Abstract

PROBLEM TO BE SOLVED: To provide an NC information editing device which makes it possible to intuitively understand in what process generated NC information is constituted, without a trouble to describe characters constituting an NC program language, one by one. SOLUTION: A menu of graphic symbols representing individual processes constituting an NC machining stored in a graphic symbol menu storage part 2 is displayed on a display device 7. An operator who looks at the displayed menu operates input devices 5 such as a mouse and a keyboard to select graphic symbols indicating necessary processes in sequence and also specifies operation contents corresponding to respective graphic symbol kinds. Consequently, the graphic symbols for machining having the operation contents specified are stored in a machining graphic symbol storage part 3. A CPU 1 converts data of the graphic symbols for the machining into NC information according to a conversion rule stored in an NC information conversion rule storage part 9 in response to an indication for conversion to NC information and stores it in an NC information storage part 8.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for inputting data relating to an NC processing step and editing NC information.

[0002]

2. Description of the Related Art In a conventional NC information editing apparatus, an NC program language expressed by characters and numerals is described in an NC program.
The method of creating C information is adopted. In the NC programming language, a combination of several characters is used as one language, and each language represents each operation of the NC machine tool. Therefore, when actually creating, NC
This is a very cumbersome task because you have to enter the characters that make up the programming language one by one. Furthermore, it is very difficult to intuitively grasp what kind of process this processing is composed of just by looking at the created NC program. Of course, the NC program language has a subprogram function, and if a subprogram is prepared for each process, the trouble of inputting the NC program language for each operation can be omitted. You still have to enter the characters that make up the programming language one by one. Furthermore,
To actually use a subprogram, a deep understanding of the NC programming language is required.

FIG. 3 shows an example of an NC program described in a conventional NC information editing apparatus. In this example,
It is described that machining is performed in the order of mounting and preparing a tool, milling, exchanging a tool, drilling four places, drilling one place, and storing a tool. As you can see in this example,
If you do not enter many characters, the NC program will not be completed. Writing an NC program requires considerable effort. In addition, it is quite difficult to understand the contents of machining from the NC program described in this way.

[0004] On the other hand, automatic programming devices have become widespread in order to facilitate creation of NC programs. If an automatic programming device is used, it is not necessary to directly write an NC program, and the contents of machining can be performed by checking the contents input to the automatic programming device. However, with an automatic programming device, the machining sequence and the operation details of the tool are automatically determined inside the device,
It is difficult for the operator to intervene in the contents. If there is a problem with the operation, the NC program language output by the automatic programming device is analyzed in what steps it is composed of and how it operates, and then the characters that constitute the NC program language are analyzed. It is necessary to describe each one and make changes. As a result, not only knowledge of the NC program is required, but also time is required for the analysis work.

[0005]

As described above, in the conventional NC division editing apparatus, it takes considerable time to describe an NC program, and it is difficult to understand the processing contents from the described NC program. There was a problem that it was quite difficult. These problems can be solved to some extent by using an automatic programming device. However, if there is a problem in the automatically determined machining sequence or the operation of the tool, NC
Since it is necessary to analyze and change the program itself, there has been a problem that a considerable amount of time is required for the analysis and modification work.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to reduce the number of characters constituting an NC program language required by a conventional NC information editing apparatus. There is no need to write each one,
An object of the present invention is to provide an NC information editing apparatus that allows the user to intuitively understand what kind of process the created NC information is composed of. Further, an object of the present invention is to enable a user to easily grasp and analyze machining contents without needing knowledge of the NC program even when an operation problem occurs during operation, and to set a machining operation. Another object of the present invention is to provide an NC information editing apparatus capable of easily changing the order and the operation contents of a tool.

FIG. 2 shows a screen display example of the NC information editing apparatus according to the present invention. Part A is a part of the contents of the graphic symbol menu storage unit 2 displayed. The part B is the one in which the contents of the graphic symbol storage for processing 3 are displayed. From this display, it is easy to intuitively grasp the contents of the machining, and it is easily understood that this is completely different from the conventional method in which the machining contents must be grasped from the NC program shown in FIG.

An example of a specific operation will be described with reference to FIG. In this example, the operation is performed in such an image that cards on which pictures of the contents of the process are drawn are arranged on a desk. Initially, the contents of the graphic symbol menu storage unit 2 are displayed on the display device as a process menu of selectable graphic symbols. (A in FIG. 2) On the other hand, nothing is stored in the processing graphic symbol storage unit 3, and a position (B in FIG. 2) of the symbolic NC program indicating the contents of the processing graphic symbol storage unit is not stored. Is also not displayed.

The operator arranges graphic symbols in accordance with the operation at the time of processing. The first of the machining operations is the mounting of a tool. The operator uses the mouse or the like to select a “tool change” menu from the graphic symbol process menu (A in FIG. 2), and arranges the menu at the head position of the symbolic NC program (B in FIG. 2), and at the same time, the operation details. input. In this case, face mill T
1 is mounted on the spindle, and a drill T3 is prepared. At the time of input, an input field for each symbol or an input field for the designated symbol is displayed in a window (FIG. 2).
C, D), and an operation mode such as inputting detailed operation data in this window is conceivable. As a result of this operation, the graphic graphic symbol for processing, whose operation content is specified, is stored in the processing graphic symbol storage unit 3 so that the operation order can be recognized, and at the same time, a graphic display corresponding to the operation content is performed. . In the case of a tool change, the presence / absence of the currently mounted tool, the replaced tool and the ready tool, and the tool shape indicating the type of tool are graphically displayed based on the data of the mounted tool and the prepared tool. By such a graphic display, the contents of the operation data can be understood at a glance. Of course, the operation data for each graphic symbol may be input after the graphic symbols are arranged.

Next, in order to perform actual milling,
The operator selects the "milling" menu from the graphic symbol process menu (A in FIG. 2), arranges it in the second position of the symbolic NC program (B in FIG. 2), and simultaneously inputs the operation details. In this example, the shape of the region to be milled is input, and the shape is graphically displayed. Thereafter, graphic symbols are arranged in the same procedure, and the entire processing content is designated. The specified result is graphically displayed on the display device, so that it is possible to easily understand what kind of processing is performed and what kind of process is performed. At the same time, the graphic symbol storage unit 3 stores the graphic symbols of the entire processing contents for which the operation contents are specified so that the operation order can be recognized.

Thereafter, when the operator performs an operation for creating NC information, the data stored in the graphic graphic storage for processing 3 is converted into NC information.
It can be used for actual processing. When it is desired to change the processing order or the operation content of the tool set in the NC information, the processing graphic symbol stored in the NC information storage unit 8 (FIG.
B) is displayed, and if the relevant part is changed by a rearrangement operation of the processing graphic symbol or an instruction to change the operation content, and an instruction to convert to the NC information is issued, the NC information or the NC information is changed based on the changed data. Regenerated.

[0015]

As described above, according to the present invention, it is possible to create NC information with an image in which menus displaying the contents of processes are displayed graphically on a display device. There is no need to describe each character of the NC programming language required by the device one by one, and an editing operation that can intuitively understand what process the created NC information is composed of is performed. Will be possible. On the other hand, since the operator can easily intervene in the processing sequence and the operation contents of the tool as compared with a conventional automatic programming device or the like, the NC information can be easily changed. Furthermore, in the present invention, detailed operation contents input for each graphic symbol are graphically displayed on the graphic symbol, so that it is easier to grasp the processing contents.
