Investigating the effects of cutting parameters on materials cut in CNC plasma

Abstract

Complex-profile surfaces, of which measurement precision is not important, are cut serially using CNC plasma. These materials cut using CNC plasma are assembled with different manufacturing techniques. These materials can also operate under high pressure and resistance. In this study, S235JR sheet materials (4, 6, and 8 mm thick), used in pressure vessels, were cut using the CNC plasma cutting machine at different cutting speeds, amperes, and arc voltages. Temperature distribution, thickness of heat-affected zone (HAZ), surface roughness, and hardness were measured from the material cut at these different values. Based on values obtained from measurements, the ideal cutting conditions were identified for the materials exposed to the cutting procedures.
