Module Aims:
Develop knowledge of manufacturing techniques such as Manufacturing Technology, Design, Quality
Assurance, Robotics and CADCAM. Cost benefit analysis will be used in considering design options.
Expected Learning Outcomes
Knowledge and Understanding:
At the end of this module the student should be able to:
1. Design a product that may be manufactured to be commercially viable
2. Use CADCAM software effectively in the design process
Transferable/Key Skills and other attributes:
 Managing self
 Problem solving
 Numeracy
 Working with others
 Use of software packages
Assessment: please indicate the type(s) of assessment (eg examination, oral, coursework, project) and
the weighting of each (%). Details of indicative assessment should also be included.

Learning and Teaching Strategies:
Delivery will be by a series of interactive classes using project-based design exercises and case
studies with occasional note-based lectures. The learning element will be evaluated by carrying out the
assessment laid out above which will ensure the learner has the opportunity to achieve all the
stipulated outcomes.
Although specified to be stand-alone, this module may be integrated with other relevant modules
(listed in Aims) for delivery.
Syllabus outline:
1.
Economic Manufacture
Manufacturing methods: selection of methods, key design factors:- design form, materials type
and properties, quality requirements, available equipment, processing capability, costs,
labour skills. Analysis of methods, design criteria, decision criteria (which, why, alternatives,
suitability).
Total Costs: material, labour, overheads; fixed and variable costs; relationships of manufactuing
method, complexity of design form, surface finish, relative cost. Break-even analysis.
Standardisation: BS/ISO/industry-specific standards relevant to design form/materials; standard
components/parts/fittings; preferred number methods for detection and standardisation; cost
advantages of standard parts (design, development, tooling, plannng, choice, labour); ease
of replacement, interchangeability. Advantages and disadvantages.
Process requirements: factors affecting material requirements:- form, size, weight, processing
method, quality, quantity, availability, service life, characteristics (mech., elect., chemical).
2.
Economic Assembly
Appropriate Mecthod: analytical (questioning) approach to select method. 'Value Engineering'
approach: evaluate specification, validity of product; minimise variation between similar
components, sequencing of assembly stages; symmetrical and asymmetrical parts; justify
number of components used; suitability for automatic feed and assembly (FMS and robots),
unidirectional component location, ease of handling, positioning, stacking, accessibility within
assembly.
Features of good design: location of spigots, flanges, tenons; locating faces; accessibility,
alignment, families of parts (groupings).
3.
Tolerances and Dimensions
Principles: Geometrical tolerancing:- description and application for components, sub-assemblies,
assemblies. Tolerance build-up. Use of BS, ISO standards. Design, manufacture, inspection.
4.
Computer-aided Manufacture
Software: Numerical control of assembly. Material selection.
