Time Domain Analysis

Many machining processes show no time-invariant behavior, which is required in order to carry out an operating vibration analysis. The processes vibrate only briefly or change their direction, vibration amplitudes or frequencies. In these cases, monitoring of how the machine behaves over time during the machining process must be carried out. We offer a direct monitoring of these movements using vibration sensors placed at discrete points of the machine structure.  The analysis is similar to the modal analysis in that it is in the form of a moving measurement points grid.

Examples of application

  • Direct representation of the dynamic motion of a spindle head / carriage at critical milling processes
  • Vibration behavior during milling processes with stability differences in co-and counter-rotation.
  • Separation of displacement and self-deformation due to the tilting movement of the column of a machine
