troubleshooting indexable insert drilling

wear to open space
wear to open space is the preferred type of wear, if it is even.
problem
 cutting speed too high
 oil content in coolant too low
 too little cooling
 concentricity error
countermeasures
 lower cutting speed
 increase oil content in coolant
 increase coolant quantity
 check concentricity
plastic deformation
problem
 cutting speed too high
 feed rate too high
 too little cooling
countermeasure
 reduce cutting speed
 reduce feed rate
 increase cooling
breakouts
problem
 tip angles do not match
 unstable conditions
 concentricity error
 feed rate too high
 too little cooling
countermeasure
 check tip angle
 check clamping
 check concentricity
 reduce feed rate
 increase cooling
built-up edge
problem
 cutting speed too high/too low
 oil content of coolant too low
countermeasure
 increase cutting speed so that the built-up edge moves to the centre
 decrease cutting speed so that the built-up edge moves to the outer edge or is avoided
 increase coolant oil content
