A novel hybrid machine tool(HMT) with mechanical system reconfigurable ability is present, fault-tolerant reconfiguration strategies for HMTs are studied, a novel fault-tolerant reconfiguration approach for mechanical system faults of hybrid machine tools is proposed based on mechanism type transformation, implementation strategy for spherical joints transforming into huke joints is given. Inverse displacement analysis algorithms are deduced for both fault and non-fault status of HMTs, simulation analysis and research are conducted based on ADAMS desktop, self-rotation angle curve as well as joint space trajectory curves for before and after reconfiguration are obtained, simulation results show that the safety and reliability of HMTs can be enhanced utilizing the reconfiguration characteristics of mechanical system.
