Modeling of Vibration and Dithering in SPDT

Abstract

The objective of this work is to develop a model to simulate the effects of vibration on the surface finish of single-point diamond turned parts. This model can be used to optimize cutting conditions for best surface finish and to predict geometric characteristics of the surface beyond the conventional rules of thumb. In addition to small-amplitude oscillations due to machine vibration in the normal direction, purposely induced large-amplitude vibrations in the lateral direction to reduce coherent scatter in the finished part were modeled.
