A new NC table driven by twin linear motors has been developed for us machining curved surfaces by lathe turning. This turning method enables us to machine the un-axisymmetric noncircular profiles with high acceleration and deceleration. The key factor for this turning method is to precise trace trajectories on a designed surface. The NC table requires a dynamic response that leads to a rapid motion with high acceleration and jerk. In this study, we propose a new NC table with acceleration and deceleration that exceeds 10 G with the use of a linear motor; this table enables high-speed contouring machining. Here, the fundamental performance of the table developed is reported. Motion and inertial forces are evaluated from the measurement results. The capability and effectiveness of the NC table developed for machining 3D surfaces are also reported.
