THE ONSET OF THERMAL DAMAGE, WHICH MAY BE INDUCED BY THE GRINDING PROCESS AT HIGH REMOVAL RATES, CONFLICTS DIRECTLY WITH THE DEMAND FOR INCREASED PRODUCTION EFFICIENCY. TO PREDICT THE THERMAL DAMAGE THRESHOLD, THE ENERGY PARTITIONING TO THE WORKPIECE NEEDS TO BE DETERMINED. IT IS NOT PRACTICABLE TO MEASURE DIRECTLY THE HEAT INPUT INTO THE WORKPIECE OR ENERGY PARTITIONING TO THE VARIOUS HEAT SINKS WITHIN THE GRINDING ZONE. HEAT TRANSFER MODELS ARE THEREFORE EMPLOYED TO EVALUATE THE ENERGY PARTITIONING ANALYTICALLY. THIS PAPER PRESENTS ALTERNATIVE THERMAL MODELS THAT WERE DEVELOPED BY EMPLOYING DIFFERENT ENERGY PARTITIONING ASSUMPTIONS. THE EFFECTS OF EACH MODEL ON THE PREDICTED CRITICAL VALUES OF TEMPERATURE AND SPECIFIC ENERGY WERE INVESTIGATED.
