Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a numerical control device (NC device) having a guidance function, and more particularly to a numerical control device for displaying guidance when an operator creates a part program.

[0002]

BACKGROUND ART Conventionally, when operating a machine tool,
A numerical controller is used to control the operation. This numerical control device controls the operation of a machine tool based on a part program indicating the shape of a part to be machined and a machining method such as cutting. In order to improve the man-machine interface, if you press the help key etc. provided on the input device panel of the numerical control device in this numerical control device, guidance for operating methods and part programs will be displayed on the liquid crystal panel, CRT display, etc. Some were displayed on the display of.

[0003]

However, the conventional guidance content is that the numerical controller manufacturer (NC manufacturer)
It was created by and is not flexible because it cannot be changed by the operator (user) side, and it was not very useful for the field using the numerical control device. That is, it is difficult for an NC maker who creates the guidance to create the guidance individually according to the usage state of each user. Therefore, the guidance is created only for the basic functions common to each site. Was there. For example, the same machine tool may have different accessories and the like. In this case, the machine auxiliary code and the like used in the part program also have codes that can and cannot be used by each machine. Therefore, in order not to use the unusable code by mistake, the guidance for these codes, etc. could be created only for the ones that can be commonly used by each machine, that is, the basic functions. . On the other hand, it is not the basic function that the operator needs the guidance at the actual site, but it is often for the special contents unique to each site or each machine. Therefore, the guidance created by the conventional NC manufacturer is required. Then there was a problem that it was almost useless.

Further, in recent years, various types of small-quantity production have been demanded, and it is necessary to create many types of part programs that utilize machining of workpieces. Even if a special order is made to an NC maker or the like, guidance according to the site is provided. Even if you create
There was also the problem that the guidance could not be fully applied to many part programs that were created one after another.

An object of the present invention is to provide a numerical control device with a guidance function, which can display guidance corresponding to each machine at each site and can improve the work efficiency when an operator edits a part program. .

[0006]

According to the present invention, there is provided an input section for inputting a part program, an editing section for editing the part program based on the input from the input section, and a display section for displaying the part program being edited. A numerical control device with a guidance function, comprising: a guidance creating unit for displaying a predetermined guidance on the display unit; a guidance storing unit for storing guidance rules and guidance data used by the guidance creating unit; A guidance program analysis unit for converting guidance rules and guidance data input from an input unit or an external device into a format that can be used by a numerical control device and storing the converted guidance data in the guidance storage unit.

Here, the guidance rule is a program that defines a guidance procedure. For example, when a predetermined help key or the like is pressed at the time of editing the part program, the program command at the cursor position is read,
This is a procedure for comparing with a predetermined keyword and displaying the guidance data corresponding to the keyword when the corresponding keyword is present. In addition, the guidance data is the description display contents such as the explanatory text and the graphic displayed according to the guidance rule.

[0008]

In the present invention as described above, the operator or the like at each site inputs the guidance rule and the guidance data corresponding to each machine in advance by using the input unit of the numerical controller or the external device such as the personal computer. . At this time, the guidance rule and the data are created using a predetermined programming language. The guidance rules and data are converted into guidance rules and data in an internal format corresponding to the hardware of each numerical control device by the guidance program analysis unit provided in the numerical control device, and recorded in the guidance recording unit.

In the numerical controller with the above settings, when the operator gives an instruction to give guidance while creating a part program, the guidance creating section causes the guidance rule and the guidance rule stored in the guidance recording section. A predetermined guidance is displayed on the display unit using the data. Therefore, based on the guidance rules and data created by the operator or the like, it is possible to display appropriate guidance corresponding to each machine at each site, and the utility value of the guidance operation is increased. Therefore, if the operator uses the guidance when creating the part program,
Guidance with appropriate content is displayed, improving work efficiency. In addition, by equipping the numerical control devices with different hardware configurations and software system configurations with the guidance program analysis unit that matches their specifications, the same type of guidance rules and data can be used for different numerical control devices of different models. It is also possible to transplant to.

In the numerical controller 1, the guidance program 10 which is input and edited by the input unit 2 and the editing unit 3 in the same manner as the part program 4 and stored in the memory unit 5 is analyzed, and the guidance rule 11 and the guidance data 12 are stored. A guidance program analysis unit 13 for creating the rules, a guidance storage unit 14 for storing the rules 11 and the data 12 created by the analysis unit 13, and a predetermined guidance on the display unit 9 based on the stored rules 11 and the data 12. And a guidance creating section 15 for displaying.

FIG. 2 shows an example of the display unit 9 of the numerical controller 1 with a guidance function. In the numerical controller 1 according to the present embodiment, the input unit 2 is provided adjacent to the display unit 9 to form a panel. The display unit 9 has a display screen 2
0 and a soft key 21 arranged below the display screen 20.
It has and. The display screen 20 is divided into a main screen display area 22 and a soft menu display area 23 from the top.

The main screen display area 22 is a part program 4
The guidance program 10 is displayed, and the operator inputs and edits each program from the input unit 2 while watching the display in the display area 22. As shown in the enlarged view of FIG. 3, the soft menu display area 23 is divided corresponding to the F1 to F8 keys of the soft key 21, and
The part corresponding to the F1 to F7 keys is divided into two stages, upper and lower. With regard to F1 to F7, by pressing the up and down keys to select the upper side or the lower side and then pressing F1 to F7, the processing of the items displayed in each is executed. Regardless of whether the F8 key is the up or down key, regardless of whether the upper side or the lower side is selected, the process of ending the program editing is executed.

