Broaching is performed using a multiple-teeth cutting tool by moving the tool linearly relative to the work in the direction of the tool axis.
The machine tool is called a broaching machine, and the cutting tool is called a broach.
There are two principal types of broaching:
- external broaching (also called surface broaching)
- internal broaching
External broaching is performed on the outside surface of thework to create a certain cross-sectional shape on the surface
Internal broaching is accomplished on the internal surface of a hole in the part.
