Abstract
Rapid product development is today widely developed in design and industrialization stages of the development of a new product. Rapid tooling and manufacturing technologies allow producing rapidly very complicated parts, from a numerical model. The problem is to be able to obtain a rapid validation of the technological processes in order to verify the conformity of the part compared to the numerical reference model. So, the goal is to control efficiently parts that have most often a very complex geometry. Based on our experience on laser scanning, this paper proposes a solution in order to improve the efficiency of the geometric and dimensional control process. The proposed solution is an application and adaptation of the visibility theory to the automatic determination of the scanning strategies for the digitization of 3D complex parts, using a plane laser sensor. This has been applied in different industrial fields like foundry, plastic injection, etc…
