In recent years, the surface quality requirement in die and mold has become increasingly severe. In addition, die and mold that difficult to polish are increasing, and hence mirror finishing by cutting is required. In order to obtain mirror surface by cutting, it is necessary to reduce influence of tool non-repeatable run-out (NRRO) on machining surface. In this study, we confirmed effectiveness of a prototype excitation system that extracts NRRO component from measured tool run-out signal and reduce it using voice coil motor added to the spindle head.
