Abstract
In recent years, vibrations of the machine-tool systems have been investigated by many researchers and so many available knowledges have been given. But, about torsional vibrations, only a little investigation has been carried out from luck of the appropriate measuring method. So, for the further experimental analysis of this field, a new measuring method has been developed by the utilization of a marketing wow-flutter meter usually used for the audio recording and reproducing apparatuses. In this paper, the principle and the basic characteristics of this method are discussed and an example of the application, the measurement of the arbor speed variation of the typical small horizontal milling machine, is shown. Main results are as follows: <BR>(1) The developed method not only has a better high frequency response (280 Hz: -3 dB) in comparison with hitherto reported ones but also can make the measurement comparatively easy and measure even small variations below 0. 1% p-p of mean speeds with a good accuracy. <BR>(2) The application shows that even in the racing condition the arbor speed of the tested machine variates with the maximum amplitude of 0.2-0. 3%p-p of the mean speed and the dominant frequency components of this variation mostly result from (a) the fluttering of V-belts between the drive motor and the gearbox, (b) the eccentricity of the arbor, (c) the torsional resonance of the driving system and (d) the gear-noises rising in the gearbox. These aspects may be generally applicable to other machines too.
