摘要
激光具有极高的发光强度,同时又具有方向性、相干性、单色性,激光通过激光器产生后由反射镜传递并通过聚集镜照射到加工物品上,使加工物品(表面)受到强大的热能而温度急剧增加,使该点因高温而迅速的融化或者汽化,配合激光头的运行轨迹从而达到加工的目的。
激光雕刻:主要是在物体的表面进行,分为位图雕刻和矢量雕刻两种:
位图雕刻: 我们先在PHOTOSHOP里将我们所需要雕刻的图形进行挂网处理并转化为单色BMP格式,而后在专用的激光雕刻切割软件中打开该图形文件。根据我们所加工的材料我们进行合适的参数设置就可以了,而后点击运行,激光雕刻机就会根据图形文件产生的点阵效果进行雕刻。
矢量雕刻:使用矢量软件如Core IDRAW,Auto Cad,Illustrator等排版设计,并将图形导出为PLT,DXF,AI格式,打标机,然后再用专用的激光切割雕刻软件打开该图形文件,传送到激光雕刻机里进行加工。

ABSTRACT
Laser with high luminous intensity, but also has direction, coherent,monochromatic. Laser by laser generated after reflected by the mirror and through the assembled mirror irradiated to transfer processing articles,Make goods processing ( surface ) is a strong heat and temperature increase sharply,The point because of high temperature and rapid melting or vaporizing, combined with laser head so as to achieve the purpose of processing the running track.
Laser engraving: mainly in the surface of the object, bitmap and vector for carving sculpture two:
Bitmap carving: we first in PHOTOSHOP we need to carve the graphics were processing and conversion to a monochrome BMP format,then in a special laser engraving cutting software open the graphic to the processing of the material we are appropriate parameters can be, and then click Run, laser engraving machine will be based on graphics files generated lattice effect carving.
Vector carving: using vector software such as Core IDRAW, Auto Cad, Illustrator layout design, and graphics will be exported as PLT, DXF, AI format, marking machine, then the special laser cutting engraving software to open the graphic file, transmits to the laser engraving machine for processing.
