Amplitude and frequency modulation in wall

The phase lag between large- and small-scale fluctuations for frequency modulation is comparable to that of amplitude modulation in the near-wall region The combined effect of both amplitude and frequency modulation is also examined by computing conditional spectra of the small

Experimental study on high frequency chatter

Vibration assisted machining (VAM) is a technique by applying external vibration at high frequency and small amplitude to create relative displacement between the cutting tool and the workpiece in addition to the original cutting motion Lately the effect of VAM on the chatter vibration was investigated in orthogonal turning process
