Experimental Results for Laser Cutting of Stainless Steel Plate 5 mm in Thickness

Abstract

Article deals with the temperature measurement and analysis of temperature fields by the process of laser cutting. A direct path was carried out during experiments on a stainless steel plate of 5 mm in thickness. The temperatures were measured by four K-type thermocouples using digital converter NI USB9211 in order to find out the temperature distribution in the direction perpendicular to the central plane of the cut. Moreover, the dimension of the kerf width was determined using confocal laser scanning microscopy. Obtained results of temperature measurements will be used for verification of developed simulation model and results of numerical simulation of laser cutting process obtained by ANSYS and SYSWELD software.
