A novel method for machine tool multi-body system restrained by stiffness field is proposed to solve the difficulty of discontinuous machining error prediction result. According to the characteristics of multi-body system kinematics solution
the machine tool component is considered as an elastic body
and the lower body array and transfer matrix are used to describe the motion relationship between the machine tool components. Following the condensation approach of stiffness matrix and the least square evaluation
the stiffness model under moving load of machine tool component can be obtained. Then Jacobian matrix is taken to construct the machining error prediction model. This method is verified in a boring milling machining error prediction for an engine cylinder head. The combined machining error prediction method enables to optimize the angle of clamping in engine shell machining process. Describing multi-body system by lower body array facilitates evaluating errors in united machining process. According to the combined machining error prediction
the machining precision can be increased by 35% at working degree of 90°.
