Abstract:
A device which independent of machine tool parameters provides rotational speed recommendations for relative rotation between a cutting tool having at least one cutting edge and a workpiece whereby such speeds are likely to result in the reduction or elimination of chatter comprising:(a) a transducer for sensing vibrations including the chatter between the cutting tool and workpiece and providing an electronic signal corresponding thereto;(b) means for conditioning the signal to optimize the amplitude and attenuate unwanted frequency components;(c) means for processing the conditioned signal to determine the frequency of the dominant spectral component;(d) means for inputting the number of cutting edges on the cutting tool;(e) computing means to calculate rotational speed recommendations as a function of the frequency of the dominant spectral component and the number of cutting edges; and(f) means for displaying the rotational speed recommendations.
