Laser cutting has greater flexibility than other conventional processing methods. First, as with other thermal cutting methods, as a thermal cutting process, other methods cannot act as a laser beam on a very small area, resulting in a wide slit, a large heat affected zone, and significant workpiece deformation. Lasers can cut non-metals, while other thermal cutting methods do not.
In general, laser cutting quality can be measured by the following six criteria.
1. Cutting surface roughness Rz
2. Cutting slag size
3. Trimming verticality and slope u
4. Cutting edge rounded size r
5. After the stripe dragged n
6. Flatness F
