FUNCTION OF TOOL FEATURES FOR TURNING
FLANK ANGLE
Flank angle prevents friction between flank face and workpiece resulting in smooth feed.
Effects of Flank Angle
- Increasing flank angle decreases flank wear occurrence.
- Increasing flank angle lowers cutting edge strength.
When to Decrease Flank Angle |
- Hard workpieces.
- When cutting edge strength is required.
|
When to Increase Flank Angle |
- Soft workpieces.
- Workpieces suffer from work hardening easily.
