Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work information cost estimating device and a work information output device, and more particularly to a three-dimensional model (3D model) created by a three-dimensional CAD system in sheet metal design of three-dimensional machine design. The present invention is applied to an apparatus that performs post-processes such as sheet metal cost estimation, creation of two-dimensional drawings, and creation of NC manufacturing processing data by giving work information.

[0002]

2. Description of the Related Art Conventional three-dimensional CAD (Compute) using a computer such as a personal computer and a workstation.
r Added Design)
A three-dimensional CAD is used to model a sheet metal part. In the sheet metal design, a two-dimensional drawing is created from the modeled data. The three-sided view, sectional view, and perspective view of the two-dimensional drawing
Although automatically created, the processing information necessary for manufacturing such as welding spots and painting methods is manually drawn in the drawings. For this reason, there are problems such as an increase in the number of man-hours for creating a two-dimensional drawing by the designer, an increase in the design period, and a decrease in work efficiency due to the need for human labor.

In recent years, cost simulations have been performed to reduce the cost of sheet metal parts. As a result of the sheet metal cost estimation simulation, for example, a two-dimensional drawing (three-view drawing) created from the three-dimensional model is output to a printer by printing. Materials required for cost estimation, number of screw holes, number of general holes, sheet metal development dimensions, number of bendings, number of welding points, etc.
The zero item of processing information (parameters) is manually counted with reference to a paper drawing. In the parameter input to a commercially available sheet metal part cost estimation tool operating on a computer or a sheet metal part cost estimation tool developed in-house, the counted parameters are manually input into a commercially available word processor or a dedicated editor, and the cost estimation is performed. Is calculated.

In the manufacture of sheet metal parts, an NC turret punch press (NC) manufactured by an in-house factory or a sheet metal processing manufacturer
T) and NC data for controlling a processing machine such as a bending vendor include two-dimensional outline data (D
XF, IGES, etc.) and paper drawings are manually created and input to the CAM system. Further, even though the three-dimensional data is provided, there is no processing instruction information such as welding and painting, so the NC data of the processing instruction information is manually created and input to the CAM system.

[0005]

However, the conventional three-dimensional mechanical design CAD has the following problems. Since the design / manufacturing process after the modeling of the sheet metal part by the three-dimensional mechanical design CAD cannot be automated using only the shape data of the three-dimensional model, the design man-hour is increased.
There has been a problem that the AT increases, the design quality decreases, and the manufacturing period increases. Further, in the sheet metal cost simulation, there is a problem that a man-hour and a TAT due to a drawing release time, a time for reading welding and painting information from the drawing, a time for inputting the read information to the simulation tool (keyboard input) are increased. .

Further, there is a problem that the accuracy of the simulation result is reduced due to an error in reading information from a drawing, an error in inputting information on a keyboard, and the like. In the cost simulation, if the simulation result exceeds the target cost, the three-dimensional model is modified, and the simulation is repeated until the result falls within the target cost. Therefore, re-input (manual input) of information is necessary,
The man-hour and TAT further increase. In the two-dimensional drawing creation, a processing method related to sheet metal part manufacturing is manually described in a drawing, and a drawing drawing symbol such as spot welding, arc welding, projection welding, stud welding, painting information, masking, etc. is placed at a corresponding position in the drawing. And the display of a label. For this reason, the drawing time becomes enormous, and the probability of occurrence of a description error due to manual operation increases, so that the possibility that the design quality deteriorates increases.

Further, manufacturing data (N
In creating (C data), data input to the CAM system, sheet metal development, NCT data, and bending vendor data can be automated. However, information necessary for processing such as spot welding, arc welding, projection welding, stud welding, coating information, masking information, printing information, chamfering information, and finishing information does not exist in the 3D model. Therefore, information necessary for processing is manually read from a two-dimensional drawing and issued to a manufacturing department (processing maker) as an instruction. Therefore, there is a problem that the manufacturing period increases. In addition, there is a problem that the manufacturing period is increased because welding positioning information (ejection, depression) is manually created. Since welding positioning information (ejection, depression) is also manually created, the welding position may be different from the drawing, and repair or re-creation after manufacturing may be performed in some cases.

The location is searched, and the line containing the location is referenced. As the shape information, a code including “D1_004” is generated from the tool code 316. In this code, the height is “3.0” mm from the column of height 315, and the correction table is “offset_allow (d)” from the column of correction table 317.

Cost estimation of sheet metal parts, which has been performed only in the factory department or the purchasing department, can now be performed at the machine design stage in the upstream process. Therefore, since the cost can be known before the production, the cost can be evaluated whether or not the production can be performed within the target cost. If the target value is exceeded, the model can be corrected immediately and the target cost can be achieved. As a result, it is possible to reduce the number of trial productions by VE and the number of prototype design man-hours conventionally performed after the completion of the production.

Further, since parameters necessary for cost estimation can be generated from work information on the 3D model, a cost estimation simulator is activated in conjunction with the three-dimensional machine design system. As a result, the parameter input time is also reduced, so that the cost estimation time is reduced. Summing up the cost estimation results of all the sheet metal parts used in one apparatus makes it possible to obtain the total cost of the sheet metal parts used in the apparatus. Further, the purchasing department also eliminates the operation work of the cost estimation simulator by employing the simulation result performed on the design side in the cost estimation simulation that was performed in the price negotiation with the processing maker, thereby reducing the man-hour of the purchasing department.
