The Research for Control of the Laser Beam Trajectory on Surface Hardening Using NC
Laser surface hardening is widely used. The complexity of the surface restricts its application. To solve this problem, it is necessary to study the path of the laser spot. By comparison the difference of CNC cutting machine and laser processing machines, the control system of laser spot is built. And the method of alignment for work coordinate system is obtained. NC programming model of the laser beam is established using CAM software. The change of area of spot when laser beam projected to the different normal angles surface was analyzed, and it is get the relationship of normal angles and feed rate. The complex surface laser surface hardening is realized.
