Abstract

The paper describes an analytical milling stability model that includes process damping and presents a database of the process modeling coefficients for selected hard-to-machine materials: 1018 steel, 6A1-4V titanium, and 304 stainless steel. The velocity-dependent process damping force applied in the analysis relies on a single coefficient that is obtained experimentally. The database includes coefficients for the process damping model, specific cutting force, and Taylor tool life model. Coefficients are provided for two relief angles and at both low and moderate wear states. Additionally, a wavelength parameter is presented that enables the traditional analytical stability model to incorporate the process damping stability increase observed at low cutting speeds. It is proposed that this database will provide a valuable starting point for hard-to- machine material milling applications.
