| NC integral panel structure deformation is facing one of the aviation industry’s most prominent issue that has plagued the aviation industry. In order to get rid of dependence on imported thick aluminum material, playing bankruptcy bottlenecks, and only rely on domestic aluminum alloy thick plate processing.The overall impact of the domestic aluminum alloy sheet panels machining distortion factors for predicting and controlling the overall aviation cover CNC machining distortion, reduce or suppress the deformation of the parts during machining is of great significance and value.Thus, the study of these components deformation of thin-walled parts processing relationship between the amount of control pressure and milling distortion between important. To the theoretical model of milling force established thin-walled parts, we first need to establish a theoretical model of milling force is not considered under the premise of deformation of the workpiece. In this article,the use of static strain measurement, strain engraved during the acquisition cycle, confirm the trend of residual stress distribution model; access to relevant information: Learn about finite element analysis theory; deformation of thin aluminum siding parts processing finite element modeling and analysis of instantaneous deformation. In order not to consider the aluminum side milling force deformation based on theoretical models, thin-walled parts machining milling force adjustments and amendments, ultimately, milling force model theoretical model theory of deformation of thin-walled plate-type parts. Side by thin-walled parts Milling test a theoretical model for further experimental verification. In summary, thin-walled side panel parts Milling Force proposed model can simulate the size and direction of the thin-walled parts milling force,base quality and deformation of thin-walled parts Control of subsequent processing, there are some theoretical guidance value. |
