Damage of Insert & Counter Measure
| Description | Solution | |
Rapid Flank Wear |
1. Inappropriate feed(f) rate
2. Cutting speed(s) too high |
1. Adjust feed(f) rate according to depth(ap), width(ae)
2. Reduce cutting speed(s) |
Chipping |
1. Feed(f) rate too high 2. Cutting speed(s) too low 3. Vibration of holder & machine |
1. Reduce feed(f) rate 2. Increase cutting speed(s) 3. Reduce the tool overhang & improve the rigidity of machine and workpiece |
Thermal Crack |
1. Insufficient coolant
2. Cutting speed(s) too high |
1. Check cooling system, supply enough coolant or use dry milling
2. Reduce cutting speed(s) |
Build Up Edge |
1. Cutting speed(s) too low 2. Insufficient coolant 3. Not enough rake angle |
1. Increase cutting speed(s) 2. Supply enough coolant 3. Increase rake angle of change inserts |
Notching |
1. Scaling or work hardening in workpiece surface area
2. Burrs in workpiece |
1. Change/Vary cutting condition (feed & depth) 2. Change path or direction |
Fracture |
1. Wrong insert shape or corner radius
2. Corner radius too small 3. Cutting force fluctuation too high |
1. Choose the insert with bigger corner or radius |
Cratering |
1. Insufficient coolant supply
2. Cutting speed(s) and feed(f) rate too high |
1. Increase coolant supply or concentration 2. Reduce cutting speed(s) and feed(f) rate |
Plastic Deformation |
1. Cutting speed(s) too high
2. Too much stress applied on the cutting edge |
1. Reduce cutting speed(s) 2. Supply enough coolant 3. Choose insert with bigger corner radius |
