Economical and Ecological Cryogenic Machining
Journal of Manufacturing Science and Engineering, 1999To eliminate health and environmental problems caused by using conventional cutting fluid in the machining industry, a new economical and practical approach to cryogenic machining technology was developed. Using micro nozzle jetting to the cutting point locally, this approach minimizes the amount of liquid consumption to levels at which nitrogen costs ...

Cryogenic machining of hard-to-cut materials
Wear, 2000This 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 ...

Machinability of the EBM Ti6Al4V in Cryogenic Turning
Key Engineering Materials, 2015In machining operations, the adoption of a cutting fluid is necessary to mitigate the effects of the high temperatures generated on the cutting zone, and, therefore, to avoid severe detrimental effects on the tool wear and surface integrity. In the biomedical field, the traditional processes to manufacture surgical implants made of Titanium and Cobalt ...

The Development of New Turning Tool for Cryogenic Machining
Volume 2: Manufacturing Processes; Manufacturing Systems; Nano/Micro/Meso Manufacturing; Quality and Reliability, 2020Abstract Cryogenic manufacturing processes have emerged as environmental-friendly, increase tool life and improve surface integrity of machined components by efficiently removing the heat from the cutting zone. Especially considered to be an efficient method to machine difficult-to-cut metals which are poor thermal conductivity, such as ...

A cryogenic dose calorimeter for pulsed radiographic machines
AIP Conference Proceedings, 1995Calorimetry is the most direct, absolute technique for absorbed dose measurements. To improve the measurement accuracy for use with quantitative radiography, a calorimeter has been developed for LANL’s pulsed radiographic machines which produce bremsstrahlung radiation fields of 50–200 Rad per pulse at 1 meter from the source.
