Crater wear 1. Chipping, fracture 2. Flaking 5. Initial chipping 3. Flank wear Solution Problem Cause Grade Cutting conditions / other 1. Chipping, fracture • Excessive vibration • Use a tough grade • Reduce the feed rate or impact • Eliminate the vibration • Torn away built-up edge 2. Flaking • Excessive vibration • Use a tough grade • Reduce the feed rate or impact • Eliminate the vibration 3. Flank wear • Cutting speed too high • Use a grade with high • Reduce the cutting speed • Inadequate tool toughness wear resistance • Reduce the feed rate • Use a coated grade • Use coolant properly 4. Crater wear • Cutting speed too high • Use a grade with high • Reduce the cutting speed • Feed rate too high wear resistance • Reduce the feed rate • Inadequate tool toughness • Use a coated grade • Use coolant properly 5. Initial chipping • Inappropriate guide • Use a tough grade • Adjust or change the guide bush or pilot hole bushing or pilot hole • Misalignment • Reduce the feed rate • Correct the misalignment 196 ISCAR
