Influence of workpiece thickness and cutting speed to kerf shape and stria formation in laser cutting of acrylic resin plate

Abstract

In laser cutting process, the main factor to decide a maximum cutting speed and maximum thickness of a material is the laser power itself. Besides that, various factors such as process parameter, optical effect on a material and the material thermal characteristic also complicates the problem to decide maximum cutting speed and maximum thickness of a plate. In this experiment, formation process of a kerf by laser cutting was examined from the viewpoint of the heat input based on observing the laser cutting part of acrylic resin plate
