Engine test bed for experimental investigation.
By Werner Schandor - In the CHIP project, Ceratizit Austria, TU Darmstadt, Material Center Leoben and TU Graz are improving the recording and analysis of heat flows in milling machining. With sensational results. . "What is sensational about our project can be found hidden away in this rather inconspicuous chart," says Franz Haas from the Institute of Production Engineering as he points to a diagram reproducing a saw-toothed temperature progression for the period of a tenth of a second (Figure 2). The cutting temperature resulting from milling a titanium alloy (Ti64) was measured on the cutting edge. The sampling frequency necessary for this amounts to 20 kHz and was only possible due to a piece of hardware developed by the Institute. In other words: 20,000 temperature values are captured and processed in 1 second.
