Abstract
A method of generating an aspheric surface (2) on a workpiece (1) which method comprises rotating the workpiece (1) about an axis (AA) coinciding with the required axis of symmetry of the surface (2) to be formed and applying to the workpiece (1) an annular tool (3) rotating about the axis (BB) of its annular cutting edge (4), the relative positions of the intersection of the tool and workpiece axes (BB and AA) and the intersection of the workpiece axis (AA) and tool plane in a plane common to the workpiece and tool axes being continuously variable with respect to one another in a predetermined controlled relationship whilst the tool (3) and workpiece (2) are maintained coplanar in the plane of relative movement of the said intersections. <IMAGE>
