Sahu, Binaya Kumar (2015) Experimental Investigation of Turning of Austenitic Steel. BTech thesis.
In this work, turning of Austenitic Stainless steel of grade AISI 202 using an uncoated carbide insert tool was done at specific input values of speed, feed and depth of cut. At first, we determine how the outputs like cutting force, surface roughness and the tool wear are related to the input parameters. At first the layout of the experiment was made using full factorial composite design. Then the experiment was conducted. First the cutting power is measured using the power meter and from the calculated power and cutting speed, the cutting force is determined. The surface roughness is measured using Talysurf profilometer by taking average of 3 readings in each region. Then the tool ware is measured by Toolmaker’s optical microscope. We used Response surface method for the determination of the change of outputs with inputs plotting different graphs, contours and 3-D surface plots. We can easily determine the effects by visualizing the main effect plots and interaction plots also. Then using Analysis of variance (ANOVA), the most effective parameter for the output was determined. Then the mathematical model or the regression equation was made taking results from the regression coefficient table. From result, we can see that the most significant factor affecting the cutting force is cutting speed, feed for surface roughness and depth of cut for tool wear.
