Subject Knowledge Booster Course an introduction to CAD/CAM John Lee / Jenny Dein January 2008

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

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. what is CAD/CAM?

CAD/CAM increasingly 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

concurrent engineering case study in concurrent engineering: Virgin Voyager – the virtual train Bombadier Transportation (in worlds top 40 most successful enterprises) client – Virgin Trains : Project - Voyager the train for the 21 st 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) 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.

computer aided design & manufacture fundamental to company success: case study – Polaroid reducing time to market avoiding the cost of getting it wrong: Factor design concept1 prototype1000 tooling change production change product recall Source : Pankhurst Design and Development (PDD)

digital printing use: 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

computer aided design & manufacture consumer 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

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

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

in schools CAD/CAM in 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

they can be used: as communication tools between designer and client / manufacturer to assist in design verification and optimisation to prove performance - eg. functionality, fit / assembly etc as test samples for market research concept models enable designers to visualise their designs in three dimensions concept modelling using CAD
