Definition
Broaching is a material removal process using a multiple-edged tool whose cutting edges are arranged in a line and with an offset hz (also known as “rise per tooth” (RPT)), which determines the depth of cut per tooth. The tool is moved in one direction only; the feed and width of cut are hereby determined by the tool geometry. The size and shape of the final teeth correspond to the desired geometry of the workpiece. After one single pass of the tool through the workpiece (broaching stroke), the operation is complete, and the workpiece’s surface is finished at the same time. In general, the translational motion is run by the tool at a stationary workpiece (Ostwald and Muñoz 1997; Bralla 2007; Klocke and König 2008; CIRP 2004) (Fig. 1).
