Which CNC machine uses force to create bends or holes in sheet metal?

• A. CNC Punch Press
• B. Laser Cutter
• C. Water Jet
• D. Drill Press

Answer: (A)

Think about how each machine actually shapes the metal. A CNC punch press works by pushing a punch through the sheet into a die, applying a high, concentrated mechanical force to shear or form the metal. This is the classic punching and forming action used to create holes and other features quickly on sheet metal. In contrast, a laser cutter uses a focused laser beam to melt or vaporize material along a cut line, which is an energy-based method rather than a physical punching force. A water jet relies on a high-pressure water jet (often with abrasive) to erode material, also not a punching action. A drill press uses a rotating drill bit to cut holes, which is a cutting process via rotation rather than the punching/forming action of a punch and die. So the machine that uses force to create bends or holes in sheet metal is the CNC punch press.
