Rapid Prototyping Methods
CNC (Computer Numerical Control)
Not able to mill the whole design in one setup
Limitation of tool-bit (cutter diameter) size to produce small details
Deciding the depth of cut, the tool-bit size
Deciding how to hold the part on the machine table
How it works?
Remove material from a solid workplace until the desired shape
The process is programmable, text control by NC program
Process is programmable
Can be cut on hard-metallic material
Smooth surface finish
How to create the NC program?
Manual programming (Text file)
Can be generated from Computer Aided Manufacturing (CAM) system
