Computer-integrated manufacturing (CIM) and revers e engineering (re) have changed drastically the concept of product re-design, pla nning and manufacture of components. However, the main problems currently facing the developers of reverse engineering system, is the time consuming digitis ation of 3D data and the conversion of large amounts of data into a concise and manageable format and linking it to a CAD/CAM system. Automated 3-D profile gen eration, measurements and inspection of manufactured component represents one of the important functions in reverse engineering and in the improvements in produ ct quality in rapid product developments. The paper presents a novel methodology for the development of a reverse enginee ring technique for use in the rapid product development in a CIM environment . The system developed provides integration, data capture and manipulation, dat a transfer between a CAD, CAM, Computer-aided inspection (CAI) and a 3-D profi le scanning system. An efficient scanning strategy has been developed for scann ing and surfaces data acquisition. The products were scanned using a laser scann ing system with a dedicated scan control card and the associated software packag es. A versatile rig was developed for the ease of data gathering of the profile scanning process. The surface data collected was then used to build a mathematic al surface model, which was then used to develop a virtual 3-D model of the pro duct. The resulting surface model provides the geometrical input to the subseque nt machining operation using either a CNC system or other manufacturing operatio n e.g. dies casting/mould casting etc. The prototypes developed were inspected u sing a state-of-the art CNC-CMM that was integrated to the CAD/CAM system. Si nce the scanning/digitised data captured by laser scanning probes requires no ma nual editing, significant time saving over most non-contact probe systems was a chieved. Since the creation of an accurate CAD model of a redesign

A turbulent re-engineering of higher education and higher education institutions is underway in many countries across the world to achieve a more direct and pro-active engagement with society in general than ever before. This paper presents the authors’ suggestions on the concepts and philosophy of quality-assured industry-oriented higher education based on the close cooperation between DIT and HIT, particularly on the recently completed EU Asia-Link EMERSION project in relation to software education, as a constructive contribution to the process of re-engineering higher education.

A concurrent product development example is used in this paper to introduce a roadmap for integrated and concurrent product development. The roadmap covers the following steps: (1)enterprise problem specifying; (2)information integration modeling; (3)integrated products development team modeling; (4)product development process modeling; and (5) integrated information-process-organization modeling. They have been successfully applied in the major pilot project of "Concurrent engineering" of the 863 Programme of China.
