In machine tool apparatus non-circular profiles are cut on workpieces by rotating the workpiece about its axis and locating a cutting tool and toolholder for displacement parallel to and radially of said axis during cutting. Movement of the tool in the radial direction is according to the angular position of the workpiece about the axis of rotation. Such radial movement may be achieved by a cam and camfollower arrangement, the cam drive being controlled according to the position of the workpiece about its axis. |
