Influence of cutting parameters on heat-affected zone after laser cutting

Abstract

The article deals with a method of thermal cutting of materials, specifically with laser technology. The theoretical part describes its principles, capabilities and use of laser in the process of machining, mainly the procedure of cutting material using a laser beam. The experimental part is focused on cutting the cobalt alloy by a continuous CO2 laser and the influence of technological parameters during cutting on the final quality of the cutting area. Suitable technological parameters were determined on the basis of metallographic analysis, and the lowest heat influence on the material was achieved.
