LUBRICATION MECHANISMS OF LN2 IN ECOLOGICAL CRYOGENIC MACHINING

Machining Science and Technology, 2006
ABSTRACT Cryogenic machining is considered an environmentally safe alternative to conventional machining where cutting fluid is used. In cryogenic machining, liquid nitrogen (LN2) is well recognized as an effective coolant due to its low temperature, however, its lubrication effect is less well known.

Cryogenic cooling-based sustainable machining

, 2020
Machinability is the most important indicator to measure the performance of any machining operation. Cutting force, surface roughness, tool wear, dimensional accuracy, and cutting temperature, etc. are the most important machinability indicators. Various

Cryogenic Machining of Tantalum

Journal of Manufacturing Processes, 2002
A new approach for the machining of tantalum is presented. The new approach is a combination of traditional turning and cryogenically enhanced machining (CEM). In the tests, CEM was used to reduce the temperature at the cutting tool/workpiece interface, and thus reduce the temperature-dependent tool wear to prolong cutting tool life.

CRYOGENIC MACHINING OF KEVLAR COMPOSITES

Materials and Manufacturing Processes, 1993
ABSTRACT Previous attempts to machine Kevlar aramid fibre reinforced plastics (KFRP) with conventional cutting tools have proven to be extremely difficult. This has somewhat restricted the material's usage, often negating the advantages of its high strength to weight ratio and fatigue tolerance.

Machinability of Hardened Alloy Steel using Cryogenic Machining

Materials Today: Proceedings, 2018
Abstract Machining of hardened alloy steels demand special cutting tools such as PCBN, ceramic. However, these cutting tools are uneconomical and also demand machine tool structures, which have high stiffness and vibration dampening properties. In the current trend towards Green manufacturing it is desired to produce more with less.

Performance of Cryogenic Machining with Nitrogen Gas in Machining of Titanium

Applied Mechanics and Materials, 2011
This research presents performance of nitrogen gas as a coolant in machining titanium. Compressed nitrogen gas stored in a cylindrical tank is supplied to the cutting zone via the stainless steel tube of 2x8x25mm (inside diameter x outside diameter x length) connected to the flexible hose and specially-designed valve with pressure controller.
