激光切割是利用經(jīng)聚焦的高功率密度激光束照射工件，使被照射的材料迅速熔化、汽化、燒蝕或達到燃點，同時借助與光束同軸的高速氣流吹除熔融物質(zhì)，從而實現(xiàn)將工件割開。激光切割屬于熱切割方法之一。

一般來說，激光切割質(zhì)量可以由以下6個標準來衡量。

⒈切割表面粗糙度Rz

⒉切口掛渣尺寸

⒊切邊垂直度和斜度u

⒋切割邊緣圓角尺寸r

⒌條紋后拖量n

⒍平面度F

Laser cutting is the use of focused high-power density laser beams to irradiate the workpiece, so that the irradiated material rapidly melts, vaporizes, ablates, or reaches the ignition point. At the same time, the molten material is blown away by high-speed air currents that are coaxial with the beam to achieve the workpiece. Cut open. Laser cutting is one of the hot cutting methods.
In general, the quality of laser cutting can be measured by the following six standards.
Cutting surface roughness Rz
Size of incision slag
Vertical degree and slope of the incisor
Everywhere cutting edges rounded dimensions R
Drag after <UNK> Stripe N
Plane F
