Using the finite element numerical simulation method to simulate the process, guide the process test and select process parameter is an important way to improve the design efficiency. This paper analyzes a typical tube manufacturing process for Ti-3Al-2. 5V tube bending with finite element method, in order to provide the basis for reasonable selection of tube bending radius and bending angle. Finite element numerical analysis method is also introduced into the tube bending process design for reference.
