FUNCTION OF TOOL FEATURES FOR TURNING

END CUTTING EDGE ANGLE
The end cutting edge angle avoids interference between the machined surface and the tool (end cutting edge). 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 for roughing and a large angle in finishing are recommended.
