Study on Simulation of Machining Deformation and Experiments for Thin-walled Parts of Titanium Alloy

Deformation problems are main factors affecting the precision of machining the thinwalled parts. This paper focuses on the thin-walled parts of titanium alloy that is the difficult-to-machine material, based on the analysis of deformation characteristics and force, the milling force mathematical model of the ball-end milling cutter was established. On the basis of the 3D milling model of thin-walled parts of titanium alloy, the deformation regularity and cutting force variations were analyzed with the finite element simulation method. Through the experiments of machining thin-walled parts, the cutting force model was verified. The experiments results and simulations results match well. The work provides an effective basis for further study on the control of machining deformation of thin-wall parts of titanium alloy.
