MECT06010 2013 Design and Engineering Technology

Describe the design process, employ recognised design techniques and appreciate the role of the mechanical designer.

Produce freehand schematic, orthographic and pictorial sketches of engineering parts and products.

Use a solid modelling CAD system to create 3D models of parts and assemblies and to produce detail and assembly drawings of engineering parts, products and devices, in an efficient and conventional manner.

Read and interpret engineering drawings and produce drawings which conform to ISO standards.

Describe common machining processes employed in manufacturing, such as turning, milling, grinding, electro-discharge machining, laser and plasma cutting.

Use standard machine tools, workshop equipment and metal joining processes to undertake basic practical manufacturing tasks.

In addition to the normal CAD and Engineering Technology lectures and practicals, Engineers working in design and manufacutre in industry will be invited as guest lecturers and site visits will be arranged, where possible.

The assessment of CAD will involve the assessment of all assignments undertaken in class, design project activity completed independently and an end of term assessment test.

The assessment of Engineering Technology will involve the assessment of all practical assignments undertaken in the workshop and an end of term written assessment test.

The Design Process: Stages in the design process, design methods, procedures and tools, design strategies and plan‑of‑action for a particular design project.

Freehand Sketching: Freehand sketching techniques, orthographic, isometric and oblique projection, sketching of pictorial, detail and assembly drawings, sketching of design projects.

Computer Aided Design: Efficient part modelling tools and techniques, use of wizards and toolboxes for creating standard parts, holes and features, introduction to assembly modelling, insertion and arrangement of parts, views, patterns, instances, assembly mates, standard, advanced and mechanical mates, assigning colours, materials, part numbers and descriptive titles.

Engineering Drawing: ISO standards and conventional representation of parts and assemblies, creation of detail drawings, complete shape description, dimensioning implications and feature specification, creation of assembly drawings, sectional assemblies, balloon references, bills of materials ,creation of a complete set of working drawings for an engineering product.

Reading Drawings: Determination of form and geometry, shape description, determination of size and tolerance, size description, specification of manufacturing instructions, items and quantities in engineering assemblies, schematic drawings, electrical diagrams.

Individual Design Project Work: Design brief, design specification, concepts and alternatives, concept sketches, evaluation of alternatives, details drawings, project reports and presentations.

Functional Design: Role of the designer, role design plays in product success, use of standard features, fasteners, parts and materials, design for machinability, manufacturability, assembly and maintenance.

As the focus of the design element of the module is mechanical design, the material covered and examples used will integrate engineering design philosophy, introduce students to common mechanical/mechatronic devices and highlight the approach adopted by designers in industry.

Health and safety in the workshop. Health and safety standards. Approach required for machining and workshop practical activities. Cutting speeds and feeds. Measuring equipment and bench tools. Common machine tool elements and machine principles - power transmissions, motors, bearings, gears, cams, belts, etc.

Machining and manufacturing processes such as; drilling, turning, milling, grinding, spark erosion, laser cutting, plasma cutting, CNC machinng, bending, shearing, soldering, welding, screwing & tapping and bench work.
