Which operation is used to remove sharp edges from machined parts?

• A. Deburring
• B. Annealing
• C. Quenching
• D. Forging

Answer: (A)

Removing sharp edges from machined parts is accomplished by deburring. After machining, burrs can form along edges, creating sharp spots that can injure operators, damage other parts, or interfere with proper fits. Deburring sharpens and smooths edges, improving safety, assembly, and surface finish. Methods include mechanical deburring with files or abrasive tools, or other techniques like thermal or chemical deburring, all aimed at removing those excess bits of metal. The other processes—annealing, quenching, and forging—alter material properties or shape but do not specifically remove burrs from edges.
