Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a processing information management device in an NC processing machine.

(Conventional technology) Conventionally, processing information such as material data created for NC program data is managed in an office, for example, by an automatic programming device, is printed out when creating an NG tape, and is sent to field workers. It is handed out and used as a work instruction.

In addition, machining information may be set as annotations in the NC program and used for display confirmation on the CRT screen.

(Problem to be solved by the invention) However, the conventional method of using processing information as described above only serves as a work instruction for workers, and it is difficult to organically use this information in EMS. I couldn't.

That is, for example, in a turret punch press, material (material, plate thickness, size) data is used as processing information.

Clamp position data, machining time data, and a list of used molds are shown, but for example, it is not possible to compare the list of used molds with machine parameters, and even if the number of materials is specified as 5, this It was not possible to command the automatic warehouse J from the NC processing machine side.

Under the recent trend of FMS, various processing machines are organically connected for the purpose of producing a small number of different products, so it would be convenient if processing information could be used organically.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a machining information management device that can be used in an NC machining machine and organically utilize machining information.

[Structure of the invention] (Means for solving the problem) As shown in FIG. 1, the NC of the present invention solves the above problem.
The machining information management device 1 in J3 in machining d includes a machining information data file storage unit 35 that is connected to the NC device 3 and stores machining information such as material data created for the NC program data as a data file; The present invention is characterized in that it includes a management control section 57 that makes the file correspond to the NC program data or the actual state of the NC processing machine, and performs a preliminary check of actual processing and data processing for generating an external output signal.

(Function) In the machining information management device 1 in the NC machining machine of the present invention,
The machining information created for the NC program data is stored in the machining information data file storage section 5 as a data file.

The management control unit 7 correlates this data file with the NC program data or the actual state of the NC processing machine, thereby performing a preliminary check of actual processing and data processing for generating external output signals such as delivery commands. I can go and do things.

(Example of 71 colors) Hereinafter, the present invention will be described in detail based on the accompanying drawings.

As shown in FIG. 2, the processing information management device 18 of this example is
Processing information data file storage section 5a and data generation section 7
turret punch press (not shown)
is connected to the NC device 3a.

The NCB device a of the turret punch press is internally equipped with a machine parameter storage section 9a, an NC program data storage section 9, and an input/output section 11 connected thereto. The input/output section 11 is connected to input operation devices such as a keyboard and CRT, and input/output signal lines of the turret punch press, and also communicates with a main computer forming an FMS (not shown), an automatic warehouse, etc. via an appropriate controller. connected via wire.

As shown in FIG. 3 as a display example, the machining information data file storage section 5a stores U It data, clamp position data, machining time data, and used mold data created for the NC program data. It is stored in a readable and writable format as a file. As shown,
These data can be displayed as appropriate on the CRT screen 13 (m), and can be printed out as appropriate.

The data generation section 7a extracts NC program data and processing information from the NC program data storage section 9 and processing information data file storage section 5a, and generates new data.

For example, as shown in FIG. 4, based on the material data, the controller 17 of the automated warehouse 15 sends information to the controllers 1 to 21 of the processing cell (turret punch press) 19 (NC device and other control GI locations). From this, the delivery request signal Q can be output in the form of adding the number of sheets to the material data. As a result, the controller 17 of the automatic AII 15 loads the predetermined material IW onto the pallet 23 in response to this signal Q.
The soup stock can be made into a loader (not shown).

The comparison unit 7b extracts NC program data or machine parameters and machining information data from the NC program data storage unit 9 or machine parameter storage unit 9a and the machining information data file storage unit 5a before starting machining,
By comparing the two, it is possible to check in advance the machining that will be executed in the future.

For example, as shown in FIG. 5, the used mold data and clamp position data owned by the machining information data file 58, and the mold layer i~ and the ramp position on the turret owned by the machine parameter storage section 9a. If they are different, the machining by the NC program is automatically stopped, and the meshage can be displayed on the CR7 screen without prompting the operator to replace the mold or change the clamp position.

In the example not shown in Fig. 5, in the machining information corresponding to the NC program data, the mold x
Although it is specified that x is to be used, the machine parameter, that is, the mold ΔΔΔ is actually set to J3, indicating that the processing conditions are different. Therefore, in such a case, processing can be automatically stopped and a predetermined message can be output.

Note that the turret punch press of this example is not equipped with an automatic die exchange device and an automatic clamp position adjustment device, and actual die exchange and clamp position adjustment are performed manually. Therefore, in this example, we decided to output only the message as described above, but by managing processing information as a data file in this way, it will be possible to use it in automatic mold change equipment and automatic clamp position adjustment equipment in the future. It becomes possible to respond.

Furthermore, the comparison section 7b compares the NC program data and the machining information in advance for all NC programs called by the schedule program before performing scheduled operation, It is possible to check the machining that will be executed from now on and prevent machining errors from occurring.

The data editing section 7C can display mold data and clamp position data on a CRT as shown in FIGS. 6 and 7, and can edit the data as appropriate to match the actual machine.

As described above, in the processing information management device of this example, processing information is stored as a data file, so data can be processed by the data generation section 7a, and data can be processed by the comparison section 7b.
A preliminary check can be performed at , and the data can be edited at the data editing section 7C.

In addition, the processing information stored in the processing information data file storage section 5 can be taken out as appropriate, and can be subjected to various processing such as statistical processing on another computer. In addition, the management control unit 7 can be provided with other appropriate functions such as the pipe embedding control 21I.

The present invention is not limited to the above-mentioned embodiments, but can be implemented in other appropriate modes by making appropriate design changes.

[Effects of the Invention] As described above, according to the processing information tube F of the NC processing machine of the present invention, processing information is stored as a data file in relation to the NC device, so that advance checks of processing can be performed. It is possible to issue instructions for material delivery to the own #J warehouse, and processing information can be used in various ways with the NC device and connected equipment.
