Abstract

PROBLEM TO BE SOLVED: To prevent mistransfer, minimize the frequency of setup operation, and improve the operation rate of an NC machine tool while shortening the operation time of an operator by automatically referring to machining shape data, etc., and judging whether or not NC data need to be regenerated, and automatically actuating a CAM system and generating the latest NC data. SOLUTION: The NC data management system takes production instruction information meeting necessary conditions out of registered production instruction information and lists and displays it on a screen (S1), selects transfer NC data out of the displayed list (S2), and then transfers the transfer NC data (S3). The generation date and time of a machining shape data file taken out of a file of index information as management information of the transferred NC data is compared with the generation date and time of an NC data file and when the generation date and time of the machining shape data file is older, the CAM is actuated to update the NC data.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an NC data management system for managing and operating NC data transferred to an NC machine.

[0002]

2. Description of the Related Art A conventional NC data management system includes a CA.
The NC data created by the M system is stored in corresponding figure numbers. This system uses CAM
Re-creation of NC data by the CAM system prior to machining, such as when machining shape data, which is input data to the system, is changed, or when CAM parameters (machining conditions, tools to be used, etc.) are changed when executing CAM However, the manual operation of activating the CAM system and the re-registration operation of the NC data are required when the CAM system is required.

In order to transfer NC data to an NC machine tool as an operation of an actual NC data management system, an operator inputs a drawing number and changes the NC data corresponding to the designated drawing number from the registered NC data. As described above, the operator determines whether the transferred data is the NC data created from the latest machining drawing, that is, the machining shape data, or the NC data reflecting the change of the CAM parameter, as described above. Needed.

[0004] Further, the input of the figure number is performed based on production instruction information for a processing site, and is created by a production management system or the like operated separately from the NC data management system. For this reason, the operator has been working while separately grasping the necessary number of the work pieces from the production instruction information. Then, since the NC data to be used in the machining is naturally created so as to perform machining for one machined work, the necessary number of machinings is performed by the operator by starting the NC machine tool a number of times corresponding to the number. I was going.

[0005] Further, as described above, N
Since the C data is managed, when transferring all the figure numbers constituting the serial number (corresponding to necessary parts for the target product), the operator inputs all the figure numbers constituting the relevant serial number individually. The transfer was going on. In addition, if the material of the target work of the NC machine tool is different, a large amount of labor is required for a setup work such as replacement of a processing tool or a jig, or replacement of a supply material in the case of cutting a plurality of works from the same material. Therefore, it is desirable to continuously transfer NC data in which the material of the work is unified as much as possible.

However, since the NC data and the material information of the work are not managed together, the operator selects the target drawing number with reference to the above-mentioned production instruction information and transfers the data.

[0007]

In the conventional NC data management system, it is checked whether the NC data is created from the latest machining shape or whether it is created based on the latest CAM parameters (machining conditions, tools used, etc.). Since it was manually performed, the confirmation work was troublesome and there was a possibility that the old NC data could be processed as it was due to a confirmation error. If it is determined by the check that the NC data needs to be updated, it is necessary to manually start the CAM system and perform the NC data creation operation and the registration operation. , And it requires a lot of operation time.

Further, when the same work is continuously processed by the required number, the operator performs the continuous processing using the NC data of one work after grasping the required number from the production instruction information. The number of startup operations required for the required number of workpieces is required for the NC machine tool, and the time required for the operator to operate the NC machine tool becomes longer, which has been an obstacle in managing a plurality of NC machine tools. . Furthermore, it is not possible to perform batch transfer of NC data of all drawing numbers constituting a production number or batch transfer of NC data in which work materials are unified, and input necessary drawing numbers one by one by referring to production instruction information. Therefore, there is a problem that a large amount of operation time is required and a transfer error is likely to occur.

As described above, the conventional NC data management system requires a large amount of operation time such as checking and investigating work performed by an operator, such as checking NC data and referring to production instruction information, and recreating and transferring NC data. There is a problem that it takes time and an operation error by an operator is likely to occur. Furthermore, when processing the same material with priority, it is difficult for the operator to select the processing of the same material from all the production instruction information and perform the transfer operation. As a result, the material must be changed more than necessary. May occur, NC
Since the number of setup operations such as replacement of a processing tool or a jig with respect to a machine tool increases, the operating rate of the NC processing machine may be reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and improves the operating rate of an NC machine tool by shortening the operation time of an operator, preventing transfer errors, and minimizing the number of setup operations. It is to provide an NC data management system capable of doing so.

