Analysis of Surface Roughness for Turning of Aluminium (6061) Using Regression Analysis

? Surface Roughness and tolerance are among the most critical measures in many mechanical products as competition grows closer customers now have increasingly demanding for high quality; making surface roughness one of the most competitive dimension in today’s manufacturing industries surface of mechanical product can be created with a number of manufacturing process. This works applies the frictional factorial experimentation approach to study the impact of turning parameters on the roughness turned surfaces analysis of variance is used to examine the impact of turning factors and factor interaction on surface roughness.
