Frequency Response Functions for Sandvik CoroBore 825 XL boring tool, 733 mm

Opis

Frequency Response Functions (FRF) obtained for Sandvik CoroBore® 825 XL mounted at WHN 13-15 TOS VARNSDORF CNC machine at the minimum extension of the spindle adaptor. Tool set to bore a hole with a diameter 733mm

The tool was excited with modal hammer consecutively in the direction of accelerometer A18, A21, A22, A29. Responses were measured using 15 accelerometers mounted as on Fig. 1. 40 hammer impacts for each direction were performed. FRF was calculated using H3 estimator from NI LabView Sound & Vibration toolkit. Obvious disruptions in data (“peaks” resulting from the CNC control systems and drive, electromagnetic interference etc.) were removed.
