Identification of Ruled Surfaces in a Model Reconstruction Step

Abstract

Reverse engineering is integrated in today’s industry on physical models, as a solution to remove imperfections, enhance functionalities, generate a symmetrical part, or simply duplication. Weaknesses and limitations of the conventional model reconstruction methodologies, whether manual or automated, arouse when it comes to recognition and reconstruction of an extensive, yet very important type of surfaces: ruled surfaces. Our focus in this work is on the link between the numerical model resulting from digitization, and the final CAD (Computer Aided Design) model. We will extend our work by giving a perspective on the manufacturability of ruled surfaces. Our objective is to automate ruled surfaces recognition during the model reconstruction step, and enrich them with geometrical information that will simplify their manufacturability.
