CORNER ANGLE (CH) AND CUTTING CHARACTERISTICS
Cutting Resistance Comparison Between
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 0
Corner Angle
45°
 The largest back force.
Bends thin workpieces and lowers cutting accuracy.
*Prevents workpiece edge chipping when cast iron cutting.		 Corner Angle 0
*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.
