Stress distribution in the chip formation zone of fcc materials Al2017 and alpha brass analysed by in situ diffraction

The stress distribution in the chip formation zone during cutting is an asked question in the field of manufacturing technology and leads to a fundamental understanding of the chip formation process. The local strains in the chip formation zone were obtained in situ by high energy synchrotron X-ray diffraction during orthogonal cutting at the HEMS beamline (PETRA III/Hamburg).The present study compares the stress states of two fcc materials, namely the aluminium alloy Al2017 and single phase alpha brass
