Abstract

Chapter 3 describes regenerative chatter in turning. To predict turning behavior, both analytical and numerical analyses are presented. The analytical, frequency domain stability lobe diagram is derived that describes the limiting stable chip width as a function of spindle speed. A time domain simulation is detailed that determines the dynamic cutting force and tool displacement in turning by numerical integration. The simulation is then used to identify stable and unstable cutting conditions. Finally, the specific application of modulated tool path turning and the effect of process damping on turning stability at low speeds are presented.

We represent \( \overrightarrow{y}(t) \) and \( \overrightarrow{y}\left(t-\tau \right) \) as vectors because they have both a magnitude and phase relative to the force, F_n. The force and both displacement vectors are displayed in Fig. 3.10.

In other words, the ratio of the chatter frequency to forcing frequency cannot be expressed as a ratio of whole numbers.
