FLANK ANGLE
Flank angle prevents friction between flank face and workpiece resulting in smooth feed.

Flank angle creates a space between tool and workpiece.

Flank Angle and Flank Wear Relationship

  • Effects of Flank Angle
  1. Increasing flank angle decreases flank wear occurrence.
  2. 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.
