Abstract: Grinding fluid, apart from controlling temperature produced at the wheel-work contact zone by way of cooling also helps in lubrication which is achieved by reduction of friction at the wheel-workpiece interface. In the present experimental investigation, grinding fluid is delivered into the grinding zone by a multi-nozzle system in order to determine grindability of low alloy steel at different fluid concentrations. A comparative study has been made among dry and wet grinding using three different coolant concentrations, considering various response parameters, to assess grinding performance at a particular in feed. It is found that high concentration of oil in the fluid produced good results in terms of force requirement and surface roughness.

Keywords: grinding fluids; surface grinding; fluid concentration; multiple nozzles; grinding force; chip formation; grinding ratio; wheel loading; surface roughness; surface quality; grinding performance; low alloy steel; dry grinding; wet grinding; coolants; multi-nozzle systems.
