SIMULATION STUDIES ON CHIP FORMATION PROCESS IN HIGH SPEED MILLING OF ALUMINIUM ALLOY

Pham Thi Hoa

Abstract


Simulations of chip formulation mechanism and phenomenon ccurred in cutting processes can help to reduce time and cost comparing with experiment. Finite element method (FEM) is an effective and accurate technique, which can be used for simulation of cutting process. In this paper, chip formulation process in high-speed milling of A6061 aluminium alloy is investigated using FEM based on the Johnson-Cook (J-C) and Bao-Wierzbicki (B-W) fracture models. The Von-Mises stress distribution and equivalent plastic strain (PEEQ) during cutting are then investigated. Finally, the evolution of cutting forces in cutting was examined. The presented Finite element model in this study proved to be useful in determination of cutting parameters, especially in high-speed machining.
