Cutting is a sheet metal process used to separate metal sheets into specific shapes or sizes. Common cutting techniques include: Laser Cutting，Plasma Cutting，Water Jet Cutting，Mechanical Shearing，Punching and Sawing.

Forming processes involve altering the shape of metal sheets without significantly changing their material thickness to create desired three-dimensional structures. These include: Bending，Stretching，Deep Drawing，Rolling and Curling

Stamping processes involve using a punch press and dies to process metal sheets to achieve complex shapes and functions. These include:Punching,Embossing and Engraving,Flanging

Joining processes involve combining different metal components to form a complete product. Common joining methods include: Welding,Riveting,Threaded Fastening,Adhesive Bonding
