Compared with other conventional machining methods, laser cutting with greater flexibility. First of all, compared with other thermal cutting method, the same as thermal cutting processes, other methods like laser beam that role to a very small area, resulting in wide cut, heat-affected zone of large and significant deformation of the workpiece. Laser cutting Nonmetal, and other cutting methods are not.
In General, the quality of laser cutting can be measured by the following 6 criteria.
• Cutting surface roughness Rz
• Incision hang slag
• Trimming and vertical tilt u
• Cutting edge fillet size r
⒌ stripe drag n
• Flatness f
