Ow. Fahnle et al., DETERMINATION OF THE OPTIMUM STARTING SURFACE FOR THE GENERATION OF ASPHERICAL SURFACES OF REVOLUTION, Applied optics, 36(34), 1997, pp. 9112-9114
We present a method to obtain the optimum surface shape for use as a s
tarting point for the machining of aspherical surfaces of revolution.
Applying this method, the volume that remains to be machined away can
be set below an acceptable value. Subsequently, it is shown how this m
ethod can be applied for conic surfaces.
