Carbon fiber reinforced plastics are widely used in aerospace and aircraft industries because of their remarkable advantages such as lightweight and high strength. However, as their properties are different with metals, those materials are difficult to machine in conventional ways, the machining defects may appear and the machining accuracy and surface quality are difficult to guarantee. Oriented to drilling of carbon fiber reinforce plastics, a machining model based on finite element method are presented in this paper, the drilling simulation of carbon fiber reinforced plastics using Deform-3D are realized, and the factors which influence the machining quality of the hole are analyzed in-depth. It shows the simulation results are accord with the results from the literatures and experiments and can used as evidence in drilling parameters optimizing and drilling quality improving. |