Next, the operation of this embodiment will be described. First, before creating the part program 4, the guidance program 10 corresponding to each numerical controller 1 is created. Like the part program 4, the guidance program 10 is created by the input unit 2 and the editing unit 3 and stored in the memory unit 5. FIG. 4 shows an example of the guidance program 10. In the guidance program 10, a guidance rule 11 that describes a procedure for displaying guidance and guidance data 12 that is displayed on the display unit 9 based on the guidance rule 11 are described in a predetermined programming language.

After creating such a guidance program 10 and storing it in the memory unit 5, the operator analyzes the guidance analysis from the input unit 2 to the guidance program analysis unit 1.
3 is issued, the guidance program analysis unit 13
According to the guidance analysis flow shown in FIG. 5, the guidance program 10 is separated and converted into the guidance rule 11 and the guidance data 12, and stored in the guidance storage unit 14. That is, when the guidance analysis is ordered,
First, the operator designates the program 10 to be converted from the plurality of guidance programs 10 stored in the memory unit 5 from the input unit 2 (process S51).

The guidance program analysis unit 13 reads out the designated program 10 from the memory unit 5 and converts it into an internal format that can be executed by the numerical controller 1 (process S5).
2). During the conversion work, it is determined whether or not the program 10 has a grammatical error or a data error (process S53). If there is an error, an error is displayed on the display unit 9 and the analysis flow ends (process S54). ). On the other hand, if there is no error, the program 10 converted into the internal format is divided into the guidance rule 11 and the guidance data 12 (process S55), and these are stored in the guidance storage unit 14 (process S56). The above guidance program conversion processing is performed by a plurality of guidance programs 10 as necessary.
To complete the preparatory work.

Next, the guidance display process when the operator is creating the part program 4 will be described. When the guidance is displayed while the part program 4 is being created, the guidance mode is specified by pressing the F5 key with the soft key menu display area 23 set to the upper side. The guidance mode is canceled by pressing the F5 key again.

When the guidance mode is designated by the operator, the editing section 3 passes a copy of the data of the current cursor line to the guidance creating section 15. The guidance creating unit 15 performs guidance display processing based on the passed data, based on the guidance display flow shown in FIG. That is, the guidance creating unit 15 analyzes the data of the cursor line passed from the editing unit 3 and reads a predetermined command as guidance target data (process S61). That is, the data on the cursor line may include not only the command of the part program but also a parameter indicating the coordinate position and the like. Therefore, data analysis is performed so that the guidance target data is only the command.

Next, this target data is made to correspond to the keyword set based on the guidance rule 11 of the guidance storage unit 14, and it is searched whether or not there is a corresponding keyword (process S62). For example, in the guidance rule 11 shown in FIG. 4, the first character of the target data is “G, M,
It is checked whether or not it corresponds to a set character such as “T, ...”, and if so, whether or not the next number of the character corresponds to the set number. That is, whether or not the target data is a predetermined command of the part program such as "G00, G01, ... G81, ... M00, ... T00, ..." Can be searched from the set keywords. Is determined (process S63).

When the target data can be retrieved, a predetermined guidance corresponding to the data is displayed on the display unit 9
Is displayed (step S64). At this time, the guidance is displayed as a popup window 71 in the main editing area of the display unit 9, as shown in FIG. For example, when the guidance is instructed by pressing F5 while the cursor is located on the first line of the part program 4 displayed in FIG. 7, the guidance corresponding to the keyword “WORK123” as shown in FIG. "Work No.123 Machining tool list"
Is displayed. When a guidance instruction is given in the third line of part program 4 in FIG. 7, “drill cycle / G81” which is the guidance corresponding to the keyword “G81” is displayed as shown in FIG. , G81 Displays parameters such as hole positions used for commands and their figures.

Such a guidance display is provided in the guidance rule 11 by the guidance display program "ELSDSPD (G00), ... ELSDSPD (Gn)" which is executed for each keyword.
Is done by. Each guidance display program displays the guidance data 12 as shown in FIG. 4, for example, on the display unit 9. The guidance data 12 in FIG. 4 is a part of the screen display command executed by "ELSDSPD (G00)" when the keyword is "G00", and the first half part is a command group 12A for displaying a guidance character string for guidance. The latter half is a command group 12B for drawing an illustration for guidance.

On the other hand, if the target data does not correspond to the set keyword and the search cannot be performed, a message indicating no data is displayed on the display unit 9 (step S65), and the process ends.

According to the present embodiment as described above, the guidance content used when creating the part program 4 can be freely set by the operator who is the user creating the guidance program 10. Therefore, the guidance can be set for each numerical control device 1 arranged at each site, and the appropriate guidance display suitable for the site where the actual work is performed can be performed, so that the workability at the time of creating the part program 4 can be improved and the operator The proficiency level of can be improved quickly. In particular, since guidance can be displayed even for a portion peculiar to the numerical control device 1 at each site, work efficiency can be significantly improved as compared with the related art.

Since the guidance program 10 for setting the guidance is created in a predetermined programming language, the operator can create and implement the necessary guidance function by learning this programming language. . Further, the guidance program 10 is created using a predetermined programming language, and each numerical control device 1 is provided with a guidance program analysis unit 13 for converting the guidance program 10 into an internal format usable by each numerical control device 1. The created guidance program 10 is used by another numerical control device 1 having a different hardware configuration or software system configuration.
It can be easily ported to and can be compatible with multiple models.

It should be noted that the present invention is not limited to the above-described embodiments, but includes modifications and improvements as long as the object of the present invention can be achieved. For example, although the guidance program 10 is created by using the input unit 2 and the editing unit 3 of the numerical controller 1 in the same manner as the part program 4 in the above-described embodiment, as shown in FIG.
