3D PARAMETRIC MODELLING DEDICATED TO GROUP TECHNOLOGY

The parametric geometric modelling, fundamental instrument of CAD, has laid the groundwork for important changes in this area. Thus, the parametric modelling has contributed to optimal design of the products and has led to increase of the design efficiency process by reducing design costs by shortening design time. Far from being exhausted of the parametric modelling potential, a possible application is linked to the group technology. In this context is framed this proposed article. In the first part of the article is presented the general framework of the issues approached. Further, are given the main concepts and principles underlying parametric modelling dedicated to the group technology. The justification and validation of the enunciated concepts and principles, is made through a case study. The end of the article is dedicated to some conclusions and observations of the author
