In a punch press, sheet metal is sized or shaped as pressure is applied to a die holding the material.

The resulting configuration depends on the form and construction of the die.

In a punch press, two components work together to create the desired shape. The punch is attached to the ram of the machine. The die is clamped onto a flat bed or anvil perpendicular to the ram. As the machine operates, the punch exerts pressure on the stock material held in the die. Blanking dies produce slugs of sheet metal to make blanks to fit dies for later punch-press operations.

Punch presses range from small manually operated units to large powerful machines operated.

Regardless of the size, however, all punch presses use a die set to complete the punching process.

Male punches and female dies make up a die set. As these pieces come together during the machine cycle, the sheet metal is shaped or cut into the predetermined form. Skilled craftsmen design the die set and set up the machine for production.

Stamping presses also shape or cut metal through a process of deformation with a die. The bottom portion of the die is clamped to the bed or the press, which is essentially a large metal block. The bed remains stationary throughout the machine cycle. The other half of the stamping die is affixed to the ram which moves through an up and down cycle, producing parts from the sheet stock fed through it.
