Home > Metal Fabricating Tips & Facts > Notching Process


Notching is a shearing process during which a metal scrap piece is removed from the outside edge of a metal workpiece. Notching is typically a manually operated, low-production process.

During a notching operation, the metal workpiece has an outside edge removed by the use of multiple shear blades that are set at right angles to each other.

Characteristics of the notching process include:

  • Only removes metal from the outside of a workpiece
  • Is capable of making different angle notches (accomplished by adjusting the location of the workpiece)
  • Produces cuts not possible when using the shearing process
  • Can be used as a process to facilitate later roll forming or stamping processes

The illustration that follows provides a two-dimensional look at a typical notching process. Note how the tool removes the notched part.

As mentioned above, the notching process removes materials from the outside edge only of the workpiece.

The illustration that follows shows how a metal workpiece may look after the notching process is employed and has removed material from the outside edges.

The tooling used in the notching process normally has only two blades, set at 90° angles to each other. The illustration that follows shows what a common notching tool might look like.
