In Chapter 2, we discussed how to use modal analysis to describe the tool point dynamics for tool-holder combinations. In this chapter, we’ll discuss regenerative chatter in turning and see how we can apply the dynamics information to develop stability lobe diagrams that describe the limiting chip width (to avoid chatter) as a function of spindle speed. We’ll also detail a time-domain simulation for predicting cutting force and tool displacement which also enables us to determine stable and unstable cutting conditions.
Turning operations are generally carried out on a lathe where a workpiece is rotated in a spindle past a tool mounted on a two axis slide in order to give the desired shape to the axisymmetric part; see Fig. 3.1.1. The final shape can include both internal and external features. The lathe may be manual, where a machinist controls the slide positions during material removal, or computer numerically controlled (CNC). In this case, automatic control is us ...
