    Enhancing digital design data availability in the aerospace industry
    (Cranfield University, 2009-03-31) Shehab, Essam; Bouin-Portet, M.; Hole, R.; Fowler, C.; Rajkumar Roy; Essam Shehab
    This paper presents the development of a framework to enhance the current utilisation of digital design data within the aerospace engineering discipline. The quality and timeliness of product design and development decisions depends on the data availability. Therefore, there is a need for enhancing the digital data availability in order to make better decisions in a shorter time, reducing the product lead time. This research project, which conduced in collaboration between Airbus in the UK and Cranfield University, has identified opportunities to exploit the access and sharing of digital data, specifically within the weight engineers and the stress population through the use of Digital Mock-Up colouring and lightweight visualization.

    Investigating innovation practices in design: creative problem solving and knowledge management
    (Cranfield University, 2009-03-31) Baxter, David; El Enany, N.; Varia, K.; Ferris, I.; Shipway, B.; Rajkumar Roy; Essam Shehab
    This paper describes a case study investigating two key aspects of innovation practice in an engineering company: creative problem solving (CPS) and knowledge management (KM). CPS methods offer benefit to organisations in developing novel solutions and improving operations. This research identified the key factors in applying CPS methods from the literature, and compared the creative practices of one engineering organisation with three creative organisations. KM practices can support the sharing and reuse of innovative practices and creative outcomes. A central conflict in adopting KM is codification vs. personalisation. This issue is discussed with reference to a KM framework proposal.

    Reconfigurable micro-mould for the manufacture of truly 3D polymer microfluidic devices
    (Cranfield University, 2009-03-31) Marson, Silvia; Attia, Usama M.; Allen, David M.; Tipler, P.; Jin, T.; Hedge, J.; Alcock, Jeffrey R.; Rajkumar Roy; Essam Shehab
    This paper concerns the concept, the design and the manufacturing steps for the fabrication of a precision mould for micro-injection moulding of truly three dimensional microfluidic devices. The mould was designed using the concept of replaceable cavities to enable the flexible development of the complex microfluidic device and to reduce machining time and therefore costs during the prototyping, testing and subsequent production phase. The precision machining technique used for the cavity manufacture was micromilling.

    Through-life integration using PLM
    (Cranfield University, 2009-03-31) Gomez, M.; Baxter, David; Roy, Rajkumar; Kalta, M.; Rajkumar Roy; Essam Shehab
    It is widely agreed that organisations would benefit from a PLM implementation founded on a standard structure that integrates through-life information and knowledge. Thus, this paper describes a PLM data structure that provides a standard repository of data through all the stages of the lifecycle: conception, manufacture, and operation. This structure classifies the data into project, product, process and resource, and has been implemented into the PDM system Teamcenter Engineering as part of a case study with a vacuum pump manufacturer. A methodology to implement a knowledge structure from an ontology editor into PDM system is also presented.
