What is a cutting tool primarily designed to do?

• A. Control the movement of workpieces
• B. Cut metal using one or more edges
• C. Provide power to a lathe
• D. Support the setup of milling machines

Answer: (B)

A cutting tool is primarily designed to cut metal using one or more edges. This is the fundamental function of all cutting tools regardless of their specific application, whether they are used in turning, milling, drilling, or other metal removal processes. The edges of the cutting tool interact with the workpiece material to remove chips and create the desired shape or surface finish. While controlling the movement of workpieces, providing power to machines, and supporting setups are all essential aspects of machining operations, they do not define the primary purpose of a cutting tool. The cutting action, facilitated through sharp edges that shear the metal away, is the key reason cutting tools are engineered in various geometries and materials to achieve effective cutting performance and tool longevity.
