The Research On Laser Cutting Die-boards

Because laser cutting die-boards has such characteristics as high efficiency , high quality , high accuracy ,etc, laser cutting die-boards replacing traditional manufacturing approach has more obvious trends day by day. Cutting die-boards with laser uses among packaging and printing industry more and more extensive, the relation between the cutting parameters, cutting mechanism , balance model of cutting energy and the reflectivity of die-boards to laser carry on research discussion has certain practice and theory meaning.Select the die-boards most frequently used in packaging industry as test materials , study the influence of cutting speed , focus position to cutting slot shape and width when cutting, draw result of the relation between laser power with cutting speed and the best cutting parameters when focus lies the position of lmm under the die-boards surface.Analyse the mechanism of laser that cutting die-boards, study the distribution of energy during laser cutting die-boards in an all-round way, set up energy balanced mathematics model of laser cutting die-boards. Calculating to this model, can draw the relationship of the parameters mainly , testing value and theory value is identical better. This model can be used for guiding production practices and optimizing the cutting parameters while laser cutting die-boards is using in packaging and printing industry.Mensurate the reflectivity of die-boards to laser experimentally with spread route of laser designed, study the variation tendency of reflectivity up to the angle of incidence and impact on reflectivity of different polarized state of laser, also compare the reflectivity of surface to laser to the reflectivity of side cutted to laser, analyse the differentiated reason. Set up the mathematics model of the reflectivity of die-boards to laser according to the basic principle of optics, the result of calculation of the model is identical better with testing data obtained, verify the exactness of the model. At present there is no research of the reflectivity of die-boards to laser, it is the first.
