END CUTTING EDGE ANGLE

 

End cutting edge angle prevents wear on tool and workpiece surface and is usually 5°― 15°.

Effects of End Cutting Edge Angle

1. Decreasing the end cutting edge angle increases cutting edge strength, but it also increases cutting edge temperature.
2. Decreasing the end cutting edge angle increases the back force and can result in chattering and vibration while machining.
3. Small end cutting edge angle in roughing and large angle in finishing are recommended.
