Microlens array fabrication on WC mold using EDM milling

EDM milling is considered an excellent method for fabricating complex surfaces on hard materials such as WC molds using simple electrodes [5,6,7]. Though EDM milling is better suited for microlens array mold fabrication than micro-cutting or micro-grinding [ 8 ], significant loss of electrode material occurs and the accuracy of the surface topography is poor.