[0011]

The NC data management system according to the present invention is characterized in that the NC data is referred to automatically by referring to the machining shape data and CAM parameters without checking the NC data by an operator. It is characterized by the function of judging whether it is necessary to re-create, and if necessary, automatically starting the CAM system to create the latest NC data and re-register. According to this method, the latest NC data can be transferred to the processing machine without the operator performing an NC data check operation. NC
Since the data is automatically updated, the operator does not need to perform a CAM system start-up operation, an NC data creation operation, a registration operation, and the like, so that the operation time of the operator can be greatly reduced.

According to the second aspect of the present invention, by controlling the NC data management system in association with the production instruction information, the required number of target workpieces can be automatically grasped and the NC can be executed continuously. It has the feature of automatically re-editing and transferring data. That is, when a plurality of the same workpieces are required, the NC machine tool needs only one start operation because the necessary number of NC data for continuous machining is added and transferred at the time of the transfer work by the operator, and the operator is required to perform the NC operation. It is possible to reduce the time allotted to the operation of the machine tool. In addition, in the above operation, the additional processing for the NC data is automatically performed without any manual operation, and thus there is an effect of preventing an error in the number of processed data.

Further, according to the third and fourth aspects, it is characterized in that the NC data of the drawing number constituting the serial number and the NC data of the work of the same material can be collectively and continuously transferred. Then, since the production instruction information is managed inside the NC data management system, the serial number of the drawing number constituting the designated serial number can be easily transferred without the operator referring to the production instruction information, Reduce transfer operation time and prevent operation mistakes. In addition, continuous transfer of unified work materials can be easily performed, shortening the operation time and reducing NC time.
Achieve an improved operating rate by reducing the number of machine tool setups.

According to the fifth aspect, since all of the constitutions of the first to fourth aspects are provided, compared with the related art,
It is possible to significantly reduce the operation time required for updating NC data, transmitting NC data, and starting the NC machine tool, and to improve the operation rate by reducing the number of setups of the NC machine tool. Become.

The drawing data of the workpiece to be machined created on the CAD system is output as a machining shape data file (a) and is input to the CAM system (b). CA
Information on the newly created machining shape data and the changed machining shape data on the D system is registered in the NC data index file (e).

The CAM system takes in the machining shape data file and the NC data creation conditions of the CAM parameter file (c), generates NC data and creates an NC data file (g). At this time, the file name and date and time of the created NC data are registered in the NC data index file (f). The CAM parameter file used when creating the NC data can be edited by the CAM parameter editing system (d).

In the NC data management system, the NC data index file is referenced (h), the NC data file is changed (i) and acquired (j). The detailed configuration of the file group and the system group shown in this configuration diagram will not be described, but the configuration is not limited to the same computer.
Alternatively, a configuration in which the remote system is distributed on the remote system via N may be used. FIG. 6 is an example of an operation screen of the NC data management system. The list on the screen is for one NC machine tool.
The production instruction contents are generally arranged in the order of the production schedule, and one line of the list is processing one part (ie, one NC data).
The screen can be updated in page units up to the maximum instruction of the production instruction. In the list, the highlighted line (top line) indicates the current position (cursor), and the highlighted display is moved up and down by the cursor movement function assigned to the specified key on the keyboard (eg, [↑] [↓] key). It is configured to move to indicate the current position.

The operator uses this function to select NC data to be processed from a list. The selection operation is performed by pressing a specified key (e.g., [Enter] key) on the keyboard to select the NC data being highlighted and displayed, as in the single selection function, and a specified key on the keyboard (e.g., [Home] key). By pressing, a batch selection function for selecting all the NC data in this list is prepared, and the selected NC data is transferred to the NC machine by the transfer function assigned to the function key, such as F10 "Transfer" shown in the lower part of FIG. It is configured to transfer to a machine.

Also, the display items of the list can be changed by the function keys F1 to F3 shown in the lower part of FIG. 6, and an operation example when F1 "designated serial number display" is performed is shown in FIG. FIG. 8 shows a screen display example after that. FIG. 9 shows an example of operation when F2 “designated material display” is performed, and FIG. 10 shows an example of screen display after the operation.

