hard turning of AISI 316stainless steel by tungsten carbide inserts (WC). Regression
analysis and ANOVA theory was used to predict surface roughness (Ra) and tool wear (VB).
WC tool inserts performed machining of AISI 316 SS to study main and interaction effects of
processparameters [cutting speed (Vs), feed rate (fs) and depth of cut (ap)]. Adequacies of
developed model were verified by calculationof correlation coefficient (r). These models can …
