Study on Laser-engraving Technique of Wood Materials

There are three types of laser-engraving of wood materials: cut-engraving,intaglio and relief engraving.Cutting mechanism on the laser-engraving is as same as that on laser-cutting.Region material cutting can be achieved by multiple notches which close together one by one.Shapes of cross sections of the notches appear letter V.Notch sizes increase with laser current and decrease with feed speed,as well as changing values of depth of the notch are much bigger than that of width of the notch.
