has ability to download information to CAM equipment.

Question 2

Computer Aided Design (CAD) ADV

Answer 2

Faster to draw and edit designs
Higher level of accuracy

Question 3

Computer Aided Design (CAD) DIS

Answer 3

Initial set up costs are high
Software must be updated regularly, which can be expensive

Question 4

Rapid Prototyping

Answer 4

downloading a 3D CAD file to a machine that will produce a 3D model of the drawing.

Question 5

2 types of rapid prototyping

Answer 5

Stereolithography (SLA)

Fused Deposition Modelling (FDM) – 3D Printing

Question 6

Stereolithography (SLA)

Answer 6

CAD data is used to control a laser beam which draws each slice of the model, in turn, on the surface of a tank of resin.

Question 7

Fused Deposition Modelling (FDM) – 3D Printing

Answer 7

3D model from a CAD file by using software that slices the drawing into layers and guides an extruder head in paths to build the product from the bottom up

Question 8

Rapid Prototyping ADV

Answer 8

Faster than traditional modelling
Higher level of accuracy

Question 9

Virtual Modelling

Answer 9

creating 3D CAD models of the product so can be put into a virtual model of where it may be used.

Question 10

Rapid Prototyping DIS

Answer 10

initial set up costs are high
Software must be updated regularly, which can be expensive

Question 11

2 types of virtual modeling

Answer 11

Computational Fluid Dynamics (CFD)

Finite Element Analysis (FEA)

Question 12

Computational Fluid Dynamics (CFD)

Answer 12

simulation of the flow of fluids or gases in or around a product.

Question 13

Finite Element Analysis (FEA)

Answer 13

component stress analysis

Question 14

Virtual Modelling ADV

Answer 14

Highly accurate results

Products can be tested to eliminate problems before manufacture

Question 15

Virtual Modelling DIS

Answer 15

Initial set up costs are high
Software must be updated regularly, which can be expensive

Question 16

Computer Aided Manufacture (CAM)

Answer 16

computer controlled equipment to machine materials.

Turning
Plotter Cutting

Question 18

Laser Cutting

Answer 18

high energy laser beam is used to cut materials.
movement in X and Y axes controlled by CNC software.

Question 19

Routering

Answer 19

Used to cut materials too thick for laser cutters.
used to cut, trim and shape a wide variety of materials

Question 20

Milling

Answer 20

Milling machines move the bed of the machine in the X and Y axes.
fast, accurate
can be fitted with tools

Question 21

Turning

Answer 21

use of lathes to machine metal

Question 22

Plotter Cutting

Answer 22

2D CAD into CNC program that will use X and Y coordinates to cut out what has been drawn
usually is thin sheet

Question 23

First generation robots

Answer 23

pre-set programme and will carry on regardless of any external changes

Question 24

Second generation robots

Answer 24

sensors, which are used to feedback information to a central control computer
Pictures are taken at pre-set points and compared to pre-stored reference pictures

Question 25

Third generation robots

Answer 25

use AI detect changes or problems but also to modify its own program in response to the changes

Question 26

Beam transfer

Answer 26

move along x and y-axes and are generally used to pick up a component

Question 27

Arm

Answer 27

joined in a similar way to human arms shoulder, elbow and wrist

Question 28

Automatically Guided Vehicles

Answer 28

using sensors to follow a wire buried beneath the floor, or by using lasers which bounce off reflectors placed high up on walls.
