Study of Modeling and Virtual Machining for predicting distortion of multi-frame components
Because the multi-frame component has thin walls, variable wall thickness and a high reconciliation precision request, the design restrains are many, and the variable is big, the manufacture restrains must be considered in the design stage. In this study, a method called house-building frame modeling is introduced firstly, and the finite element model of the milling distortion analysis is established for the multi-frame components by the method, and the prediction analysis of the milling distortion under different milling conditions is carried out, by means of 3-D finite element simulation technology.Comparing the simulation results and the measurement ones of the milling distortion, the proposed model is modified; the modeling method and prediction method are proved to be effective. Software system is developed specially for the modeling and the distortion prediction for multi-frame part. By using of the software, a platform structure with 192 frames is analyzed and its milling distortion is predicted successfully.
