Journal ArticleDOI
Ecological trends in machining as a key factor in sustainable production – A review
Grzegorz Królczyk,Radoslaw W. Maruda,Jolanta B. Krolczyk,Szymon Wojciechowski,Mozammel Mia,Piotr Niesłony,Grzegorz Budzik +6 more
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
An approach to cleaner production for machining hardened steel using different cooling-lubrication conditions
TL;DR: In this article, the effect of three sustainable techniques, along with the traditional flood cooling system, on prominent machining indices such as cutting temperature, surface roughness, chip characteristics and tool wear in plain turning of hardened AISI 1060 steel has been investigated.
Journal ArticleDOI
A study on droplets sizes, their distribution and heat exchange for minimum quantity cooling lubrication (MQCL)
Radoslaw W. Maruda,Grzegorz Królczyk,Eugene Feldshtein,Franci Pušavec,Michał Szydłowski,Stanisław Legutko,Agnieszka Sobczak-Kupiec +6 more
TL;DR: In this paper, the influence of emulsion mist formation parameters and the nozzle distance from the tool-chip interface, on the droplet velocity at the nozzle outlet, on active medium atomization angle as well as on the diameter and number of droplets supplied to the cutting zone was analyzed.
Journal ArticleDOI
Eco-Friendly Cutting Fluids in Minimum Quantity Lubrication Assisted Machining: A Review on the Perception of Sustainable Manufacturing
Binayak Sen,Mozammel Mia,Mozammel Mia,Grzegorz Królczyk,Uttam Kumar Mandal,Sankar Prasad Mondal +5 more
TL;DR: In this paper, the authors present a summary of the previously published research articles on minimum quantity lubrication (MQL) assisted machining and explore the benefits of the vegetable oil and nanofluid as a lubricant.
Journal ArticleDOI
Multi-objective optimization and life cycle assessment of eco-friendly cryogenic N2 assisted turning of Ti-6Al-4V
Mozammel Mia,Munish Kumar Gupta,Jose Adolfo Lozano,Diego Carou,Danil Yu. Pimenov,Grzegorz Królczyk,Aqib Mashood Khan,Nikhil Ranjan Dhar +7 more
TL;DR: In this paper, the cutting force, specific energy, temperature, surface quality (i.e. surface roughness), and material removal rate under the impingement of liquid nitrogen (LN2) as mono-jet and dual-jets were investigated.
