Abstract

Surface quality represented in the primary surface texture is the main parameter when dealing with surfaces in relative rotary and sliding motions. In conventional machining processes, if further quality in surface roughness is required, finishing and superfinishing machining operations are available. In case of extremely high resistive, hard and high strength materials conventional machining are highly uneconomical. The solution was found in cutting such hard materials is by using non-traditional processes. Plasma arc cutting was one solution. However, the surface quality as a response of the parameters involved in this process, namely gas pressure, cutting speed and standoff distance is not in the high finished quality. The aim of this paper is studying the effect of the cutting conditions of plasma arc cutting on the primary surface texture as assessed by the International standard Arithmetical Mean Average “R_a” for the produced parts. Experimental work was carried out on specimen made of Hardox400. The effect of the three considered parameters of plasma arc cutting were studied on the responded surface roughness. Results were analyzed using Minitab17 and binomial regression equations were deduced. Cutting speed showed greater effect on surface roughness and all has showed that surface roughness ranged from 5 to 5.5 μm.
