Abstract
In order to evaluate the surface quality of a laser cutting die-board,the relationship between carbon layer attacked to die-hoard surface and laser cutting parameters were analyzed through three methods,i, e.macroscopic observation,microcosmic observation and carbon content measurement.Results indicate that carbon area will extend with the decreasing of cutting speed.The surface striation becomes prominent with the increasing of cutting speed at the same laser power,while diminishes or vanishes with reducing the speed.In the case of lower speed, carbon attacked to surface will decrease with increasing of laser power.In the case of higher speed,carbon attacked to surface is almost the same with increasing of laser power and surface striation is not so prominent.Carbon layer is distributed along the wood grain, while honeycomb distributed perpendicular to the wood grain.Both cases exist holes and the hole diameter reduces with the decreasing of speed.
