What is Design of the database for CAD based on group technology about?

An important part of integrated CAD/CAPP/CAM is represented by the database in which all the information and data relevant for the design, planning and manufacturing of a component are available to the designer. The database must thus include relevant data about the geometrical primitives, materials, surfaces, tolerances, etc. This paper reports on the design of a database to be used in CAD/CAPP/CAM with particular reference to GT principles. The data required in the CAD process are strongly structured, so that their computer representation actually yields a structural model of the component. The elements which form the component model are parameterized shape primitives generating the matrix of the primitives for forming rotational and non-rotational components. The organization of their data and the communication between the designer and the database are discussed in detail. In this context a solution is proposed which enables the designer not only to draft a component by means of a computer, but, at the same time, to classify the component into a part family using a pattern recognition method for computer-aided GT classification.
