This study considers the comparison between the surface roughness criteria (Ra, Rz and Rt)
of the wiper inserts with conventional inserts during hard turning of AISI 4140 hardened steel …

The use of cryogenic coolant in metal cutting has received renewed recent attention
because liquid nitrogen is a safe, clean, non-toxic coolant that requires no expensive …

This research work concerns the elaboration of a surface roughness model in the case of
hard turning by exploiting the response surface methodology (RSM). The main input …

Hard turning with multilayer coated carbide tool has several benefits over grinding process
such as, reduction of processing costs, increased productivities and improved material …

The present contribution deals with the study of the effects of cutting speed, feed rate and
depth of cut on the performance of machining which traditionally named “machinability”. The …

A comparative study is undertaken in terms of the surface roughness criterion (Ra), the
tangential cutting force (Fz), the cutting power (Pc), and the material removal rate (MRR) in …

Background Now-a-days, newer hardened steel materials are coming rapidly into the market
due to its wide applications in various fields of engineering. So the machinability …

In this study, an attempt has been made to statistically model the relationship between
cutting parameters (speed, feed rate and depth of cut), cutting force components (Fx, Fy and …

The development in the manufacturing flied requires the continuous optimization using
various methods. In order to minimize some technological output (such as surface …

Large quantities of coolant–lubricants are still widely used in the metal working industry,
generating high consumption and discard costs and impacting the environment. This paper …
