Advanced Turning

Causes

- Insert grade too soft

- High cutting speed

- Feed rate too low

Solutions

- Choose a highly wear-resistant grade

- Decrease cutting speed

- Increase feed moderately

Causes

- Poor insert tolerance

- Large cutting resistance and cutting edge flank

Solutions

- Increase insert tolerance

- Choose a sharper breaker

- Decrease the nose radius

- Decrease the side cutting edge angle

- Improve holder rigidity

Causes

- Welding occurs

- Improper cutting edge geometry

- Vibration occurs

Solutions

- Increase cutting speed

- Change to wet cutting or use water-insoluble coolant

- Choose a sharp breaker

- Increase nose radius

- When vibration occurs, lower the cutting conditions

- Improve holder rigidity
