The finish symbol 'C' represents which operation?

• A. Chipping
• B. Grinding
• C. Machining
• D. Cutting

Answer: (A)

Finish symbols on drawings tell you which finishing step to apply to a part. The symbol C corresponds to chipping, the manual removal of excess material such as flash, burrs, or rough edges after forming. It’s a rough cleanup step aimed at getting the piece closer to shape rather than producing a precise dimension or a fine surface. Machining, cutting, and grinding are other types of operations with different implications: machining and cutting cover broader material removal and shaping, while grinding is used for fine, precise finishing. So the C symbol specifically signals chipping as the finishing action.
