FUNCTION OF TOOL FEATURES FOR TURNING

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 relates to flank wear. 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 workpiece.
  • Workpieces suffer from work hardening easily.
