The input device 1 has function keys, character keys, ten keys, cursor keys, and other control keys.
In the case of this embodiment, the function allocation to the function keys is as shown in FIG. 2, and the function can be selected by the combination of the function key and the up / down keys (not shown). In the example of FIG. 2, selecting the upper side of the F6 key enters the intermediate code input mode. This intermediate code input mode can be selected by various designations.

An example of the soft key menu displayed on the part program editing screen is shown in FIGS. 3 and 4. The menu has a hierarchical structure. First, in FIG. 3, as a basic menu as the first main menu displayed, 0 ... Positioning, 1 ... Linear interpolation, 2 ... Cutting related, 3 ... Correction / offset, 4 ... Program control, 5 ... Machine control, 6 ... Milling pattern, 7 ... Hole machining pattern, 8 ... Hole position pattern can be selected. The operator selects one of the basic menu items by keying in. 2 here
The cutting-related item of shall be selected.

FIG. 4 shows an example of an item menu selected from the main menu. As an item menu for intermediate codes related to cutting, 2.0 circular interpolation / right, 2.1 circular interpolation / left, 2.2 Thread cutting, 2.3 machine coordinate positioning, 2.4 absolute coordinate, 2/5 relative coordinate, 2.6 dwell can be selected. Here, circular interpolation / right is selected.

These intermediate codes are stored in the intermediate code storage unit 3.
Is defined as an intermediate code definition table in
The code and the corresponding intermediate code are stored as a pair.

On the other hand, the editing unit 2 transfers a copy of the G code data of the line where the cursor currently being edited is present to the interactive programming function unit 5. The interactive programming function unit 5 analyzes the data of the current cursor line transferred from the editing unit 2 (FIG. 7, step S101), associates this target data with a predefined keyword, and programs according to the programming procedure rule. Is to do. Here, the programming procedure rule is a program that defines the programming procedure, and is described by a programming language developed for creating the man-machine interface function of the numerical control device. This rule is stored in the storage unit 8 in advance, as described above.

When the line being edited (cursor line) has a G code and the intermediate code input mode is designated, the intermediate code storage unit 3 is referred to and a search is performed according to a predetermined rule using the G code as a key. Do (Step S10
2) It is checked whether there is a command supported by the intermediate code at the cursor line (step S10).
3) If there is a supported command, an illustration showing the meaning of the intermediate code specified in the interactive programming column on the display device and an input column for necessary numerical parameters are immediately displayed (step S105).

On the other hand, when there is no command supported by the intermediate code on the cursor line, a menu is displayed on the display device and the item (intermediate code) is selected after waiting for the operator's input (step S104). As a result, a diagram and a parameter input field regarding the selected intermediate code are displayed in the interactive programming field on the display device (step S105).

Then, the program block using the intermediate code having each value of the parameter determined by the key input by the operator is written in the cursor line of the part program being edited (step S106).

FIG. 5 shows an example of the interactive programming column, which is an intermediate code "circular interpolation right" (G code "G02").
Equivalent to). The operator can set the value of each parameter by key input while confirming the meaning by referring to the illustration showing the definition of circular interpolation displayed in the center of the right column. The parameters include X, Y, Z of target position coordinates and radius R of an arc to be interpolated. By selecting these input fields with a cursor and inputting a numerical value, an intermediate code, for example, an intermediate code is used. Machining program block (eg "Circular interpolation right X100Y200Z
10R50 ... "Is inserted or overwritten at the cursor position of the program being edited. Such an intermediate code can be output by pressing the F9 key.

A normal program block using the G code without using the intermediate code (eg "G02X100Y2")
00Z10R50 ... "
It can be output with the 10 key.

On the other hand, when there is no command supported by the cursor line intermediate code, a menu listing available intermediate codes is displayed, and the operator selects a desired code by key input. An example of the part program created by the present invention is shown in FIG. The part program completed in this way is stored in the storage unit 8.

The above processing is executed by a program. FIG. 8 shows a program for the process of FIG. 7, FIG. 9 shows a subroutine program for searching and displaying an illustration for the selected code, and FIG. 10 shows a subroutine program for displaying a numerical value input field.

As described above, the control unit 9 controls the drive unit 10 such as a step motor to operate the machine 11 according to this part program, but the intermediate code is also referred to when the program is executed. That is, since the control unit 9 interprets the intermediate code in the part program to be executed as a normal command, it refers to the intermediate code storage unit 3.

Next, the rule analysis section 6 will be described.
Based on the command from the input unit 1, the intermediate code definition table, the interactive programming procedure rules and the display content data extracted from the storage unit 8 are analyzed by the rule analysis unit 6 and converted into an internal format that can be executed by the numerical control device. (Compile) is performed. At the time of this conversion, the programming procedure rule is checked for grammatical errors and data errors, and if there is no error, the converted rule is stored in the rule storage unit 7. If an error is found during conversion, a message to that effect is displayed and the analysis process is stopped.

The intermediate code definition table, the interactive programming procedure rule, and the display content data can be created not only inside the numerical control device but also outside. Therefore, it is possible to analyze the rule analysis unit 6 by using the data transferred from the external personal computer system 13 by the floppy disk via the floppy disk device 12 or the communication line.

As described above, according to the present embodiment, the instructor can freely set the interactive programming procedure rule and the display content data according to the skill acquisition degree of the operator and the object to be processed, so that the detailed education is possible. It can be performed.

Since a machine-specific command code can be defined and registered, the intermediate code can be used even when a new function is added to the machine or the number of usable command codes increases. Can be freely defined and defined.

Further, the efficiency of creating the NC program can be improved by devising a method of collecting frequently used commands in a menu.
