Transformation of Cutting Burr/Fracture in High-Speed Machining Al Alloy

Abstract

The metal cutting burr is one of the factors that influence the edge quality and performance of precision parts.A finite element model has been established to investigate the mechanism of burr formation and limit transformation in high-speed machining 2024Aluminum alloy .The burr/fracture formation process is simulated with elastic-plastic nonlinear element method based on ABAQUS.This paper has investigated the mechanism of burr /fracture formation and the limit transformation condition of cutting-direction burrs and fractures in high-speed machining and the limit transformation condition change with the cutting condition,which lay scientific basis of further research on cutting burrs formation and its minimization and deburring technology.

Formation and Simulation of Negative Shear Zone

“…The existence of burrs has become one of the key problems that influence the development of automatic machining, flexible process and precise manufacturing. Since the 1980's, many scholars have conducted much study work with experimental and theoretical methods and some achievements have been obtained [1][2][3][4][5][6]. However, the forming process of cutting direction burr/fracture is influenced by many factors; it is difficult to predict them exactly.…”

Formation and Simulation of Cutting Direction Fracture

“…The existence of fracture has become one of the key problems that influence the development of automatic machining, flexible process and precise manufacturing. Since the 1980's, many scholars have conducted much study work with experimental and theoretical methods and some achievements have been obtained [1][2][3][4][5][6]. However, the forming process of cutting direction fracture is influenced by many factors; it is very difficult to obtain precision analytical solution for general problems with large deformation such as chip and fracture formation processes.…”
