Investigation of tool wear and cutting force in cryogenic machining using design of experiments

Current work involved experimental study of the effect of cryogenic cooling on tool wear and high frequency dynamic cutting forces generated during high speed machining of stainless steel. Experiments were carried out both in dry and cryogenic conditions as per design of experiments to understand the relative advantage offered by cryogenic cooling. It was found from the experimental results that cryogenic cooling was effective in bringing down the cutting temperatures that attributed for the substantial reduction of the flank wear (37.39%). Such input parameters as speed, feed and depth of cut were correlated with output parameters, namely cutting force and flank wear through a regression equation. It was concluded from the present work that, cryogenic cooling is a possible answer for high speed eco-friendly machining. (C) 2007 Elsevier B.V. All rights reserved.
