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 Insert||Trouble shooting|
|Insert Fracture||To avoid insert fracture we should select |
thicker insert,tougher grade and stronger
You should reduce depth of cut and feed rate.
|Edge chipping||We should select tougher grade and stronger chip breaker.|
Cutting speed- Increase
Feed rate- Reduce
|Notch wear||Cutting speed- Reduce|
Tool- Smaller setting angle.
|Comb cracks||Cutting speed- Reduce|
Coolant flow- abundant flow/shut off coolant
|Plastic deformation||Coolant- Use|
|Flank wear||Cutting speed- reduce|
|Crater wear||Coolant- use|
Cutting speed- Reduce
|Cutting edge build up||Cutting speed- Increase|
Coolant- Without Coolant
|Chip Hammering||Feed rate- Change|
Depth of cut- Change
Tool holder- Different setting angle
