REMODELING OF COMPLEX SURFACE PATCHES BY USING THE METHOD OF CHARACTERISTIC FEATURES – THE SKI SHOE HEEL LIP EXAMPLE

Abstract

Reverse engineering is an important part of the industry because it enables a more profound understanding of product properties such as shape, geometry, material, and functionality. If there is a requirement to acquire information about an object shape or geometry, then two activities are generally conducted, scanning and remodeling. Scanning presumes using a 3D scanning device to obtain product geometrical data, while remodeling produces a part geometrical model. Various methods are used for obtaining a geometrically accurate and topologically correct geometrical model of the scanned part, and in this paper, a novel method based on Characteristic Product Features (CPFs) is presented. CPFs is focused on defining product Features of Interest (FsOI) and using them to fulfill reengineering requirements of a specific industrial product. FsOI represent particular sections of the part that are geometrically defined and can be used for further processing, such as creating specific 3D models. The CPFs method application was demonstrated by making a ski shoe heel lip 3D geometrical and physical model using 3D printing. The resulting models completely satisfied initial geometrical, functional, and mechanical requirements.
