Influence of cutting parameters on heat affected zone after laser cutting

Abstract

The contribution deals with method about the thermal cutting of materials specifically with the laser technology. In the theoretical part is described its principle, capabilities and use of the laser in the process of machining mainly procedure of cutting the material using a laser bunch. The experimental part is focused on cutting the cobalt alloy by continuous laser CO2 and the influence of technological parameters during the cutting on final quality of the cutting area. Based on metallographic analysis was determinate suitable technological parameters, have been achieved the lowest heat influence material.
