High speed end milling of Titanium alloy Ti6Al4V is a potential machining technique for obtaining nano level surface finish using small diameter (2mm and 4mm) tools applying high rpm to facilitate the application of of low values (micro-meter level) of feeda and depth of cut to ensure super finishing that could avoid the need of further grinding and polishing operations. Influences of three cutting parameters, namely cutting speed, axial depth of cut and feed, were analyzed. Mathematical models were developed for output responses Ra and Rt. Analysis of multiple response optimizations of RSM...

Hardened steels, like AISI H13 and D2 extensively as the hot working tools, dies and moulds due to their high hardness and heat resistant properties. However the same properties are responsible for poor machinabilty of these materials. The challenges in machining of these materials in hardened state called for many research works. This book introduces induction heating as a new online heating technique to improve machinability hardened steel AISI H13. The research work considered the influence of heating parameter - temperature; and cutting parameters - cutting speed, feed and axial depth of...
