Abstract
In the present work, the effects of machining factors and cutting fluid flow conditions on tool wear and surface roughness were studied. Response surface methodology technique with Face centered composite design was employed to minimize the number of experiments. The experiments were performed on a hardened AISI D2 rod using mixed ceramic (Al2O3/TiC) inserts in turning process. The effect of machining time was found to be the most influential parameter affecting tool wear, followed by cutting speed. However, machining time followed by feed rate were the most significant parameters on surface roughness. Moreover, cutting fluid condition showed substantial contribution towards decreasing tool wear rate and increasing surface finish.
