Description

{Vefification and Management System for Tool machine of Mold Manufacture}

The present invention relates to a system for verifying and managing the work of a mold making tool, and more particularly, a mold making tool capable of preventing an over travel problem, such as an excessive range of machining of a work occurring in the mold manufacturing process. It is about the verification and management system of the peacock.

In general, in the field related to mold production, modeling made through 3D design is already widely used for processing, assembly, and management.

In order to manufacture the mold, the material of the mold is cut in many parts using a machining center. To process a 3D shape, a 3D modeling file is created using 3D CAM program, NCDATA is created and transmitted to the machining center to be processed by NCDATA code command. This progresses. The NCDATA created in this process is a high-wage engineer who directly inputs, deletes, and modifies all processes, and the quality of data also varies greatly and affects productivity and efficiency depending on the quality.

1 is a flowchart for generating NCDATA according to the prior art.

In the past, it has been common for a skilled worker to manually perform a process from such a 3D model to the creation of the final CAM DATA (NC Code) for processing, as shown in FIG. 1.

To describe each process described in FIG. 1, first, model import is a process of importing modeling data for 3D processing from a DB, area designation is a process of designating a block size of the material to be processed, and tool setting is the original material. It is a process of setting a tool for cutting by attaching it to a machine made of a stronger material, inputting cutting conditions is a process of entering condition information about the tool rotation and progress speed for processing, and entering a safety height This is the process of entering the range where collision does not occur when moving, the tolerance input is the process of inputting the surface roughness of the product shape, the boundary input is the process of determining the part to be processed in the part, and the tool pitch input is This is the process of inputting the infeed amount of a tool in X, Y, or Z, and calculation is the last calculation operation performed when all machining conditions are determined. Editing is an unnecessary part of the air cut after the tool path is created. Or, it is a process of changing to an optimized path, and applying and verifying the tool holder is a process of verifying by applying a holder that can attach and detach a cutting tool such as an end mill or a cutter. It is a process of checking whether it occurs or not, and the output of NCDATA means the process of outputting data composed of G codes for operating CNC (computer numerical control) MACHINE.

In the existing process, experts are needed in the tool setting part, which is the 3rd step, the tolerance input in the 6th to 8th steps, the boundary input and the tool pitch input part, and the 10th edit part. In addition, many tasks (mouse tasks) are repeated after the editing process.

As described above, in the existing method, when the process is repeated, the worker must constantly reside on the computer, rework due to typos is required, the probability of product defects due to typos is high, and computer computation time is long and one computer There was a problem in that work efficiency can be reduced because only a computer can work.

In addition, there was a problem that the time to NC code generation, the time to process using NC code, and the stability and quality of work occur depending on the career, skill, ability, and will of the corresponding person in charge.

On the other hand, since the progress of each process is entirely dependent on the skill and know-how of the worker, there is a problem that a lot of know-how related to the work is lost when the person in charge is absent or leaves the company.

This problem described above could be solved by the registered patent No. 10-1739354 filed and registered by the applicant of the present invention.

In the past, the history of each tool was managed depending on the memory of the field technicians, thus processing the workpiece. Inaccurate problems such as over travel out of range are emerging.

That is, in the existing machining process, tool information such as tool length, tool diameter and tool number in the cam module is manually entered, and then the tool information in the machining center device (tentative name: MAGAZINE Tool Pot). At this time, an error due to visual inspection occurs, and after writing in a note (defects due to erroneous writing), the tool holder verification, cutting check, and machine motion are manually verified. Excessive time is being used to select the tools required for machining, and after setting the tool, visual inspection of the workpiece center's coordinate system, handwriting in the information of the machining center's workpiece coordinate system (defects due to erroneous writing), NCDATA output, and then machining When testing and machining are performed, there is a serious situation in which machining of a workpiece is stopped due to phenomena such as over travel outside the machining range of the workpiece.

As described above, the existing problems include incorrect reading of the tool holder and tool name during the process of mounting and processing the tool on the actual equipment for machining, or repeated defects in the process setting inspection process of tool setting and machining test, or reviewing after the start of machining. Automated machining was difficult due to frequent mistakes and defects in machining due to difficulties such as problems of the workpiece or over travel (out of the machining range).

On the other hand, hereinafter, patent documents of prior art documents related to an automated solution for machining are disclosed.
