摘要

P In the process and the machine for forming by turning a concave cut (C) in a workpiece (W) on a lathe, the workpiece (W) is supported so that it rotates generally around its longitudinal axis and is rotated in a first direction the piece about an axis corresponding to its longitudinal axis. A cutting tool (28) is rotated about an axis parallel to the axis of rotation of the workpiece in a second direction opposite to the first direction. A tooth on the tool attacks the workpiece to form a concave cut in the workpiece in general. / P
