Study on Milling Deformation of Ruled Surface Blade

Abstract

Integral impeller is the key component in aviation, aerospace and other fields, and the deformation has an important effect to the machining quality and precision of the integral impeller. Because of the complexity of the geometry and surface curvature changes for the integral impeller, and the semi suspended state during the processing, force analysis and control technology for the deformation have become the key and difficulty to realize high quality processing. In this paper, the situation about the blade machining with the finite element analysis is introduced, and the factors about the blade machining deformation is also summarized. The deformation of a single cutter location point are computed and analyzed with finite element method, and the application problems to the machining deformation with the finite element are presented.
