Purpose and goal

We aim to explore non-destructive spectroscopic techniques at synchrotron sources to deepen the knowledge of the tool and workpiece material interactions in the tool-chip contact zone. The long-term goal is to identify methods to collect real-time data in operando during cutting and to understand the chemistry in the wear zone as well as its impact on the active wear mechanisms. The experience gained will open possibilities for more advanced experiments and for Seco to independently conduct x-ray based experiments

Expected results and effects

We will explore the possibility and challenges of using synchrotron x-ray spectroscopy with a high spatial resolution to access the chemical compounds that form in the tool-chip contact during machining. Detailed understanding of the chemistry of the wear zone and the role of tool surface (coating) will serve as a base for new innovations, where the tool materials is optimally designed to utilize the reactions occurring. The new knowledge is expected to create opportunities for guiding the development of next-generation cutting tools.

Planned approach and implementation

We will characterize the chemistry at the worn tool using x-ray absorption near edge structure (XANES), extended x-ray absorption fine structure (EXAFS), and x-ray fluorescence (XRF) at MAX IV (Lund) and/or Petra III (Hamburg) when beamtime is granted. Seco Tools will provide expertise on cutting and analytical transmission electron microscopy studies of the wear to verify the x-ray spectroscopy results. Linköping University will lead the synchrotron experiments and the subsequent data analysis. Both partners will participate in the synchrotron experiments.
