In-situ synchrotron x-ray diffraction studies in the chip formation zone during orthogonal metal cuttin

Abstract

In the field of metal cutting a very important parameter is the chip formation zone, where the workpiece, the cutting tool and the chip are in contact. The transient processes inside this zone decisively define the properties of the workpieces near surface zone, e.g. residual stress distribution or the local microstructure. With the development of a special designed turning device we established a methodology to gain insight into the chip formation zone of a workpiece during the turning process with high spatial and temporal resolution. Using the dedicated device we were able to access the strain evolution during a cutting process of aluminum alloy AW-5754 with a measuring rate of 10 Hz inside the chip formation zone.
