Abstract:


Many industries are using difficult-to-cut materials; therefore it is necessary to improve the
productivity of products from these materials without compromising the quality with reduced
environmental impact and cost. Machining of these materials is usually associated with high
machining costs and low productivity. This is due to the excessive generation of heat at the
cutting zone and difficulties in heat dissipation due to relatively low heat conductivity of these
materials. Nowadays, metal cutting industries are looking towards new sustainable machining
methods to reach the target set by the environmentally conscious regulations in terms of usage
and disposal of chemical contaminant conventional coolants without sacrificing the productivity.
Few of such sustainable machining methods are using minimum quality lubrication and
cryogenic cooling while machining. The portability of the setup for these techniques for
commercial use will be discussed. Experimental results and observations while machining
17-4 PH SS while machining under cryogenic (liquid nitrogen), Minimum quality lubrication,
wet and dry environments will be discussed. Methods for effective usage of liquid nitrogen
while machining by modifying tool holder will be discussed.
