  1. Subject Knowledge Booster Course an introduction toCAD/CAM John Lee / Jenny Dein January 2008

  2. SKBC : CAD/CAM • aims: • to consider the increasingly important role of CAD and CAM in the fields of industry and commerce • to develop personal capability in the use of a range of CAD and CAM applications • to explore a range of designing and making strategies that make appropriate use of CAD and CAM

  3. what is CAD/CAM? CAD or computer aided design is the process of creating industrial product designs using computer software CAM or computer aided manufacturing uses computers to programme these designs into equipment that will actually manufacture the products. http://en.wikipedia.org/wiki/CAD

  4. CAD/CAMincreasingly central role in design and manufacture • increasing ‘customisation’ of products and reduced ‘time to market’ • the shift towards a ‘concurrent engineering’ philosophy • development of rapid prototyping techniques eg: stereolithography / laminate object modelling / digital printing

  5. concurrent engineering definition: the process of involving all branches of manufacturing in the initial design of a product. This shortens the manufacturing cycle because all departmental needs have been considered ‘concurrently’ and, as a result, there should be no need for redesign at any stage of manufacture. case study in concurrent engineering: Virgin Voyager – the ‘virtual train’ • Bombadier Transportation (in world’s top 40 most successful enterprises) • client – Virgin Trains : Project - ‘Voyager the train for the 21st century' • design team – 5 sites in 4 European countries • project design managed using 3D design software, CATIA and EDM software • timescale - 2 years – delivered on time (penalty clause for non-delivery £5m / month)

  6. computer aided design & manufacturefundamental to company success: case study – Polaroid • reducing ‘time to market’ • avoiding the cost of ‘getting it wrong’: Factor design concept 1 prototype 1000 tooling change 100 000 production change 1 000 000 product recall 10 000 000 Source : Pankhurst Design and Development (PDD)

  7. digital printinguse: digital textile printing enables the rapid prototyping of textile designs and products and eliminate the need for traditional time consuming and expensive sampling benefits: no start up costs no minimum print run designs printed on demand quick turn around – jobs normally completed in a week print directly onto fabric photographic image quality ideal for short print runs, engineered prints or customised designs example: Bar and restaurant interior schemes often require short print runs of bespoke fabric that would incur prohibitive origination charges if conventionally printed

  8. computer aided design & manufactureconsumer markets: case study –The Face Users can now superimpose a photo of their own face onto their 3D virtual model. This application meets the expectations of fashion shoppers who for years have been asking for more realistic avatars. Using The Face, they can now personalize their virtual selves and achieve greater satisfaction in their shopping and social experiences. For retailers this experience is expected to drive brand loyalty, higher customer satisfaction. Source: myvirtualmodel.com

  9. computer aided design “even the new generation of designer modellers need precise detailed information to create a computer model. The need for accuracy frequently conflicts with the initial stages of the design process, because ambiguity and imprecision are often hallmarks of creativity” R.Baker - designer ‘

  10. computer aided designwhere & when does it start? “basic elements of the product are still defined by conventional sketching and modelling” Julian Thomson – Chief Designer, Jaguar Cars

  11. CAD/CAMin schools DfES / DATA Initiative Aim:to modernise the design and technology curriculum through CAD/CAM • Pro/DESKTOP(September 1999) 3D solid modelling • ArtCAM(December 1999) 3D art & design modelling • Speedstep(February 2002) textile design • Pro/ENGINEER(October 2007) engineering design

  12. SKBC TIMETABLE Competence based CAD – 3D Solid Modelling (Pro/DESKTOP) Competence based CAD – Textile Design (Speedstep) Using CAD in presentations Corel Draw introduction Introduction to CAM Supported self study Accreditation opportunities
