Model for thermodynamic point identification in laser cutting

Abstract

In recent years, laser cutting has been introduced and developed to such an extent that it is now thought to be one of the leading and indispensable manufacturing tools. At the present time, dross-free and accurately-cut parts are basically regarded as the major targets to aim for, because the costs and efforts associated with dross removal by postprocessing cut parts are considerable. Therefore, control of dross formation during laser cutting is an important factor in maintaining edge quality. The initial aim of this paper is to describe the importance of physico-mechanical material properties that need to be taken into account in modeling of laser material processing in order to control melting of the material.
