Description
The overall aim of this module is to enhance the student’s skill, knowledge and competence at producing models, virtual prototypes, engineering drawings and design documentation for mechanical, precision and tool design activity . Students will be introduced to specialist plastic part and mould design modules and will undertake complex surface & solid modelling. Students will design simple injection moulds, applying their knowledge of polymers and polymer processing parameters.
Learning Outcomes
On completion of this module the learner will/should be able to;
1.
Utilise surface modelling techniques in the creation of complex part and product design.
2.
Undertake the design of plastic injection moulded products and carry out basic mould design using specialist 3D mould design module.
3.
Use fused deposition modelling system to create prototype models and describe current rapid prototyping technologies.
4.
Create complex part and assembly models and produce working drawings and documentation necessary to detail plastic products, mould design and precision design project work.
5.
Apply knowledge of important polymer properties and process parameters to the design of simple moulds and dies.
Teaching and Learning Strategies
In addition to the normal CAD lectures and practical classes, Designers / Engineering Practitioners working in industry will be invited as guest lecturers and site visits companies will be arranged, where possible.
Module Assessment Strategies
Continuous assessment will involve the assessment of all assignments undertaken in class, design project activity completed independently and an end of term in-house assessment test.
Repeat Assessments
This will normally require repeat attendance; however, for students with high attendance, a repeat assignment may be set, at the discretion of the Examination Board.
Indicative Syllabus
Surface modelling: Surface creation tools, surface bodies, surface controls, knitting surfaces, trimming surfaces, moving, deleting, replacing faces, thicken tool.
Plastic Part/Mould Design: Mould design module, shell, draft, draft analysis, undercut detection; parting lines; shut−off surfaces; parting surfaces; core and cavity creation; standard mould bases; mould design detailing.
Rapid Prototyping: Current Rapid Prototype technologies, stereo lithography, fused deposition modelling, laminated object modelling, selective laser sintering, 3D printing, file formats and production of .stl files, strategies for prototype production, production of FDM prototype models of an engineering mechanism.
Polymer melt flow: Shear viscosity, melt flow profile, shear thinning,visco-elastic behaviour, pressure drops.
Polymer process parameters: Key extrusion and injection moulding process parameters, screw speed, temperature, residence time, injection speed, injection pressure, polymer properties and process parameter influence on mould design and part quality.
Drawing: Modelling, drawing and detailing of complex mechanical, tool design and precision engineering parts, products and design project work, including drawings for plastic products, mould designs and rapid prototypes.
