Journal ArticleDOI
TL;DR: In this paper, the effect of various cutting fluid levels and cutting parameters on surface roughness and tool wear was studied, and the results showed that the optimum level of cutting conditions for desired surface roughnesses were at a high level of low flow high-velocity (LFHV) cutting fluid flow from the selected levels.

Journal ArticleDOI
TL;DR: In this article , a series of novel itaconic acid (IA) based epoxy vitrimers incorporated dynamic β-hydroxy ester bonds and boronic ester bond were successful fabricated using IA derivate with double terminal epoxy and 2,2'-(1,4-phenylene)bis[5-methyl-1,3,2-dioxaborinane-5-carboxylic acid] (BDCB) with two carboxyl groups by a reaction between epoxy, and the obtained IA-based epoxide vitrimer possesses comparable thermal stability (T5d = 255 °C) and mechanical properties (tensile strength = 68.3 MPa), elongation at break = 16.2 MPa).

Journal ArticleDOI
TL;DR: A review of the important research papers published regarding the MQL-based application of mineral oils, vegetable oils and nanofluid-based cutting fluids for different machining processes, such as, drilling, turning, milling and grinding, etc..

349 citations

Journal ArticleDOI
TL;DR: In this article, a high-temperature nickel-based alloy GH4169 was used as workpiece to evaluate the lubrication performance at the grinding wheel/workpiece interface, and the mechanism of lubrication was also studied based on the molecular structure of vegetable oil.

322 citations

Journal ArticleDOI
TL;DR: In this paper, seven typical vegetable oils (i.e., soybean, peanut, maize, rapeseed, palm, castor, and sunflower oil) were used as the minimum quantity lubrication (MQL) base oil to conduct an experimental evaluation of the friction properties of the grinding wheel/workpiece interface.

278 citations

Journal ArticleDOI
TL;DR: In this paper, a comprehensive analysis of literature pertaining to ecological trends in machining processes of difficult-to-cut materials (e.g. hard steels, Ti-based alloys, Ni based alloys) has been performed.

Journal ArticleDOI
TL;DR: This paper is a thorough review of all the modern sustainable techniques presently practiced in the metal cutting process and finds that these sustainable machining techniques most of the time give better results in terms of improved surface quality of the machined component, enhanced tool life, less cutting temperatures and cutting forces as compared to conventional wet machining methods.
