Plasma arc cutting is a non-conventional manufacturing process that has potential for modern day metal cutting demands with
good dimensional accuracy and high-quality surfaces without any extra operation. In this experimental study, AISI 304, AISI 430 and EN
S235JR sheet materials having 5 mm. thicknesses, has cut with plasma arc cutting. Each material has cut with 6 different variations.
Current, cutting speed, arc voltage, gas pressure and gas flow rate have been changed as process parameters. The quality of the cut has
been monitored by measuring the edge roughness, the hardness of the heat-affected zone (HAZ) and the results has compared.
