Description

Measurement and Management System for Mold Manufacture Machine {Measurement and Management System for Mold Manufacture Machine}

The present invention relates to a mold manufacturing work measurement management system, and more particularly, by listing the processing conditions, it is possible to easily determine and modify the appropriate mounting of the tool size, and the weight to the theoretical processing time It relates to a mold manufacturing process measurement management system that can predict the actual processing time required by placing it.

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 processed in many parts using a machining center. To process 3D shape, NCDATA is created using a 3D CAM program and sent to the machining center to process it with the NCDATA code command. This is going on. NCDATA created in this process is created by high-paid technicians in every process, including input, deletion, and correction, and the quality of data also varies greatly, and depending on the quality, it affects productivity and efficiency a lot.

1 is a flow chart of generating NCDATA according to the prior art.

Conventionally, the process from the 3D model to the creation of the final CAM DATA (NC Code) for processing was generally carried out manually by an experienced operator while going through the same process as shown in FIG. 1.

To explain each of the processes described in Fig. 1, first, model import is a process of importing modeling data for 3D processing from DB, and area designation is a process of specifying the size of the processed material by block, and tool setting is the original material. It is a process of setting the tool for cutting by attaching it to the machine with a stronger material, and the cutting condition input is the process of inputting conditional information about the tool rotation and progress speed for processing, and the safety height input is the machine It is the process of inputting the range in which collision does not occur during movement, the tolerance input is the process of inputting the surface roughness of the product shape, the boundary input is the process of deciding which part of the mold processing to be processed, and the tool pitch input This is the process of entering the tool's one-time infeed by marking it as X, Y or Z, and the calculation is the last operation performed when all machining conditions are set, and editing is an unnecessary air cut part after the tool path is created. The tool holder application and verification is a process of verifying by applying a holder that can attach and detach a cutting tool called an end mill or cutter, and the tool overcut verification is a process of overcutting when a tool path is created. It is a process of checking whether it occurs or not, and NCDATA output means a process of outputting data consisting of G code to run the CNC machine.

In the existing process, an expert is needed in the 3rd step of the tool setting part, the tolerance input in the 6th to 8th steps, the boundary input and the tool pitch input part, and the 10th step editing part. In addition, there are many tasks (mouse work) that are repeated after this editing process.

As described above, in the existing method, if the process is repeated, the operator must continue to reside on the computer, rework due to typos is required, product defects due to typos are high, and computer computation takes a long time. There was a problem that work efficiency was degraded because work was possible only on a computer.

In addition, there is a problem in that there is a difference in the time to generate the NC code, the time to process using the NC code, and the stability and quality of work, depending on the career, skill, ability, and will of the person in charge of the job.

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

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

On the other hand, in addition to the above-described problems, in a general automatic machine tool (machining center), a fatal problem occurs in the workpiece due to collision with the workpiece or holder during tool movement during the mold processing process. By creating (Tool Path), it is necessary to determine that a tool must enter the address in the program so that it is not a problem.In the past, this point was printed out as a document and visually checked with a highlighter, and the inconvenience and inconvenience of installing the actual tool. There was a ship.

If the tool holder (ABOR) is incorrectly selected, a fatal problem occurs on the workpiece due to the collision of the tool holder, an overload is caused in the processing machine, and subsequent linkage work in the automated work is impossible.

For this reason, we are still in a situation where we have no choice but to rely on the human resources of highly skilled workers, and moreover, the problem of not accurately predicting the time required for machining occurs frequently, and it is necessary to predict the time until the actual workpiece processing operation enters and ends. it's difficult. For example, there are operations that take about 4 to 5 days, which is the time required for processing.

Therefore, for such reasons, it is difficult to ascertain the delivery date of the work piece to the customer. For example, if the delivery date is longer than expected, it is a violation of the promise, which may eventually lose the trust relationship with the customer. .

In other words, the problem of the existing method is that the machining time of the tool path (tool path) is different from the actual required time, so the machining work plan of the next workpiece is unclear because the actual time required is different, and the operator must always wait for the optimal operation rate. The problem and the time required for each machining center are different, and as the number of tools increases, more user errors are generated, and as the number of processes increases, more user errors are generated.

