Three Cutting Resistance Forces in Milling

Corner Angle
0°
 Back force is in the minus direction. Lifts the workpiece when workpiece clamp rigidity is low. Corner Angle 0°
Corner Angle
15°
 Corner angle 15° is recommended for face milling of workpieces with low rigidity such as thin workpieces. Corner Angle 15°
Corner Angle
45°
 The largest back force. Bends thin workpieces and lowers cutting accuracy.
* Prevents workpiece edge chipping in cast iron cutting.		 Corner Angle 45°
  • Principal force: Force is in the opposite direction of face milling rotation.
  • Back force: Force that pushes in the axial direction.
  • Feed Force: Force is in the feed direction and is caused by table feed.
