Abstract

In the ever prospering manufacturing sector, titanium is considered as an important material due to its mechanical properties, but grinding of titanium is quite a challenging task that needs necessary attention in order to improve its grindability. Past research works reported the success of sub-zero degree cooling for enhancing grindability of several materials. The present experimental work explores the effect of application of environment friendly liquid CO 2 during grinding of titanium grade I alloy compared to that under dry condition. Grindability of silicon carbide and alumina wheel is investigated and compared. Experimental results indicate that alumina wheel performs better with liquid CO 2 than SiC wheel and that in dry condition while grinding titanium grade I. Therefore, liquid CO 2 based cooling system may be used in industry with alumina wheel when grinding titanium grade I.
