Experimental verification of a generation method of pseudo-surface models applying for mechanical design

Abstract

In the field of product development, shortening of process time is desired and simulation such as CAE is essential. However, the product shape modeled by CAE is an ideal shape without irregularities and is different from actual products. Therefore, generation method of surface models with irregularities (skin model shapes) has been developed using DTCWT (dual-tree complex wavelet transform). Skin model shapes are models represented by points, polygons, or functions, and often used in tolerance analysis. In this study, we compare skin model shapes generated on a computer with the surface of the actual processed material and verify the validity of the method.
