The presence of air around a rotating grinding wheel impedes the effective entry of coolant into grinding zone. Therefore, a proficient method is required to minimize this air boundary before the impingement of fluid-jet into the grinding zone. This paper is an experimental study for finding the better effective method of controlling the air boundary around the wheel. Further, two different techniques of suppressing the air barrier has been studied experimentally and statistically towards improving the cutting fluid action in grinding. Fuzzy models are developed to interpret the relationship between the variables and responses. Experiments are conducted on a horizontal surface grinding machine with the application of scraper board and pneumatic barrier separately behind the flood cooling nozzle. The surface roughness and other mechanical properties of these two methods and traditional flood cooling method are compared. The experimental results specified that the tangential force and the requirement of specific energy are reduced by maximum 25% and 20% respectively by the scraper board (SB) with the comparison to the pneumatic barrier (PnB) method for achieving the equivalent surface quality when tested by positioning them at 60° location from grinding zone. Hence, use of scraper board at close proximity to grinding zone is recommended.
