Abstract

The key development in this project is the elaboration of an internal representation of parts which allows an automatic achievement of all the advantages of group technology and classification integrated into the different CAD/CAM systems used by the partners in the project. By automating group technology, human interpretation of engineering drawings during the coding process, is excluded. The automatic retrieval of existing similar parts, subassemblies and assemblies will be possible, moreover also the retrieval of appropriate manufacturing information sequences will be in the bounds of possibility. Until now the consortium has worked on two prototype software packages. One working group developed a package for the automatic creation of the computer internal representation of simple parts whereas the other group concentrated itself on the automatic retrieval of assemblies and family parts from a data model, that is based on family information. The two packages were only tested in a limited degree, although those results are satisfactory it is still too soon to draw conclusions.
