Abstract
Major problem associated while grinding titanium alloy are high specific energy and high grinding zone temperature. To reduce temperature, grinding fluid was used but majority of them was wasted due to formation of stiff air layer around porous grinding wheel rotating at high speed which deflects grinding fluid away from grinding wheel.This paper presents an innovative improvement of MQL process by adding pneumatic nozzle. High compressed air jet from pneumatic nozzle is impinged on grinding wheel surface at an angle of 45° which suppress stiff air layer and clean machined chip, clogged wheel pores from grinding wheel surface. In this work, titanium grade I with alumina grinding wheel is ground at an infeed of 30 μm under flood cooling, MQL and MQL with pneumatic Nozzle conditions. Experimental result shows grindability of titanium grade I alloy under MQL with pneumatic nozzle proves to be an extremely efficient in order to lower grinding force, force ratio, wheel wear, wheel loading and surface roughness.
