Abstract

Abstract This paper describes a numerical modeling method that utilizes stress equations derived from surface topography created by laser cutting technology. The explanatory ability of the geometric phenomena of the created surface topography is an essential analytical tool for the physical-mathematical formulation of the principle of laser cutting processes. As experimental meaterial was used structural steel of type S355J0 and CP-Ti Grade 2. A cutting machine from Prima Industry - ZAPHIRO / CV5000 was used. The new derived relations for the determination of the residual stress were determined and verified by experiment. The objective of this paper is to contribute to the understanding of process-related stresses and deformations generated by laser cutting technology, particularly by ultrasound testing of stress inside the material and significantly influenced by surface topography.
