Land Wear
           Cause
         •  Cutting temperature is too high
           Remedy
         •  Check cutting parameters
         •  Reduce cutting feed
         •  Increase coolant pressure/volume
         •  Use harder grade
         •  Check that the correct geometry is used



           Crater Wear
           Cause
         •  Excessive cutting temperatures and
           pressures on the top of the insert
           Remedy
         •  Reduce cutting feed
         •  Check that the correct geometry is used



           Thermal Cracking

           Cause
         •  Excessive variations in surface
           temperature, intermittent machining,
           or variations in coolant supply
           Remedy
         •  Increase coolant pressure/volume
         •  Increase oil concentration percentage


           Flank Wear

           Cause
         •  High cutting speed
         •  Low wear resistance Carbide grade
           Remedy
         •  Check that the correct geometry is used
         •  Increase coolant pressure
         •  Change to harder grade
         •  Increase oil concentration percentage
         •  Reduce cutting speed and increase feed
