Abstract

The experimental results on investigation on the turning of 7075 aluminium alloy, using
Cryogenic Liquid Nitrogen (LN2) as a coolant was analyzed in this paper. The influence of the
cryogenic LN2 coolant compared with that of the conventional coolant on the cuting performance parameters, such as the cutting force, cutting temperature, andbsurface finish was analysed and investigated. The use of the cryogenic liquid nitrogen coolant influenced the cutting temperature and the cutting force by about 17 to 29% and 11 to 20% reduction respectively. The surface finish value of the machined workpiece is about 15 to 23% better than that of the conventional coolant. Keywords: 7075 aluminium alloy, LN2 cooling, Tool wear, Cutting temperature
