Tool wear types.CNC troubleshooting for turning tool.Tool wear and tool life.
What is tool wear?

Breakage or too short tool life.

To reduce breakage and reduce short tool life ,we need to reduce cutting data.

Reduce Feed rate & reduce cutting depth.

Wear Pattern on the insert.

Wear pattern on the InsertTrouble shooting
Insert FractureTo avoid insert fracture we should select
thicker insert,tougher grade and stronger
chip breaker.
You should reduce depth of cut and feed rate.
Edge chippingWe should select tougher grade and stronger chip breaker.
