This paper outlined the factorial design methodology, which is applied to improve the surface roughness in turning operation by optimizing the turning parameters. Researchers were interested in investigating the effect of cutting parameters (feed rate, spindle speed, depth of cut), tool geometry parameters (tool nose radius, tool rake angle), and coolant condition in a single experiment using a fractional...
This paper optimizes multiple characteristics (surface roughness and tool wear) in turning of EN-31 steel using tungsten carbide inserts. Five controllable factors of the turning process viz. cutting velocity, feed rate, depth of cut, tool nose radius and different concentrations of solid-liquid lubricants, were studied. A factorial composite design (25 + 8) was used for experimentation. Response...
