Methodwise this disclosure relates to the manufacture of workpieces having polygonal inner or outer contours based upon radii of predetermined inner and outer circles with n being the number of angles of the desired polygon, the method including the steps of rotating a workpiece about its axis, moving the tool along an ellipsoidal path while in contact with the rotating workpiece with tool travel along the ellipsoidal path having velocity varying generally sinusoidally as a function of tool location, said ellipsoidal paht is radially offset from the workpiece axis of rotation and its width generally corresponds to the difference between said inner and outer radii, and rotating the workpiece about its axis for a duration of time longer than the duration of movement of the tool along the ellipsoidal path by said factor n.
A method of moving a tool to form a polygonal outline having inner or outer polygonal contours based upon radii of predetermined inner and outer circles with n being the number of angles of the desired polygonal outline comprising the steps of rotating a workpiece to be outlined about a fixed axis, moving a tool along an ellipsoidal path in a plane perpendicular to the workpiece axis while in contact with the rotating workpiece with tool travel along the ellipsoidal path having a velocity varying generally sinusoidally as a function of tool location, said ellipsoidal path is radially offset from the workpiece axis of rotation, and synchronizing the relative rotation of the tool and the workpiece about its axis for a duration of movement of the tool along the ellipsoidal path by said factor n.
Apparatus for moving a tool to form a polygonal outline having inner or outer polygonal contours based upon radii of predetermined inner and outer circles with n being the number of angles of the desired polygonal outline comprising means for rotating a workpiece to be outlined about a fixed axis, means for moving a tool along an ellipsoidal path in a plane perpendicular to the workpiece axis while in contact with the rotating workpiece with tool travel along the ellipsoidal path in a plane perpendicular to the workpiece axis while in contact with the rotating workpiece with tool travel along the ellipsoidal path having a velocity varying generally sinusoidally as a function of tool location, said ellipsoidal path being radially offset from the workpiece axis of rotation, and means for synchronizing the relative rotation of the tool and the workpiece about its axis for a duration of time longer than the duration of movement of the tool along said ellipsoidal by the factor n.
