Type of Wear
×
Flank Wear
Flank Wear
Cause
High cutting speed
Low wear resistance carbide grade
Remedy
Reduce cutting speed
Use harder grade
Increase coolant pressure
Adjust center height position
×
Crater Wear
Crater Wear
Cause
Excessive cutting temperatures and pressures on the top of the insert.
Remedy
Reduce cutting speed
Reduce feed rate
Use harder grade
Increase coolant pressure
Use an insert with a positive cutting rake
×
Plastic Deformation
Plastic Deformation
Cause
Cutting temperature is too high
Remedy
Reduce cutting speed
Reduce feed rate
Use harder grade
Increase coolant pressure
×
Notch Wear
Notch Wear
Cause
Cutting speed too high, or insufficient insert wear resistance of the carbide grade
Remedy
Reduce the cutting speed
Reduce the feed rate
Use harder grade
Vary the cutting depth
Increase coolant pressure
×
Thermal Cracking
Thermal Cracking
Cause
Excessive variations in surface temperature, intermittent machining, or variations in coolant supply
Remedy
Reduce cutting speed
Reduce feed rate
Use tougher grade
Use stronger edge geometry
Turn off coolant supply when machining interrupted cuts
×
Edge Fracture
Edge Fracture
Cause
Caused by excessive insert wear before indexing the insert
The grade and geometry could be too weak for the applications
Excessive load on the insert
Built-up edge has been formed on the insert
Remedy
Reduce the cutting speed
Use tougher grade
Reduce the feed rate
Use more stable tool holder
Use reinforced cutting edge negative cutting rake
Use screw clamping instead of self clamping
Adjust center height position
Reduce tool extension
×
Built-up Edge
Built-up Edge
Cause
Cutting zone temperature is too low
Negative cutting geometry
Machining of very sticky materials such as low-carbon steel, stainless steels, and aluminum
Remedy
Increase the cutting speed
Use an indexable insert with a sharper cutting edge
Increase the coolant pressure
×
