Laser cutting 2D

2D Laser cutting burns and creates cuts in sheet surfaces using high-intensity light

Illustration of Laser cutting 2D

The process

2D Laser cutting uses a laser resonator to create a laser beam [1] which is directed to the cutting head [2] where it is focused through a lens [3.] A cutting gas [4], usually oxygen or nitrogen, is applied to the cutting head between the lens and the nozzle [5] and surrounds the laser beam during the cutting process. The laser beam is focused through the lens toward the workpiece that is heated, melted and partially evaporated. The laser head follows a contoured contour, which creates a continuous cut.
The melt that occurs during the cutting is blown away by the cutting gas. This also protects the lens from splashes from the cutting area and also keeps the laser beam free from vapors that could absorb parts of the laser beam.
When using oxygen, instead of inert gas, a higher cutting speed can be achieved as it contributes to a faster combustion of the material but then leaves an oxide layer on the cutting surface which can be negative in some cases.
The cutting head is positioned using a portal system.
By nesting, details can be programmed and placed in such a way that waste material is minimized.
