Paper Abstract

This paper introduces the first results of a research work carried out on the automation of digitizing process of complex part using a precision 3D laser senor. Indeed, most of the operations are generally still manual to perform digitization. In fact, redundancies, lacks or forgettings in point acquisition are possible. Moreover, digitalization time of a part, i.e. immobilization of the machine, is thus not optimized overall. After introducing the context in which evolves the reverse engineering, we quickly present non-contact sensors and machines usable to digitalize a part. Considered environment of digitization is also modeled, but in a general way in order to preserve an upgrading capability to the system. Machine and sensor actually used are then presented and their integration exposed. Current process of digitization is then detailed, after what a critical analysis from the considered point of view is carried out and some solutions are suggested. The paper concludes on the laid down prospects and the next projected developments.
