The Design and Finite Element Simulation Analysis of the Tool in Milling Titanium Alloys

Abstract

In this paper, considering material properties and processing characteristics of titanium alloys, the milling tool under the machining condition of large cutting depth and quasi-high speed is designed, and the face milling cutter with integral CBN inserts is developed. Then, the solid model of the CBN face-milling cutter is built by the three-dimensional modeling software Pro/E. At the same time, based on the platform of finite element simulation analysis, the deformation and stress analysis of the overall structures are carried out. It turns out that: the maximum stress of the cutter blades is not in the cutter tip region but distributed approximately along the direction of the main cutting edge, the maximum stress of the tool body is at the bottom of the groove for insert. The maximum stress acting on the wedge is at the bottom of the contact area between the wedge and the cutter body. Strength sensitive area of the clamping screw happens in the connection root. Through the static analysis, the reasonableness of structural design of the tool is evaluated theoretically.