On the other hand, in the following, the patent documents of the prior art documents related to the automation solution for machine processing are disclosed.

Patent Document 001: Patent Publication No. 10-2006-0075911 Patent Document 002: Registered Patent No. 10-1245723 Patent Document 003: Public Utility Model Office 2001-0001938

The present invention for solving the above-described problems can arrange and list the information of the entire tool path through the development of a program (tentative name'Powermill Friends'), and set the normal category and select items that are not. It informs in a way that induces re-review through automatic coloring with a program, and makes it possible to easily judge and correct the proper installation of the tool size by listing the machining conditions, and weights (AAC, T) to the theoretical machining time. , RB, RC) to provide a mold manufacturing work measurement management system that can predict the actual processing time required.

There is one feature of the measurement management system for the mold manufacturing process.

If the result value of the target time required (S6) according to the time required setting and synchronization start (S5) is not matched or not satisfied compared to the result value of the actual time required calculation (S8), the combination operation setting of the processing variable elements (S7) )(S7')(S7") is performed several times so that the result value of the target time required (S6) matches or satisfies the result value of the actual time required calculation (S8). There is this.

The above required time varies depending on the automatic tool change, AAC change, B-axis and C-axis conversion, and the required time for each equipment varies depending on whether the corner is accelerated or decelerated during processing, and AAC / T / RB / RC Is a feature of the mold manufacturing process measurement management system, which is a variable for calculating the actual time required based on the machining time.

According to the present invention as described above, since the actual processing time required for processing of the workpiece can be predicted, the workpiece can be delivered in a timely manner to the customer according to the delivery time of the processed workpiece, so that the transaction with the customer There is an effect that can increase trust.

In addition, according to the present invention, there is an effect of preventing a defect in a processed work by preventing an error in selection of a tool holder in a process of machining a work.

In addition, the drawings attached to the present invention are shown for the purpose of simply grasping the components of the present invention, and the specific position or arrangement of the components does not have a significant meaning of the invention.

Moreover, the accompanying drawings illustrate preferred embodiments of the present invention, and serve to further understand the technical idea of the present invention together with the detailed description of the invention to be described later, so the present invention is limited to the matters described in such drawings. It should not be interpreted, and the size or shape of the configurations described in the drawings is merely published as a method to aid understanding of the description of the present invention, so the configurations of the present invention should be interpreted as not limited to the drawings.

The present invention provides a mold manufacturing work measurement management system capable of flexibly responding to errors or defects that may be caused in the manufacturing process of a tool path and reducing defects in tool path manufacturing and shortening inspection time through immediate correction. It is based on wanting to provide. The tool path refers to the motion trajectory of the center of the tool for machining into a desired part shape.

As shown in Figure 2, the mold manufacturing work measurement management system according to the present invention includes a cam module 10, a theoretical processing calculation module 11, and a combination operation unit 12 of processing variable elements, and a numerical control manager 13 It can be composed of.

The cam module 10 is a program system capable of calculating NCDATA for 3D shape processing and may model a 3D shape.

The theoretical processing calculation module 11 can start the measurement of the time required for the workpiece to be processed and synchronization of the project.

The combination operation unit 12 of the machining variable elements may operate and set a numerical value together with a combination of the variable elements for the workpiece to be processed.

On the other hand, the control manager 13 is a program tool for setting and controlling combinations and numerical values of the processing elements.

When the cam drive (S1) in the cam module 10 is performed, following the execution of the work file scheduled to be processed (S2), following the display (S3) of the workpiece to be machined and the project feature, the theoretical machining calculation module 11 According to the operation of the theoretical machining calculation module (S4), the time required for theoretical machining of the workpiece to be machined and the project synchronization (S5) starts.

Thereafter, after the operation setting is made in the combination operation unit 12 of the machining variable elements, when the result of the target actual time required (S6) is satisfied, the actual time required is calculated (S8) and then the workpiece is processed (S9). I can.

Hereinafter, the operation process of the mold manufacturing work measurement management system according to the present invention will be described.

In the cam module 10, the actual required time can be determined by converting the difference between the actual machining time and the difference between the machining time of the tool path (tool path).

