    Abstract

    This paper discusses a new micro milling strategy for manufacturing optical functionality on steel. The micro-structures, a combination of arrays of micro-ridges, has been developed to achieve the function. The function is to maximize the contrast of the reflected light from orthogonally patterned features. The burr formation and insufficient material removal, influenced by the tool wear and the machine accuracy, were the main challenges in this process. The cutting strategy was investigated in order to reduce the burr formation during the process. By the new strategy, the ridge machining order was reversed. The evaluation of the feature geometries proved that new strategy could improve the feature quality. The ultimate goal was to improve the surface functionality.
