Problems solved by technology

However, this smoothing process is complex and time-consuming
In addition, since the car body has a wide area, correcting the 3D measurement mold data for all the surfaces of the car body would add too much load to the computer and would be time-consuming.

Embodiment Construction

[0057] Refer to the following Figure 1-10 A method for determining grid data according to an embodiment of the present invention is described.

[0058] First, the following reference figure 1 The previous process performed before the method of determining grid data according to the present embodiment will be described.

[0059] exist figure 1 In step S1 shown in , a molded article to be obtained is designed, and data of a molded article model is generated.

[0060] In step S2, the data of the die model is generated on the CAD system based on the data of the molded product model.

[0061] In step S3, NC (numerical control) data for controlling an NC (numerical control) machine tool is generated from the mold model data.

[0062] In step S4, a mold as a test mold is produced by an NC machine tool based on the NC data.

[0063] In step S5, the molded article serving as the test article is pressed using the produced test mold.

[0064] In step S6, the test article and the f...

Abstract

A die fabricated based on reference model data is corrected, and the corrected die is measured with a measuring instrument to provide three-dimensional measured die data. Noise areas in the three-dimensional measured die data are identified and removed using a computer. The three-dimensional measured die data and the model data are placed in proximity to each other, and a stacking and deforming process is performed in order to project a model surface represented by the model data onto a measured data surface represented by the three-dimensional measured die data. The stacking and deforming process is performed only within a range of the model surface that corresponds to an area in which the die is corrected. Portions of the three-dimensional measured die data from which noise areas have been removed are complemented by the model data.

Description

technical field [0001] The present invention relates to a method of correcting model data by correcting a mold or actual model that has been produced based on model data used as a reference, measuring the corrected mold or actual model with a measuring instrument so as to obtain three-dimensional measurement data, and thereafter A first surface represented by the three-dimensional measurement data is brought adjacent to a second surface represented by the model data for correcting the model data using a computer for comparison between the first surface and the second surface. The present invention also relates to a method of determining mesh data by measuring the surface shape of a workpiece with a measuring instrument, thereby obtaining mesh data composed of a plurality of network elements, and then using a computer to identify noise points within the mesh data area to determine the grid data. Background technique [0002] Heretofore, a stamper has generally been produced ...