For example, as shown in Fig. 3, it is assumed that the theoretical machining time in the cam module 10 is 15 hours as a tool path (unit mm) x Feed (cutting speed). In this case, as shown in Fig. 3, there is an advantage of reducing the machining operation of 9 hours as a deviation from the machining time per day.

Due to the extreme variation in processing time and unpredictability of the unmanned processing time, a delivery delay occurs. The variation in processing time and required time occurs as follows.

The operation process of the mold manufacturing work measurement management system of the present invention may be described in a manner referring to FIGS. 2 and 14 as basic drawings, and referring to FIGS. 3 to 13. In the operation process of the system to be described later, even if Figs. 2 and 14 are not mentioned, reference will be made to these drawings to aid understanding of the present invention.

Cam drive (S1) in the cam module 10 is performed on the background screen of the monitor as shown in FIG. 4, and the drive screen is activated.

Thereafter, according to the activation of the cam drive (S1), the work file execution (S2) scheduled to be processed is displayed on the screen as shown in FIG.

Accordingly, a display (S3) of the workpiece to be machined as shown in FIG. 6 and the project feature as shown in FIG. 7 is made.

Thereafter, as shown in FIG. 8, the theoretical processing calculation module 11 (tentative name: Powermill friends) is driven (S4) according to a click of a new tab on the screen.

Thereafter, the required time setting and project synchronization (S5) as shown in FIGS. 9 to 11 are started through the theoretical processing calculation module 11.

That is, as shown in FIG. 11, the required time for each device is set. By setting the time required for each equipment only once, it is still valid. After setting the time required, click Synchronize Project.

Thereafter, in the combination operation unit 12 of the machining variable elements, the machining increase/decrease rate, machine origin movement, AAC exchange, tool change, B-axis rotation, C-axis rotation and The combination and time of the same processing variable elements can be set. That is, the process of combination operation setting (S7) of the processing variable elements can be performed.

Of course, before the process of the combination operation setting (S7) of the processing variable elements is performed, after setting the required time and starting synchronization (S5), the result of calculating the actual time required (S8) is equal to the result of the target actual time required (S6). If matched, the combination operation setting (S7) of the processing variable elements may be performed only once, without the need to be performed, the required time setting and synchronization start (S5).

However, if the result value of the actual time required calculation (S8) does not match the result value of the target actual time required (S6), the actual time required is calculated in a manner in which the combination operation setting (S7) of the processing variable elements is performed several times ( The result of S8) may match the result of the target actual time required (S6).

As such, the result of the actual time required calculation (S8) is displayed on the screen by calculating the actual processing time as shown in FIGS. 12 to 13. That is, the theoretical processing time 4 hours and the actual processing time 6 hours 24 minutes are calculated results, for example, are calculated values when a specific workpiece is processed.

In other words, in this case, when the actual time required is not a satisfactory result compared to the target actual time required, the operation setting (S7) is made in the combination operation unit 12 of the processing variable elements.

Thereafter, after the operation setting (S7) in the combination control unit 12, the actual time required is calculated (S8) according to the start of synchronization, and if the actual time required corresponds to the result of the target actual time The process of the present invention can be performed and terminated (S9) machining of the workpiece.

As described above, the present invention aims to operate the effective equipment by calculating the total processing time by calculating the theoretical processing time and the additionally occurring time in a 5-sided processing machine and adding the actual processing time.

Moreover, it is possible to prevent defects of the workpiece through more accurate prediction of working time and tool path check.

In the process of listing the information of the entire tool path, the time required for each process can be entered and calculated, and the actual machining time can be accurately predicted by weighting the theoretical machining time (accuracy of 90% of the actual time required). And the delivery date can be predicted more accurately), and it also reduces defects that may occur during toolpath manufacturing and shortens inspection time.

