Nanocoining is a new process that could be used to mass produce large areas of nanostructured coatings economically. A diamond die was attached to a 1 KHz actuator which had an elliptical path that matched the die's velocity with the mold velocity. Equations were developed to define the shape of the elliptical tool-path and the actuator was calibrated to produce this shape. Alignment techniques were used to make the die parallel to the mold by rotating the die about two axes of rotation to within 0.01°. The indented nickel mold and replicates created using a UV curable epoxy were examined in an SEM and AFM and the results showed the mold was able to successfully transfer features to replicates. A 250 nm sub-wavelength indenter was used to produce features which could be suitable for anti-reflective applications. An experiment has been performed to nanocoin features onto the outside surface of a rotating cylinder to mimic an industrial manufacturing process and produce a mold which could test the roll transfer production of nanofeatures.
