Dynamic Characteristics of Small Diameter End Mill

Abstract

The dynamic response of small diameter tools is measured to simulate the dynamic cutting process in micro-scale milling. The inclined ball end mills are excited with measuring the exciting force on the vibration generator. The modal parameters are estimated with changing the cutter axis inclination and the overhang of the tool. A vibration model is presented to show that the vibration is subjected in the radial direction of the small diameter tool. The dynamic cutting process is simulated to show the effect of the spindle speed on the tool displacement based on the estimated modal parameters.
