Question

Cutting power consumption in turing can be significantly reduced by

• A. Increasing rake angle of the tool
• B. Increasing cutting angle of the tool
• C. Widening the nose radius of the tool
• D. Increasing the clearance angle

Answer 1

The correct option is A Increasing rake angle of the tool

With increase of rake angle, the forces induced during machining will be reduced hence the power consumption reduces but the tool becomes weaker.
