Research on Influence of Milling Parameters on Machining Deformation of Rectangular Thin- Walled Parts

摘要

Aiming at the problem that the machining accuracy of rectangular thin-walled parts are difficult to ensure because of poor rigidity and machining deformation which is easy to produce extremely, it used the three-dimensional finite element method and did analysis and calculation of rectangular thin-walled parts under the action of milling force. It obtained the machining deformation law and the changing trend of the machining deformation of rectangular thin-walled parts with milling parameters in the different milling parameters circumstance by adjusting the milling parameters (milling depth, milling width, feed rate). It provided the theoretical basis for the selection and optimization of thin-walled parts milling parameters in the actual milling process.
