prior art. This embodiment is characterized in that the data of the guidance message displayed on the setting display section T is stored in the memory 1b in which processing information is stored, thereby forming a message table 8.

In FIG. 2, reference numeral 9 denotes a correction buffer provided to accomplish the editing function of the numerical control device. The data in Memo+JIb displayed on the setting display section 7 is edited via this correction buffer 9. This correction buffer 9t is also used to correct data in the message table 8.
- done through.

Next, the operation will be explained. In FIG.

When processing information is read into the input section 2 from the paper tape 1a or the memory 1b, it is sent to the calculation section 3 and analyzed. Then,
The signal is sent to the control section 4, and accurate position control of the machine tool 6 is performed via the drive section 5t.

At this time, with the processing information read into the input section 2.

If the machine operator wishes to modify the data to be executed next, the machine operator modifies the data using the setting display section 7. first,
In the setting display section T, when a command code is set by the operator, the command format corresponding to the code number is searched in the message table 8 and displayed as a guidance message. Next, the operator modifies the command information according to this command format. When the corrected data is read into the input unit 2 again, operation of the machine tool 6 can be continued.

Since this message table 8 is located in the same memory 1b as the normal machining program, it is created by the same operations as for the machining program. That is, the settings are stored in the memory 1b by inputting them directly from the setting display section 7 manually, or by inputting them from a paper tape using a tape reader.

Next, modification of the message table 8 stored in the memory 1b will be explained with reference to FIG.

First, the operation of the editing function of the numerical control device with respect to the machining program is as follows. The machining program to be edited is read from the processor 1b into the correction buffer 9, and its contents are displayed on the setting display section 7. The operator performs necessary edits such as changes, corrections, deletions, and additions to the displayed data. When the edited data is received by the correction buffer 9, it is transferred to the memory 1.
The contents of the correction buffer 9 are written to the correct processing program in b, and the first editing is completed. Therefore message table 8
The contents of can also be displayed on the setting display section T via the correction buffer 9 and edited using this editing function.

2. In the above embodiment, when operating the machine tool, input from the paper tape 1a or the memory 1b to the input unit 2,
Although we have explained the case of modifying machining information, the guidance method is also effective when editing a machining program that is not currently running, or when creating a new machining program on t-c RT, so in this case The above embodiment also produces similar effects.

In addition, the data displayed as messages was shown to be converted into kanji and kana codes, but messages are not limited to characters; graphic displays are often more effective; It may be configured to perform conversion.
