Which method involves cutting sheet material to size and making a pierced sheet?

The method that involves cutting sheet material to size and making a pierced sheet is blanking and piercing. This process is particularly relevant in manufacturing where sheet metal is cut into specific shapes (blanking) and holes or other features are added (piercing). The two operations often occur in a single die progression, making it efficient for production.

During blanking, the outline of the part is cut from the sheet, resulting in a blank or a piece that will undergo further processing. In the piercing phase, material is removed to create holes or other features as specified in the design. This combination allows for precise shapes and designs while maintaining the integrity of the overall material.

Laser cutting is a highly precise method typically used for cutting intricate designs or shapes but does not inherently involve piercing as part of its primary function. Press forming is a different technique used for shaping materials by using a die to form the sheet material into three-dimensional shapes, and deep drawing involves pulling the sheet into a die to create deeper, more complex shapes rather than just modifying the material's surface.
