What is the process called to remove sharp edges from a cut workpiece?

• A. Deburr
• B. Polish
• C. Grind
• D. Sand

Answer: (A)

Deburring is the process of removing sharp edges left after cutting. When a part is cut, tiny burrs or sharp protrusions often form along the edges. Deburring targets those burrs to make the edge safe to handle, prevent injury, and ensure a proper fit with other components. It can be done with a deburring tool, a file, or by creating a small bevel (chamfer) to smooth the edge. After this step, other finishing actions like polishing can be used if a smoother surface is needed, but deburring specifically addresses getting rid of the sharp edge itself.
