What’s Laser Cutting?
Laser cutting is the process of cutting or giving shape to a material using high-powered laser beam.
It is directed by CNC i.e Computer Numerically Controlled machine from a CAD vector file.
How does it work?
There’re mainly two types of lasers used in cutting:
CO2 lasers and neodymium (Nd)
Neodymium yttrium-aluminium-garnet (Nd-YAG).
We use only CO2 lasers, so for ease of this introduction I will focus on them.
When a current is passed through the laser tube, laser beam is emitted from it. This points the beam through a focal lens in the machine
