Abstract
This chapter presents an experimental approach for quantifying the effects of traditional cutting parameters and innovative cryogenic and hybrid cooling methods on specific energy consumption in addition to tool damage and productivity. The chapter also puts forward the application of fuzzy modeling on the experimental data for optimizing the machining process in respect of various combinations of minimizing specific energy consumption and maximizing productivity as well as tool life. The machinability levels of two commonly used industrial alloys, when cut under cryogenic and hybrid environments, have also been comparatively analyzed.
