    The author makes use of his experience in developing the DUCT CADCAM system at the University of Cambridge and as partner in the firm of Weber CAM GmbH, which programs for the pattern- and mould-making shop Firma August Weber Modellbau in Hildesheim, Germany. He discusses why CADCAM is so little used in the mechanical engineering industry and why designers use CAD systems with little understanding... View full abstract»

    Owing to the complexity of certain tasks, in particular those within a hazardous environment, there is a perceived need for robotic systems to have two-armed flexibility. The practical realisation of a teleoperated two-armed manipulator system raises a number of problems regarding operation and control. Of particular note is the problem of collision avoidance between the arms in real-time. A revie... View full abstract»

  • A framework for design and development of real-time IKBS applications

    Publication Year: 1991, Page(s):241 - 253

    A framework for the design and development of real-time and software fault-tolerant intelligent knowledge-based system (IKBS) is described. It uses an extended notation of structured analysis/structured design (SA/SD) to identify and analyse the requirements, and to arrive at a set of data and control transformations. This set forms the background to identify and describe a set of objects, in the ... View full abstract»

  • Design of an expert system for generating optimal assembly sequences

    Publication Year: 1991, Page(s):255 - 259

    Basically, an assembly process is a sequence of positioning and fixing in position between the parts of the system to be assembled. However, finding this sequence automatically remains a very complex procedure because of the combinational aspect of the problem. The conventional programming methods of generating the ordered sequence cannot satisfy the modern factory requirements. The new approach, ... View full abstract»

  • Generative feature-based design-by-constraints as a means of integration within the manufacturing industry

    Publication Year: 1991, Page(s):261 - 267
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (558 KB)

    The article examines the development of computer aids within manufacturing industry and proposes an alternative approach to the way we design and the designer's role within manufacturing. A feature-based generative design-by-constraints approach is applied, which requires the designer to specify solutions in terms of manufacturing data, which is captured by means of an interactive simulation of ma...
