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.
The article is focused on the issue of heat treatment. The cooling curves were obtained for Isorapid 277HM with an experimental way of temperature measuring and their statistical processing. Material data of the material pattern 50CrMo4 were obtained from the Material Data Sheet (MDS) of Deutsche Edelstahlwerke (***, 2011). The cooling oil Isorapid 277HM was agitated with energy input 1.65 J.s −1 .kg −1 and had a constant temperature of 50 °C. In the follow of this article were showed the experimentally obtained results: geometry distortion,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
