Abstract

To reduce the excitation of structural oscillations machine tools’ feed dynamics are usually limited. Thus, their productivity is restricted, especially for high dynamic processes with negligible process forces. The principle of Kinematically Coupled Force Compensation (KCFC) tries to overcome this issue by combining a redundant axis configuration with the principle of force compensation. In this paper, based on a short introduction considering the overall motivation and the KCFC principle, an overview of the design process of a 2D-KCFC test bed is given. This includes the simulation-based design of the slides, the machine frame and the electric voice coil drives. Subsequently a simulative analysis, facilitating a Multibody Simulation (MBS) for the investigation of the mechatronic system operated at highest feed dynamics and controller cycle rates, is performed. This simulation illustrates the possible reduction in process time and validates the effectiveness of the test bed’s torque decoupling concept.
