An update on diamond machinable materials is presented with emphasis on A201 cast aluminum and electroless nickel plating. Surface figure is discussed for spherical and aspherical surfaces, including base radius tolerances, irregularity, clear aperture and slope. A review of recent work on surface finish and scatter is summarized. Current machine tool capabilities are presented with considerations for post polish, where machine produced accuracies do not suffice.
