Thin Wall Part

Aircraft components are mostly made by aluminum alloy as thin wall types. These parts are usually end milled to required thicknesses and tight tolerances in specific areas. The thin wall parts are difficult to machine because they are easy to vibrate and deformed due to their lower rigidity. This paper proposes a new elastic-plastic deformation model which is suitable for prediction of machining deformations of end milled thin wall parts. The theoretical deformation model is established on the basis of the equations of Von Kármán. The part deformations are simulated using FE analysis and Matlab. The results show that the deformations for the end milling of thin wall parts can be captured with very high accuracy using the proposed elastic-plastic deformation prediction model.

Thin Wall Part

A numerical simulation mathematical model and sloved method about injection forming for thin-wall part was established. Based on it, Simulation of the injection forming process of centrifugal separation disc. Through the simulation of forming process for PA66 and PA66+30%GF two kinds of materials, realized the injection forming for centrifugal separation disc using PA66+30%GF. Through the anisotropy of glass fiber orientation, improve the stiffness and toughness for centrifugal disc.

Viscous pressure forming (VPF) is a new developed sheet soft-punch forming process in 1900s. The basic principle and characteristics of VPF are described. The applications of VPF technologies of nickel-based super-alloy corrugated thin-walled part, asymmetrical thin-wall part with variable diameter, super-alloy thin-walled part with variable diameters, corrugated thin-walled part with larger diameter and small section are presented. The results show that VPF is suitable for the forming of parts with high strength, low plasticity, super thin-wall and complex shaped.
