Application of the Regeneration Spectrum Method to Wheel Regenerative Chatter in Grinding

Abstract

A convenient stability analysis technique for the approximate computation of wheel regenerative chatter growth rates in cylindrical grinding processes is presented. For such processes, the locations of the roots of the system characteristic equation in the complex plane are simply related to a function of frequency, termed the regeneration spectrum, which is easily determined. The usefulness of the regeneration spectrum method is illustrated by applying it to study the dependence of chatter growth rates on grinding conditions and to evaluate the effectiveness of changes in the machine structure in improving chatter behavior, for example cases of wheel regenerative chatter.
