-Alfie Turner
Using CAD to draw designs, versus using hand-held techniques give greater….
Accuracy
-Alfie turner
A vinyl cutter is a good example of what type of machine?
a CNC, computer numerically controlled machine.
-Alfie turner
What does FDM stand for?
Caspar Tyser
Filament Deposition Modelling.
When is ICT used?
Caspar Tyser
Throughout the design process and in one-off, batch and mass manufacturing
What does CIM stand for?
-Oscar Lawson
Computer Integrated Manufacture
How does 3D printing work?
-Oscar Lawson
It is an additive process where layers of plastic are built up on top of each other by a machine
How does CNC milling work?
-Oscar Lawson
The opposite of 3D printing, it is a wasting, subtractive process. The finished product is machined and cut from a solid block into the desired shape
a 3D printer is a good example of what type of machine?
-Oscar Lawson
a CNC - computer numerically controlled - machine.
What is rapid prototyping?
-Oscar Lawson
Quickly making a scale model of a part or assembly process. It often uses 3D CAD data and can check for accuracy, fit and aesthetics
How does CAD/CAM help the design process?
Yan K
Helps the designer to speed up development and ensures quality
Is CAD/CAM more accurate than hand tools, or less accurate?
Yan K
CAD is more accurate than hand tools and manual processes.
is CAD/CAM more or less repeatable that manual processes?
Yan K
CAD is more repeatable than manual processes, but it not necessarily more reliable.
Is CAD quicker or slower than drawing by hand.
Yan K
It depends on the detail required.
A quick communicative sketch is often quicker by hand, but
A detailed engineering / manufacturing drawing is often quicker using CAD.
What type of manufacturing process is 3D printing
-Krystian shanahan
Additive
What type of manufacturing process is 3D milling
-Krystian Shanahan
Subtractive
What might rapid beprototyping be used to test for?
-Krystian shanahan
Accuracy and quality of fit between components, or aesthetic qualities
How are materials held securely during CIM processes
-Krystian Shanahan
Using automatic chucks and compressed air
What is a disadvantage of CNC milling vs. 3D printing when trying to conserve materials?
Ivan k2
CNC milling is a wasting / subtractive process. 3D printing is additive.
What is the most obvious examples of an additive process?
Ivan k2
3D PRINTING
Where CAD is concerned, Scanners, Digital cameras and Digitisers are forms of what?
-Lucas M
Scanners, Digital cameras and Digitisers are forms of inputs for CAD.
What are the three stages of CAD?
-Lucas M
Input
Process
Output
What is the one product which carries out the processes of CAD?
-Lucas M
Computers
Where CAD is concerned, Plotters, Printers, Vinyl cutters, 3D printers, and Machine tools are forms of what?
-Lucas M
Plotters, Printers, Vinyl cutters, 3D printers, and Machine tools are forms of OUTPUT for CAD
What type of subtractive / wastage machine would be used for rapid prototyping?
-Lucas M
A CNC milling machine is a subtractive manufacturing method for rapid prototypeing.
Quality and safety controls are only advantages of CAM when…
-Ssnehnil G
When the process has been checked through for human error in the design or set-up.
A LASER cutter is a good example of what type of machine?
-Humphrey Marsh
A CNC machine

Yes
Is Stereolithography an example of Rapid Prototyping?
-Oscar Mabon
Yes
Are Extrusion nozzles part of a 3D printer?
-Oscar Mabon
Yes
Is Accuracy an advantage of CAM production?
-Oscar Mabon
Yes
