How does laser cutting work?

Laser cutting is a production process that involves cutting material using a powerful and highly accurate laser that focuses on a small area of the material. The high power density results in rapid heating, melting and partial or complete vaporization of the material.

As the heat affected area is small, around 0.5 mm, cut parts show very minor deformation. Usually, a computer directs the high-power laser at the material and traces out the path.

The machine works by cutting or engraving a slab or slice of the material that can have various thicknesses. The thickness of material that can be cut is dependant on the power of the laser.. Generally material thickness is in the range of 1 to 10 mm.
