| Type of Insert Failure | Cause | Countermeasures |
| Flank Wear | · Grade lacks wear resistance. · Cutting speed is too fast. · Feed rate is far too slow. | · Select a more wear-resistant grade. P30→P20→P10 K20→K10→K01 · Use an insert with a larger rake angle. · Decrease the cutting speed · Increase feed rates. |
| Crater Wear | · Grade lacks crater wear resistance. · Rake angle is too small. · Cutting speed is too fast. · Feed rate and depth of cut are too large. | · Select a more crater-wear-resistant grade. · Use an insert with a larger rake angle. · Change the chipbreaker. · Decrease the cutting speed · Reduce feed rates and depth of cut. |
| Chipping | · Grade lacks toughness. ·Cutting edge breaks off due to chip build-up. · Cutting edge lacks toughness. | · Select a tougher grade. P10→P20→P30 K01→K10→K20 · Increase amount of honing on cutting edge. |
| · Feed rate and depth of cut are too large. | · Reduce rake angle. · Reduce feed rates and depth of cut. |
| Fracture | · Grade lacks toughness. | · Select a tougher grade. P10→P20→P30 |
| · Cutting edge lacks toughness. · Holder lacks toughness. · Feed rate is too fast. · Depth of cut is too large. | K01→K10→K20 ·Select a chipbreaker with a strong cutting edge. ·Select a holder with a larger approach angle. · Select a holder with a larger shank size. · Reduce feed rates and depth of cut. |
| Welding or Built-up Edge | · Inappropriate grade selection. · Dull cutting edge. · Cutting speed is too slow. · Feed rate is too slow. | ·Select a grade with less affinity to the work material like coated carbide or cermet grades. · Select a grade with a smooth coating. · Use an insert with a larger rake angle. · Reduce amount of honing. · Increase cutting speeds. · Increase feed rates. |
| Plastic Deformation | · Grade lacks thermal resistance. · Cutting speed is too fast. · Feed rate is too fast. · Depth of cut is too large. · Not enough cutting fluid. | · Select a more crater-wear-resistant grade. · Use an insert with a larger rake angle. · Decrease the cutting speed · Reduce feed rates and depth of cut. · Supply sufficient amount of coolant. |
| Notch Wear | · Grade lacks wear resistance. | · Select a wear-resistant grade. P30→P20→P10 K20→K10→K01 |
| · Rake anle is too small | · Use an insert with a larer rake anle |
| g . · Cutting speed is too fast. | g g. ·Alter depth of cut to shift the notch location. |
