英文摘要: Microstructure evolution of materials has an important effect on chip formation and fracture process, which is also essential for revealing the mechanism of high-speed cutting. Complex microstructures would make it difficult in analyzing the deformation procedure during cutting process. As a result, in this study, oxygen-free high-conductivity (OFHC) copper, including coarse grains and single phase, is chosen for workpiece material to be machined with high-speed cutting experiments for revealing the cutting mechanisms. Chips and chip roots of OFHC copper under orthogonal cutting conditions with increasing cutting speeds from 750m/min to 3000m/min are collected. The microstructure and fracture characteristics of collected chips are observed by electron backscatter diffraction (EBSD) and...
