  • Method and apparatus for micro-machining a surface
    Patent number: 8016644
    Abstract: An apparatus and method for micro-machining a surface of a workpiece having a complex surface profile including desired profile features and finer undesired profile features to be removed, including shaping a formable polishing tool using either the workpiece itself or a replica of the workpiece to have at least said desired profile features, and using said formable polishing tool to micro-machine said surface to remove said finer undesired profile features while maintaining said desired profile features. The formable polishing tool can be shaped to have at least said desired profile features by pressing the formable polishing tool against either the workpiece itself or the replica of the workpiece when the formable polishing tool is in a formable state, and the formable polishing tool can be used for micro-machining when the formable polishing tool is in a solid state.
