Optimization of Nitrogen Use Efficiency in Cutting of Austenitic Stainless Steel by a Fiber Laser
Apstrakt
In metallurgical processes, metal sheet cutting is usually a basic
technological operation that needs to be performed. All other
technological operations follow the procedure of metal sheet cutting, with
the final aim of manufacturing a final product. Machines used for that
basic metal cutting operation shall be reliable, efficient, fast, and relatively
easy to work with. While working with a laser, the authors noticed the
inefficiency of cutting with nitrogen. Nitrogen bottles got empty too
quickly, which caused additional costs. Inefficient, i.e., excessive nitrogen
consumption requires a more frequent supply of nitrogen. During the
COVID-19 pandemic, nitrogen was not always available, as suppliers
shifted to manufacture oxygen bottles for medical needs. Therefore, the
authors engaged in finding solutions to reduce the consumption of nitrogen
at cutting. The mentioned problem was studied within the experiment that
focused on the optimization of nitrogen use during fiber ...laser cutting, the
procedure, and results of which are described in this paper. Specimens of
different cutting parameters were prepared and cut to measure their
roughness and burr height. The collected data were used to create a
mathematical model with an ANOVA table. The experiment resulted in the
determination of optimal cutting parameters achieved by the lowest
possible cutting gas pressure.
