In recent years, hard turning has emerged as a burgeoning cutting technology for producing high-quality finishing of cylindrical-shaped hardened steel variety industrial applications. Hard under dry was not accepted because the generation higher temperatures which accelerated tool wear and produced an inferior surface finish. Nowadays, minimum quantity lubrication (MQL) is widely in to reduce p...

Poor surface finish on die and mould transfers the bad quality to processed parts. High roughness is an example of that normally reduced by manual polishing after conventional milling machining process. Therefore, in order avoid disadvantages disadvantage machining, a sequence two operations proposed. The main operation run followed Rotary Ultrasonic Machining Assisted Milling (RUMAM). However,...
