Active center position control of machine tool spindle

抄録

More efficient internal combustion engines have been required for global warming countermeasures. In order to overcome the problem, one of the most efficient method is to realize a non-axisymmetric non-circular inner cylinder machining within several tens of micrometres. However, there is no machine tool coping with the machining method. Our research purpose is to develop the high-performance spindle that can machine parts with non-circle machining such as the inner cylinder profile for EV motors and internal combustion engines with high precision. Based onthe model base simulation, the performance of the positioning control was evaluated by applying a disturbance assuming the cutting force actually applied. Finally, we evaluated the performance of the disturbance observer using the actual spindle.