In addition to the above, a repetition control section (3, 4, 6) for performing continuous machining for the required number of times is added. The repetition control section includes a required number of times description section 3, a counter declaration section 4 for counting the required number of times, and a loop end determination section 6 for determining the end of the loop. Note that the description of the repetition control portion uses a macro instruction executed by the NC control device, and the function and description method differ depending on the target NC machine tool, but the configuration is substantially the same.

From the step S3064, a new NC data is created, the current date and time is extracted from the OS, the NC data creation date of the NC data index file is updated to the extracted value, and the current value is changed to the current value. Be composed.

Also, S307 "addition of number information" shown in FIG. 3 includes S3071 for extracting the required number from the production instruction information as shown in FIG. 5, and S307 for determining whether continuous machining should be performed.
3072 and S3 for extracting the NC data file name from the NC data index file when continuous machining is required
073 and S307 for opening the NC data file
S3075 that adds macro codes for continuous processing of the number of NC data to the NC data in the NC data;
And S3076 for closing the data.

The operation of the NC data management system configured as described above will be described based on the procedure. In the NC data management system shown in the present embodiment, the production instruction list shown in FIG. 6 is displayed as an initial screen, and the display order of the list is arranged in the order of production instructions (the order to start construction: the order of delivery date).
The production instruction list switching step of S1 is executed by pressing a function key on a keyboard.

For example, when the designated serial number display (F1 key) is selected, the answer is Yes in S104 of FIG. 2 and the serial number input window 1 shown in FIG. 7 is displayed (S106). Then, when the operator inputs a serial number from the keyboard (for example, “MB1020445”), only the production instruction information with the serial number “MB1020445” is extracted from the currently acquired production instruction information (S106), and the process returns to S102 and is acquired again. Display a list of production instruction information.

When the designated material display (F2 key) is selected, the determination in S104 is No, and the determination in S107 is Y.
The answer is es, and the material input window 2 is displayed as shown in FIG. 9 to enter the designated material input state (S108). Here, when the material (eg, “SS41”) of the target work is input, only the production instruction information of the material (eg, SS41) that matches the input material is acquired from the currently acquired production instruction information (S109). Returning to S102, the list is displayed again.

Further, when all display (F3 key) is selected, No is determined in both S104 and S107, and S110 is determined.
Is Yes. All the production instruction information is acquired from the production instruction information file (S101), and the process returns to S102 to redisplay a screen similar to the initial screen. The display switching functions may be executed in any order, and it is possible to limit the material after designating the serial number and vice versa.

In the transfer data selection step S2, the detailed processing procedure is not shown, but in the preceding step S1, the N is transferred to the NC machine tool based on the changed production instruction list.
This is the step of selecting C data. The selection operation includes a single selection function of selecting single NC data by pressing a specified key (eg, [Enter] key) on the keyboard, and a specified key (eg, [Home]) on the keyboard.
Pressing the key) executes a combination with a batch selection function for selecting all NC data in the list. For the selected NC data, the selection flag of the corresponding record in the production instruction information file is set to 1 (ON).

The list display in FIG. 6 and the production instruction information file correspond to each other on a one-to-one basis. When the third item in the list is selected, the corresponding record in the production instruction information file is changed. It can be identified (in the present embodiment, the third item corresponds to the third record).

In the subsequent transfer step S3, the NC data selected in the transfer data selection step S2, which is the preceding step, is transferred to the NC machine tool. In this step, F1
It is started by pressing the 0 key. Transfer step S3
As an example of the execution of, it is assumed that the NC data in the second row of the list shown in FIG. 6 has been selected, and a description will be given based on the flowchart of FIG. From the relationship between the list display and the production instruction information file described above, the record corresponding to the display of the selected second row (the selection flag is ON) is the second record.
The description will be made in the order of the flowchart of FIG.

First, the production instruction information file is opened (S301), and one record is read from the file (S301).
302). Since it is the first record, the selection flag of the read data is checked instead of the end of the file (No in S303) (S304). Since the selected record is the second record, the selection flag of the first record is "0" (OFF), the determination in S304 is NO, and the next record (second record) is read (S302).

This record is the record selected in step S2 as described above, and the selection flag is ON,
The determination at 304 is Yes, and NC data index information is extracted at S305. Although a detailed description of this process is omitted, as described in the configuration of the present embodiment, the NC information is obtained from the figure number information in the record of the production instruction information file.
NC corresponding to the corresponding figure number in the data index file
This is a step of extracting index information that is data management information.

