Turn-milling is a machining method for the efficient forming of complex axisymmetric workpieces on turning centres using a milling cutter. In turn-milling, the primary (rotary) motion is performed simultaneously by the cutter and the workpiece, while the feed motion is usually performed by the cutter.
