Summary of Content

The aim of this module is to develop an understanding of the use of fully integrated software in design and manufacture of products and the rapid prototyping techniques which can be used to reduce time to market of new products.

Syllabus

Modelling Methodology: Idealisation, element selection, loading, boundary conditions, symmetry, load cases. Static Analysis: Small displacement linear elastic solution planar/axisymmetric structures. Analysis Validation: Convergence, nodal/element results, results processing. Solid Modelling; parts containing sweeps and blends, assemblies, drawings of parts and assemblies, exploded views, assembly datums, dimension clash, photorendering. Computer Aided NC programming; set up of manufacture model from solid model, specification of machine tool and cutting tools, identification of surfaces to be machined, creation of machining sequence, post processing. The aforementioned to cover both multi axis milling and turning. Evaluation of polymer components for moulding; use of software to create the mould model from component solid model, position of sprues and runners, optimisation of material flow in mould. Rapid prototyping; comparion of different rapid prototyping techniques, surface finish, component size, accuracy etc; cost of machines and prototype components. Application of rapid prototyping in the industrial environment.

Learning Outcomes

On completion of this module the student should be able to:Utilise a feature based solid modelling package to create assemblies and drawings from component parts.Use an FE Package to analyse a simple model.Generate NC codes to machine solid geometry features using an integrated feature based solid modelling and multi axis NC manufacturing programming) package.Use an integrated feature based solid modelling and manufacturing (mould flow simulation) package to assess the mouldability of components.Specify/apply rapid prototyping to an industrial environment to assist in reducing time to market of complex shaped components.

Teaching / Learning Strategy

Practical use of an integrated modelling and manufacturing package is the learning strategy used for most of this module; there will be a number of lectures and seminars covering rapid prototyping.
