Rake angle is a critical parameter in machining that influences the cutting efficiency, tool life, and surface finish of the workpiece. It determines the direction of chip flow and affects the force required for cutting, with positive rake angles generally reducing cutting forces and improving surface quality.

Rake Angle

Cutting efficiency refers to the effectiveness with which a cutting tool or process removes material while minimizing waste, energy consumption, and wear on the tool. It is crucial for optimizing production costs and ensuring high-quality finishes in manufacturing operations.

Cutting Efficiency

Tool life refers to the duration a cutting tool can effectively perform its function before it needs to be replaced due to wear or failure. It is a critical factor in manufacturing efficiency, impacting production costs, machine downtime, and product quality.

Tool Life

Surface finish refers to the texture and smoothness of a surface, which can significantly impact the functionality and aesthetics of a product. It is crucial in manufacturing processes as it affects properties like friction, wear resistance, and the ability to form a proper seal or bond with other materials.
