Research on Surface Roughness by Laser Cut

Abstract

Laser cutting is one of the most industrial applications. Laser cutting with oxygen is used primarily for cutting of mild and low-alloyed steels. Cut surface quality is a very important characteristic of laser cutting that ensures an advantage on other contour cutting processes. This paper gives results of the experimental research referring to the determination of surface indicators obtained by laser cutting. The relationships between roughness parameters are given by linear and exponential equations.
