A turning operation in which a single-point tool moves radially, along the end of the workpiece, removing a thin layer of material to provide a smooth flat surface. The cutting tool moves from the outer diameter to the center or inner diameter of the workpiece or can move in the opposite direction. The depth of the face, typically very small, may be machined in a single pass or may be reached by machining at a smaller axial depth of cut and making multiple passes. For a finish operation, the cutting feed is calculated based on the desired surface roughness and the tool nose radius.
