Title of Current Research Program:- 'MODEL INTEGRATION WITHIN A DESIGN BY VIRTUAL MANUFACTURING ENVIRONMENT' Project Aims To research the new 'design by virtual manufacturing approach' in order to integrate the disparate models of cost, time, geometry and physics, which form its basis. To verify the integration methodology, by means of a flexible forming system, through the production of a range of metallic fastenings, from the virtual manufacturing design data. Introduction A number of approaches have been used in the past to integrate the design and manufacturing tasks, such as feature based modelling, or feature recognition systems but these have met with limited success, either requiring input from a process planner or restricting the designer to a number of predesign features. A new approach was developed by Jaques and Billingsley entitled design by manufacturing simulation. Within this new approach manufacturing modes are used as the primary input to design. By directly actuating a simulation of machine tools and displaying the response of the material to this machine tool action, manufacturing constraints are captured at the design stage. Both manufacturing and design data are generated concurrently, leading to reduction in prototyping development lead times. This Virtual Manufacturing System consists of a number of independent models of:- geometry, cost, time and physical constraints. The integration of these models requires a vast quantity of manual input and human interpretation. It is the integration of these models which forms the basis of the research.
