| Popis: | Effective prediction of surface variation is of great helpf for developing and controlling machining process to maintain surface quality during face milling of large-scale component with discontinuous surface. However, the simulation ranges of machined surface error in traditional finite element analyses are far less than those needed in characterization of large-scale face milling with multi-tooth cutter in order to maintain efficiency. To address this issue, this paper attempts to develop a numerical methodology to estimate the field data of machined surface error based on iterative finite element analysis integrated with cutting trajectory reconfiguration. Finite element model updating (FEMU) method is applied to analysis the cutting deformation in each cutting instant while considering both the cutting force variation in face milling and the locally geometrical differences of component. A flexible model is established to predict the residual cutting material in each cutting instant with considering the coupling effect between instantaneous cutting force and cutting deformation. And then a sub-iteration scheme is proposed to calculate the equilibrium deflection and the real residual material of flexible cutting system with a modified Newton-Raphson method. The proposed simulation methodology can be generally applied for predicting surface variation field in face milling of large-scale component with multi-holed surface, especially for flexible component. |
