Abstract

In this work, an experimental and theoretical studies are given for the well-known process damping effect arisen in turning processes. This effect generally pushes the stability chart (lobes) to higher depth of cuts in low spindle speed domain and causes difficulties to predict the stability of stationary cutting (equilibrium of the process). The orthogonal cutting model presented and investigated here contains distributed delays due to the cutting force distribution on the rake face. The paper presents measurement set up to create and to track the oscillating cutting force for the identification of the model parameters. An extended model also investigated that explains the experimental observations.
