IRJET- A Review Paper on Optimization of Influence Parameter of EN-45A Material using Plasma Arc Cutting Machine (original) (raw)

In the previous few decade years, there has been a huge amount of machining research and technological advancement. With the increase in market competition and the need for high accuracy, non-conventional machining is currently becoming the lifeline of any sector. Plasma Arc Machining is one of the most important non-conventional machining processes. Its great accuracy, capacity to finish machining any hard material, and ability to manufacture complicated shapes all contribute to its market demand. The aim of this review paper is to determine the effects of various process variables on the machinability of EN-45A material using the Plasma Arc Cutting Process, as well as the optimum condition (best setting) for achieving maximum Material removal rate (MRR) and minimum Surface roughness (S.R), Kerf width (K.W), and Bevel angle (B.A). Cutting is possible using a plasma arc cutting machine by varying process parameters such as cutting speed, arc current, standoff-distance, and plasma gas pressure to obtain changes in reaction variables such as surface roughness, bevel angle, Kerf width, and material removal rate.
