发明名称 ASYMMETRISCHER WÜRFELECKIGER GEGENSTAND UND HERSTELLUNGSVERFAHREN
摘要 A method is disclosed for manufacturing a cube corner article comprising the steps of providing a machinable substrate material suitable for forming reflective surfaces, and creating a plurality of geometric structures including cube corner elements in the substrate. The step of creating the cube corner elements comprises directly machining at least three sets of parallel grooves in the substrate so that only one side of at least one groove in at least one groove set forms cube corner element optical surfaces.
