Shaping as a cutting process with a single-edged tool is effected in the interrupted cut by utilizing the working stroke. When the tool is being returned (return stroke), no chips are removed.
Shaping is closely related to the technique of planing. The differences exist in the cutting and feed movement. In the case of shaping the tool performs the cutting movement and the workpiece performs the feed movement.

The technique of shaping can be performed as shaping or slotting.
During shaping normally big amounts of material are removed by straight-lined cutting and feed movements. Prefabricated prismatic and rotationally symmetrical workpieces are machined. As with shaping a maximum surface finish of Rz = 10 µm can be reached, subsequent techniques such as grinding and scraping are applied.
