Development of Laser Cutting Technology with High Quality of the Cut Surface

Abstract

This paper describes the development of thermal cutting technology aimed at the achievement of the best possible quality class in order to obtain smooth, aesthetic edges. The technology has been developed for two different types of materials: S235JR steel grade and AW-5754 aluminium alloy. The main objective of the developed technology is to eliminate the additional mechanical treatment of the surface following the laser cutting and to allow the classification of the obtained surfaces (without additional measurements) to the appropriate quality class defined by the ISO 9013 standard.
