This thesis investigates different wheel-cleaning parameters and configurations such as speed, flowrate, position, and dressing on the creep-feed grinding process. The criterion measured for these experiments was thermal damage to the workpiece and grinding wheel damage.It was determined that one dressing pass was required after experiments with the wheel-cleaning system, while three dressing passes were required for experiments without wheel-cleaning. Moreover, it was found that two grinding passes could be performed with the wheel-cleaning system compared to one without. Additionally, the use of a 120m/s cleaning nozzle can increase the critical specific material removal rate by 100% and decrease specific energy by 33% compared with no wheel cleaning. Furthermore, at the 120m/s speed, there appeared to be a flowrate limit of 15 l/min, above which results changed minimally. Finally, changing the cleaning jet position from normal to closer to tangential had little effect on the results.
