Prototyping methods
Subtractive
Laser Cutting
EDM
CNC/NC
Computer Numerical Control
A process in which the pre-programmed computer software dictates the movement of the tool while removing material from a raw material
The process is programmable by NC program
How to create a NC program
Manual Programming
Can be generated from Computer Aided Manafacturing
Advantages
The process is programmable
Can cut on hard metallic materials
Smooth surface finish
Disadvantages
Can only cut from the top
work piece needs to be clamped
Deciding the depth of cut, the tool-size
Limitation of tool-bit size to produce small details
Addittive
Wet Process
Dry Process
