Marc Schmieger

You can determine the vibration (resonance) frequency and their associated amplitudes of your milling machine. The spindle speed at given feed rate etc. results in specific excitation frequencies. They are in the range of 2kHz...5kHz. In case of overlapping frequencies from the force measurement system and the milling machine you are able to distinguish the appropriate components and their amplitudes.

Daniel Martinez Krahmer

Is the manner to know the natural frecuencies of the mill components. If the milling exiting one of the natural frecuencies of the machine, the vibration is high and firstly deteiorate the finish of the piece and the life of cutting tool.
