Sheet Metal Fabrication: An Art

Operations involved in the fabrication of sheet metal are varied and complex. Every step in accomplishing specific tasks and operations also produce chemical and physical changes are defined in the metal.

Every operation is performed according to drawings prepared by engineers and draftsmen based on customer designs and specifications. The operations involved in manufacturing are basically the same and follow the same sequence regardless of the metal that is being fabricated.

The operations involved are:

Shearing – cutting the metal to a specific length and width. The back stop is set by the CNC control to a specific length for each dimension. This operation is the most physically taxing of all operations and may require added equipment like magnets to allow the operator to move the piece.

Punching and Cutting – using punches, dies, and burning to place holes of specific dimensions at specified locations of the flat sheet. This allows the operator to produce more parts in less time. Some parts are so small that they have to be punched by hand on an iron working punch.

Braking – bending the flat metal part at specific places to form a shape defined by the design. The CNC equipment moves the stops to the correct dimension and instructs the operator to use the correct die and punch bar.

Welding – joining metal parts together through electric welding by wire, stick, and other methods.

Sheet metal fabrication is a complex set of operations that produces a part of everything people use in their daily lives. Business is an art form and can produce designs of tremendous beauty and complexity.
