Answer 1

computer aided design

Question 2

CAM

Answer 2

computer aided manufacture

Question 3

computational fluid dynamics

Answer 3

a virtual modelling tool used to stimulate the flow of fluids & gases in or around a product

Question 4

finite element analysis

Answer 4

a virtual modelling tool used to carry out component stress analysis, e.g. vibrations and shock waves

Question 5

rapid prototyping

Answer 5

the process of downloading 3D CAD files to a machine which will produce a 3D model of a product

Question 6

selective laser sintering

Answer 6

a rapid prototyping process that uses a moving laser beam to sinter heat-fusible powders one layer at a time

Question 7

electron beam melting

Answer 7

a rapid prototyping process uses an electron beam to distribute layers of metal powder to make a model of a product

Question 8

stereolithography (SLA)

Answer 8

a rapid prototyping process that fabricates a part layer-wise by hardening a photopolymer with a guided laser beam

Question 9

fused deposition modelling

Answer 9

a rapid prototyping process in which a filament of wax or polymer is extruded onto the existing part surface from a workhead to complete each new layer
