The regenerative chatter in micro-milling that is employed to produce small products with complex 3D geometries and high precision is gradually getting attention from researchers in the field of manufacturing, mechatronics and control for its severe damage to the cutting tool and micro-milling stability. To facilitate developing observer-based control strategy for suppressing the regenerative chatter, the integrating an adopted observer proposed for nonlinear systems with time delay and a practical regenerative chatter model for micro-milling is presented in this paper. And the observer analysis is shown. Simulation results are given to validate the integration scheme.
