NC (numerical control) table is one of the main components of NC machine. Factors such as backlash, friction and elastic deformation among each part have become the bottleneck for feed system to enhance positioning precision, tracing precision and dynamic behaviors. There are many researches on dynamic behavior of NC table, but only few focused on its nonlinear dynamic characteristics.
