Proposed in this paper is a new method for axisymmetric form generation. The equipments required is a face grinding machine with two spindles configured as one grinding wheel to face another for workpiece. The infeed grinding is applied at the position of the wheel half overlapped against the workpiece. When the axes of two spindles are set to be parallel. The forms are in axisymmetric thee-dimension. By taking account of the extra effects of cutting path density, it is further able to give a variation in concave or convex profiles of corn, spherical or ellipse shapes. This new method receives no effect of tool wear, therefore, is effective in form generation for large diameter optical components. The newly proposed method has been applied to φ200mm optical glass in this research to produce a convex lens.
