Abstract:
This paper presents a three-dimensional mechanistic
frequency domain chatter model for face turning processes,
that can account for the effects of tool wear including
process damping. New formulations are presented to model
the variation in process damping forces along nonlinear tool
geometries such as the nose radius. The underlying dynamic
force model simulates the variation in the chip
cross-sectional area by accounting for the displacements in
the axial and radial directions.
