General Cutting Dynamics Model for Five-Axis Ball-End Milling Operations [PDF]

Journal of Manufacturing Science and Engineering, Transactions of the ASME, 2020
Five-axis ball-end milling has been used extensively in the manufacturing of parts with sculptured surfaces. This paper presents the general cutting dynamics model of ball-end milling process for machine tools with different five-axis configurations. The

Five-axis milling of spherical surfaces

International Journal of Machine Tools and Manufacture, 1996
A new five-axis technique for machining of spherical surfaces with a radiused or flat bottom end mill is presented. The tool path generated by the proposed technique produces scallop free surfaces at a fraction of the time required by conventional milling using a ball nose end mill. The proposed method was verified experimentally on a wrist type and on

Modeling regenerative workpiece vibrations in five-axis milling

Production Engineering, 2008
During milling—especially of thin-walled components—the dynamic behavior of the workpiece-tool-machine-system influences the milling process and particularly the quality of the resulting workpiece surface. This article focuses on the presentation of a simulation concept for predicting regenerative workpiece vibrations, which combines a finite element ...

Virtual Five-Axis Flank Milling of Jet Engine Impellers—Part I: Mechanics of Five-Axis Flank Milling

Journal of Manufacturing Science and Engineering, 2008
This work is the first of a two part paper on cutting force prediction and feed optimization for the five-axis flank milling of jet engine impellers. In Part I, a mathematical model for predicting cutting forces is presented for five-axis machining with tapered, helical, ball-end mills with variable pitch and serrated flutes.
