Abstract

This paper predicted the relationship between chip shrinkage coefficient and cutting parameters such as cutting speed, uncut chip thickness in a cutting process of A6061 aluminum alloy. The chip shrinkage coefficient was determined through simulation using finite element method. The commercial software Abaqus/Explicit is employed for simulation of the cutting process of A6061 alumium alloy based on the Bao-Wierzbicki fracture model. Then, the least square method was used to derive the relationship between chip shrinkage coefficient and cutting force. The above-mentioned relationship is believed to be useful in determination of optimal cutting conditions in high-speed machining.
