Development of a new cooling approach and the performance evaluation of cryogenic liquid nitrogen as a coolant in the turning process

Abstract

Chip form and cutting tool wear are two important aspects newlinecommonly considered in evaluating the performance of a machining process newlineMachining industries essentially aim for a high metal removal rate and better newlineproduct quality Major problems in achieving high productivity and quality newlineare caused by the high cutting temperature developed during machining The newlinehigh cutting temperature in machining causes dimensional deviation and newlinepremature failure of the cutting tools It also impairs the surface integrity of newlinethe product by inducing residual stresses surface and subsurface micro cracks newlinein addition to rapid oxidation and corrosion newline newline newline
