Mechanical cutting methods use direct force to cut through sheet metal without heat. Shearing is used for long straight cuts, punching creates holes or shapes using dies, and sawing is used for larger cuts. These methods are ideal for mass production, especially where speed and cost-effectiveness are priorities over intricate detailing.

Mechanical Cutting (Shearing, Punching, Sawing)
Mechanical cutting methods use direct force to cut through sheet metal without heat. Shearing is used for long straight cuts, punching creates holes or shapes using dies, and sawing is used for larger cuts. These methods are ideal for mass production, especially where speed and cost-effectiveness are priorities over intricate detailing.
