Paper Abstract

A brief description is given of the successful development of a large computer controlled machine for diamond turning aluminium alloy X-ray mirror substrates (1.5 m (60 in.) dia., 600 mm (24 in.) axial length). The in situ metrology facility for axial profile, round-ness and diameter measurement is described, together with the technique for automatic programming of the final tool path to compensate for errors of workpiece deflection, tool setting and edge radius, etc.. Examples are based on the ROSAT and SXT mirrors for which the axial and radial location/mounting surfaces are produced with precise reference to the reflecting surfaces. Adaptation of this type of precision machine/metrology facility to the production of glass ceramic optical components is also discussed.
