FUNCTION OF TOOL FEATURES FOR TURNING
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
- Decreasing the end cutting edge angle increases cutting edge strength, but it also increases cutting edge temperature.
- Decreasing the end cutting edge angle increases the back force and can result in chattering and vibration while machining.
- Small end cutting edge angle in roughing and large angle in finishing are recommended.
