The ease with which a material can be machined with an acceptable surface finish without damaging the tool is called what?

• A. Machinability
• B. Conductivity
• C. Hardness
• D. Malleability

Answer: (A)

Machinability is the ease with which a material can be machined to produce an acceptable surface finish without excessive tool wear or damage. It captures how the material behaves under cutting, including chip formation, heat generation, and the tendency to dull or wear tools. Factors such as the material’s composition and hardness, cutting speed, feed, depth of cut, tool material and coating, and cooling all influence machinability. The description in the question fits this term exactly because it focuses on achieving a good surface finish while keeping tool wear and damage to a minimum. Conductivity, hardness, and malleability describe other material properties and don’t define the overall ease of machining.
