Description
Technical Field
The invention relates to the technical field of laser cutting, in particular to a laser cutting system and method for a bevel lampshade.
Background
Laser cutting is a technique in which a material is irradiated with a high power density laser beam to rapidly melt, gasify, ablate, or reach a fire point. During laser cutting, molten material is blown away by a high velocity gas stream coaxial with the beam, thereby effecting cutting. Compared with other thermal cutting methods, the laser cutting method has the characteristics of high cutting speed and high quality. The current manufacturing of bezel lamp covers uses a laser cutter to cut the bevel, which creates geometry at the bezel edge by cutting the bezel lamp cover at an angle.
Current laser cutting devices typically focus a high energy density laser beam onto a bezel when the bezel is being laser cut, which causes the region to heat locally until the melting point is exceeded, causing evaporation or melting of the material surface. However, in the traditional laser cutting method, a worker controls the laser cutting device to work by moving the lens, and the cutting process cannot be regulated and controlled according to the characteristic properties of the bevel lampshade, so that the current laser cutting method is too single, and is easy to cut by mistake or misplaced, so that the working efficiency is low.
