Abstract

The The basic purpose of this study was to determine the impact of machining parameters on the surface roughness of AISI 420 martensitic stainless during the CNC turning and develop a mathematical model. AISI 420 martensitic stainless steel was selected for machining with precise vibration-less machinery. Rotational speed, feed rate, and depth of cut were considered as input parameters while surface roughness was set as an output parameter. L27 orthogonal array was used to optimize the process parameters, ANOVA was calculated and regression model was developed. Through the CNC machine, the idea of the near net shape manufacturing (NNM) can be possible through optimization of machining parameters. The rotational speed selected 1000, 1500, 2000 rpm and feed picked as 0.1, 0.2, 0.3 mm/rev and depth of cut were selected as 0.25, 0.45, and 0.65 mm for observation. The best parameters were obtained was at 1000 rpm, 0.65 mm depth of cut and 0.3 mm/rev is best machining parameter for surface roughness value.
