Abstract:
Technology today in metal cutting process require high quality cut surfaces and good dimensional correctness without further operation. Plasma arc cutting process does high temperature and high velocity contracted arc via a amount of gas between the electrode and the work material to be engrave. There are a variety of process parameters such as arc voltage, arc current, gas pressure, cutting speed, standoff distance and gas flow rate that affect the quality distinctiveness of plasma cut like kerf generated, bevel angle, heat affected zone (HAZ) and surface finish. In this paper, Plasma Arc Cutting (PAC) shows the Cutting Speed (mm/Sec.), Current (A), Pressure (bar) on SS304 Material having the density 8.03 g/cm3. In this Experiment we have done Experiment by using full factorial design methods and regression analysis equation for Surface Roughness by performing cuts of different run sets of L27 orthogonal Array to find out optimal run set of Speed, Current, Pressure which gives the smooth surface. The regression analysis has been used for the development of empirical models able to describe the effect of the process parameters on the quality of cutting.And also evaluated the machining parameters of hot turning of stainless steel by applying ANN and RSM and found that the turned part were incorporated into ANN-based Neurointelligence software package and design expert. Here we determined the grey grade values using Grey Relation Analysis.
