Slotting is a machining process that involves the subtractive manufacturing of flat and curved workpieces using a cutting tool (slotting tool). In the slotting process, there is a primary rectilinear motion in the vertical plane and an intermittent (stepped) rectilinear or curvilinear feed motion.
The slotting process is also used in the peripheral subtractive manufacturing of gears using:
- Maag method – a shaped slotting tool is used, which allows partial cutting of several teeth;
- Fellows method – a gear-shaped slotting tool is used, which forms a gearbox with the workpiece.
