Brief

    The objective of the workshop was to present recent developments in the area of product design and development, and to relate these developments to the applications oriented needs of industrial users. The workshop consisted of a series of specialist presentations from a team of lecturers from Belgium, Germany, Ireland, Italy, Syria and the United kingdom. A number of short papers were made by colleagues from Jordan, Syria, Czechoslovakia and France.

    Today’s business world requires product manufacturers to design high quality products which meet demanding customer requirements, can be manufactured economically and can be brought to market very quickly. As well as the “traditional” requirements to design for quality, price and function, today’s designers must also take cognizance of the design cycle: time, ease of manufacture and increasingly design for environmentally. Being production. Furthermore, many of today’s products and indeed components are designed by design teams, which are frequently geographically dispersed and involved members from more than one enterprise. Teams formed by designers from specialist components or module suppliers and their customers (the product final assemblers), are reasonably common in the automobile, machine tools and aerospace industrial sector. Data exchange between team members is important and hence the interest in product data modeling and CAD data exchange standards. The workshop is divided into six parts. Part one looked at developments in manufacturing, in particular the emergence of the Extended Enterprise. The Extended Enterprise, with it’s emphasis on co-operation along the value chain between sub-suppliers, suppliers, final

    assemblers and customers, all mediated by a powerful telecomputing infrastructure, provides the context for today’s product developers.

    Concurrent Engineering, the need to reduce time to market for new products by a multi-function team based approach to product design, is the subject of part two professor Jacques peters, drawing on his long experience in Louvin, discusses the various approaches to Concurrent Engineering, including organizational and technological issues (e.g. rapid prototyping), and illustrates his points with examples from industrial practice. In part three we turn to the subject of CAD. Dr. McMahon’s theme is that CAD is primarily concerned with the creation manipulation and application of models of design within the design process. He concentrates on modeling the geometric from of the product and includes detailed material on information models and techniques for storing, manipulating and displaying models, all illustrated by examples. He concludes his section with a discussion on feature based design and a brief overview of widely used commercial CAD software. Given the co-operation between the various actors on the supply chain, and indeed the requirement for co-operation between designers and manufacturers located at different sites, it is not surprising that data exchange systems and standards are important. Part four addresses this important topic and includes material on emerging standards (Step for example) and de

     (DXF/AUTOCAD). facto standards

    In part five professor Hans Grabowski of Karlsruhe considers the issues of CAD/CAM integration. He position CAD (Computer Aided Engineering) in product design process and presents a detailed treatment of computer based process planning and the part programming. Finally in part six professor Claudio Boer and his colleagues consider the issue of shop floor integration. After an initial presentation of the concept of integration, they look in detail at the part programming of robots and NC machines, including metal cutting and metal forming machines. They consider the integration of process planning and NC programming and describe the use of simulators to aid the off-line programming activity. They conclude their presentation with an overview of more recent developments including the emergence of software to support the virtual manufacturing environment
