Abstract: This study aims to develop a high precision machining method for difficult-to-machine materials with micro 3D structure. For this purpose, ultrasonically assisted on-surface grinding technique has been proposed and experimental investigations involving difficult-to-machine material workpiece with micro strait ribs of several hundreds µm in width have been carried out using metal bonded diamond wheels. As a result, manufacturing of mirror surface on micro 3D structure can be achieved easily and the grinding forces are decreased by ultrasonically assisted grinding. Additionally, the correlation of the grinding characteristics and with the wheel surface topography during grinding process has also been demonstrated. The obtained results indicate the ultrasonically assisted grinding is extremely effective for high precision machining of difficult-to-machine materials with micro 3D structure.
