Surface Integrity of machined surfaces is defined based on various constituents e.g. surface roughness, microstructure, surface hardening and microhardness, which all are influenced by machining parameters such as coolant, cutting speed, tool wear, feed, depth of cut and tool material and its geometry. An effort has been made in this book to study the effect of slab down milling process parameters on surface integrity of HSLA (ASTM A572 Grade 50). Experiments were performed as per Taguchi L18 orthogonal array for different combinations of machining parameters to collect data which were...
