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 end cutting edge angle increases cutting edge strength, but it also increases cutting edge temperature.
2. Decreasing end cutting edge angle increases 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.