The next step, NC data update step S306
Is a step of re-creating the latest NC data based on the extracted index information. Hereinafter, the procedure will be described based on FIG. 4 showing the details of the step S306. First, the creation date and time of the machining shape data file extracted from the NC data index file is compared with the NC data file creation date and time (S3061). This comparison is to check whether a design change or correction has occurred after the NC data creation / registration, and as a result, the machining shape data file which is the original data of the NC data has not been changed. If the creation date and time of the machining shape data file is older, S306
The determination of 1 is Yes, the CAM system is started, and NC is started.
Update data.

Although the details of the CAM system are not particularly described, when the CAM system is updated,
After rewriting the contents of the C data file, an update date is set for the NC data creation date and time of the NC data index file (corresponding to f and g in FIG. 15), and Return
n. If it is determined in step S3061 that the date on which the NC data is created is newer, the process proceeds to step S3061.
In step 3062, a creation date and time of a CAM parameter file for setting processing conditions and tools to be used when the CAM system is executed is acquired (this step is not described in detail, but file management information managed by the operating system based on the file name). Which is equivalent to k in FIG. 15).

Similarly, the NC data creation date and the CAM
If it is determined Yes in S3063 for comparing the creation dates of the parameter files, Yes in S3061
CAM system is started and NC
The data is updated (S3064). If the determination is No, the NC data is not updated and Return is performed. When the processing in FIG. 4 is completed, the process proceeds to the number information adding step S307, which is the next step in FIG.

The detailed processing procedure of S307 will be described with reference to FIG. First, in step S3071, the number of production instructions (required number) is acquired from the record of the production instruction information file acquired in step S302 in FIG. Next, it is determined in S3072 whether the required number is plural. Here, when the required number is only one, the number information is not added and the return is performed. When the number is more than one, the number information is added so that the required number is continuously processed with respect to the NC data in the following steps. Will be. As a subsequent procedure, an NC data file name is acquired from the index information acquired in the step S305 (S307).
3), open the NC data file (S307)
4).

Although the contents to be added are shown in the example of FIG. 11, if the data of the second row in the list of FIG. 6 is targeted as in the above description, the required number is two in FIG. It can be seen that there are [SV, VN
= 2]. 4 ([SV, VC =
0]) and 5 ([SV, VC, LT, VN, GO, -10
0]), a control amount for repeating processing a total of VN times (in this case, two times) is added (S3075). After the code is added according to the above procedure, the target NC data file is closed (S3076), and the process returns to step S307 in FIG. The NC data extracted by the above process and added with the number information is temporarily stored in the transfer buffer (S308).

The processing from S302 to S308 is processing for one record of the production instruction information file. Repeat the above process until the end of the file.
The NC data to be transferred is accumulated in the transfer buffer. When the end of the file has been reached (Yes in S303)
Transfers the contents of the transfer buffer to the NC machine tool,
A series of processes up to the transfer process 3 is completed. The processes from S1 to S3 can be repeatedly started by a keyboard operation, and when transferring NC data, the processing procedure from S1 is performed again.

As described above, according to the present embodiment, the NC data, the CAM parameters, and the shape N
It is determined from the creation date of the C data whether to update the NC data, and if the update is necessary, the CAM program can be automatically started and the NC data can be updated, so that the operation time (CAM execution time, CAM execution time, It is possible to significantly reduce the NC data registration time) and prevent a processing error caused by erroneously performing processing with old NC data.

Further, by adding the continuous processing information corresponding to the number information of the production instruction information to the NC data at the time of transfer, the number of startup operations of the NC machine tool can be reduced when performing the processing using the NC data.

Further, since the figure numbers constituting the same serial number can be continuously transferred, the transfer operation time can be greatly reduced. And since it is easy to transfer the drawing numbers of the same material work all at once, it is possible to reduce the number of setup operations such as tool change and material change for other material processing and operation Rate can be improved.

[0050]

As is apparent from the above, the present invention significantly reduces the operation time required for the operation related to the update of the NC data, the operation related to the transfer of the NC data, and the start operation of the NC machine tool, as compared with the related art. The operation rate can be improved by reducing the number of setups of the NC machine tool.
