Which metal wasting process uses a press to cut shapes or holes in sheet metal?

• A. Milling
• B. Turning
• C. Punching and stamping
• D. Laser cutting

Answer: (C)

Punching and stamping use a press to cut shapes or holes in sheet metal. In this process, a punch drives through the metal and into a matching die, shearing out the desired shape in a single stroke. It’s highly efficient for making many identical holes, slots, or cutouts, and stamping can also form features by shaping the metal as it’s pressed. This reliance on a punch and die set, powered by a press, is what differentiates it from other methods. Milling and turning remove material with rotating cutting tools on machine tools, while laser cutting uses a focused beam to cut without a punching action.
