Bonnet tool polishing, combined traditional optical polishing technique with modern NC technology, is an novel optical polishing technique. As the motion control and material removal process is different from metal cutting NC machine tool, the NC programming for bonnet tool polishing NC machine tools cannot be carried out with commercial CAM software. This paper analyses the kinematics of feed mechanism and precession mechanism using coordinate transformation method and sets up the feed and precession kinematics equations. The arithmetic of post processing applied to NC automatic programming system is proposed according to kinematics equations and detail bonnet tool polishing technique.

Optical Polishing

In the framework of an assessment of optical polishing techniques, ESA has signed a contract with Media Lario to deliver two 250 mm mirrors with a common optical design to be polished down to very tight surface requirements. NOPT mirrors are respectively made of Zerodur and AlSi alloy with electroless nickel and will they be polished by means of bonnet polishing. Mirrors are light-weighted up to 20kg/m2; the mechanical and optical design is proven to be scalable up to 1m CA surfaces. This paper reviews the mirrors opto-mechanical design, introduce the polishing and metrology strategy while highlighting the differences and the common point in fabricating such mirror in Zerodur and metal.
