Optimization of Turning Operation Parameters For Stainless Steel To Minimize Surface Roughness

Mechanical

The present work involved associate experimental study of turning on primary solid solution chrome steel of grade AISI 202 by a TiAlN coated inorganic compound insert tool. the first objective of the following study was to use the Response Surface Methodology so as to work out the impact of machining parameters viz. cutting speed, feed, and depth of cut, on the surface roughness of the machined material. the target was to seek out the optimum machining parameters therefore on minimize the surface roughness and gear wear for the chosen tool and work materials within the chosen domain of the experiment. The experiment was conducted in associate experiment matrix of twenty runs designed employing a full-factorial Central Composite style (CCD). Surface Roughness will be measured employing and gear wear with the assistance of a Toolmaker‟s magnifier. The info was compiled into MINITAB ® seventeen for analysis. the connection between the machining parameters and also the response variables (surface roughness and gear wear) were modelled and analysed mistreatment the Response Surface Methodology (RSM). Analysis of Variance (ANOVA) was wont to investigate the importance of those parameters on the response variables, and to work out an equation for the response variables with the machining parameters because the freelance variables, with the assistance of a quadratic model. Main effects and interaction plots from the analysis of variance were obtained and studied beside contour and 3D surface plots. The quadratic models were found to be vital with a p-value of zero.033 and 0.049. Results showed that feed is that the most important issue moving the surface roughness, closely followed by cutting speed and depth of cut. the highest 3 optimum settings for finishing up the machining were obtained from Response Surface Optimizer and are shown within the results section.