The numerical control manager 13 in the combination operation unit 12 of machining variable elements controls, for example, an array of machining variable elements that will act as variables for machining a workpiece, and a combination and numerical value of these elements. Machining components are, for example, TOOLPATH (= path through which the tool passes), T.NO (= ATC (automatic tool changer) slot number installed on the machine), TOOL (= cutting tool (20B -> 20 pie ball end mill) ), HOLDER( = Tool holder that connects the tool to the machine), Overhang( = Length of the pure cutting tool), HL( = HOLDER + Overhang value as the length from the end of the machine to the end of the tool.), Check the blade length (= Tool If the is longer than 5 times the diameter, the item that confirms that there is room for a problem in machining by displaying'too long' on a red background, Overhang (=> Tool diameter * 5, expressed as'too long'), Strategy( = Toolpath strategy, the way the tool passes (RASTER, contour lines (= CONSTANT Z), etc.), Thick (= machining allowance, allowance in the dimensions of the finished product by anticipating the part that will fall off in the process of processing the product) A.Thick (= axial processing margin, giving a margin to the dimensions of the finished product in the direction of the tool's main axis, like thick), Tol (= Tolerance, precision, the point of the path the tool passes by Decide whether to shoot), Spindle (= rotation (speed), speed of turning the cutting tool), Feed (= cutting tool movement speed per minute), machining time (= time is inferred by reflecting the feed in the toolpath length) , Required time (= The machining start time varies depending on the automatic tool change, AAC change, B-axis and C-axis conversion, and the time required for each machine varies depending on whether the corner is accelerated or decelerated during machining), (AAC / T / RB / RC = variable for calculating actual time required based on machining time), WP (= coordinate system, reference axis view for 3-axis/5-axis machining).

Meanwhile, in the present invention, the machining process generally means a machining method (e.g., roughing, medium cutting, finishing, residual cutting, drilling, boring), and the tool path refers to the tool path that the tool proceeds to process. , FEED means the feed rate in mm per minute that the machine moves while processing, and the machine acceleration/deceleration time is the time at which acceleration and deceleration occur at the start and end points when each axis (X, Y, Z, W) of the machine moves. Meaning, head replacement time means the time to replace the machine head for each process due to different head sizes for each process, and the home position return time is the time to move to the original position of the machine at the beginning and the end per process or to change the tool. It means the time to move to the position or the position to change the head. For example, the 5-sided machine can be presented as an X origin distance of 5200mm, Y origin distance of 3200mm, Z origin distance of 800mm, and W origin distance of 1200mm.

Tool change time means that the tool needs to be replaced for each process due to the difference in tool size for each process, and the head tilting time means the machine motion for machining, that is, the time that the head B axis and C axis rotate, positioning time ( Rapid traverse) means the time to reach the position of the workpiece for the machine to process, and the tool setting time can mean the time to attach the tool to the machine by checking the tool length and tool diameter.

On the other hand, as an explanation of the existing cam terminology, toolpath-The tool path that the tool proceeds to process is called the tool path, and the tool bar-A picture displayed as a group by easily displaying various commands as icons, importing models-3D processing Modeling data, area designation-block-part that designates the size of the material to be processed, tool setting-tool-it is made of a stronger material than the original material and can be attached to the machine for cutting, cutting conditions-for processing Refers to tool rotation and speed, safety height-The act of escape to the extent that collision does not occur when the machine is moving, tolerance-refers to the surface roughness of the product shape, boundary-refers to the area that determines which part of the mold processing is to be processed , Tool pitch-The amount of infeed of the tool is expressed in X and Y or Z, Calculation-The last calculation is performed when all machining conditions are specified.Edit-After the toolpath is created, the unnecessary air cut part or Changed to an optimized path, Tool holder-Refers to a holder that can attach and detach cutting tools such as end mills or cutters, Tool overcutting check-Checks whether overcutting occurs when a tool path is created, NCDATA-CNC MACHINE It refers to the data consisting of G code to operate.

In this invention, the actual processing required time is checked, the actual machine-specific tasks are arranged on the status board, manned and unmanned tasks are arranged to systemize the scheduling capability of the processing team leader, and the relevant departments can also check the device operation status and plans. It was conceived, and in particular, it is effective in achieving the optimum operation rate, removing the uncertainty dependent on the sense of the practitioner, enabling smart manpower arrangement through the optimal manned/unmanned processing arrangement, the difference in processing time (acceleration/deceleration) according to the characteristics of each equipment It can be expected to be useful in responding to estimates for calculating machining time and enabling scheduling in consideration of deviations by equipment.
