Cryogenic machining of hard-to-cut materials

Wear, 2000
This paper presents a technique for machining of advanced ceramics with liquid nitrogen (LN2) cooled polycrystalline cubic boron nitride (PCBN) tool, titanium alloys, Inconel alloys, and tantalum with cemented carbide tools. With LN2 cooling, the temperature in the cutting zone is reduced to a lower range, therefore, the hot-strength and hot-hardness ...

Ultra-precision cryogenic machining of viscoelastic polymers

CIRP Annals, 2012
Abstract Microfluidic chips with micro- or nanoscale channels are currently in great demand. PDMS (polydimethylsiloxane), a viscoelastic polymer, has high transparency and good chemical stability, making it a suitable substrate material for such chips.

Sustainable Technology Solution by Cryogenic Machining: Influence of Cryogenic Fluid Phase on Machining Performance

2010
The industry is under increasing pressure of the financial crisis, global competition, stricter environmental legislation and supply-chain demand. To tackle these issues, a sustainable development trend has to be assured synergetically on all the levels/fields, including machining processes. This paper promotes sustainable production via an improvement

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. Machining

Wireless multi-temperature measurement for rotating cryogenic machines

IEEE Transactions on Magnetics, 1992
A method of wireless and multitemperature measurement is proposed, in which the resonant frequency shift of the sensors caused by temperature is the detectable signal. LC resonant circuit sensors consisting of a ferrite yoke coil and a mica-type capacitance were used in the demonstration experiment.
