Effect of process parameters on material removal rate during grinding of hot work steel AISI H11 under dry, wet and compressed gas environment

Abstract

Grinding can be described as a multi-tooth metal cutting operation in which material is generally removed by shearing and ploughing in the form of micro sized chips by the abrasive grits of the grinding wheel. This paper presents an important investigation of material removal behaviour during grinding of hot work steel AISI H11 under different working environments (dry, wet cooling and compressed gas) and process parameters ( feed rate, depth of cut and wheel speed). During the experimental investigation, Aluminimum oxide grinding wheel was used to perform cutting action. It was observed that under compressed gas, increase in depth of cut and decrease in feed rate resulted in significant increase in material removal rate.
