3312 Study on Accuracy of Groove Profile in Micro End milling : Influence of Tool Run-out on Geometric Work-errors

Abstract

In micro cutting, high efficiency and high precision processing are difficult, because a micro tool has very low strength and stiffness. In this paper, the groove profile errors are discussed analytically during full-width milling or side milling. In addition, the influences of radial tool run-out upon the groove profile errors are examined experimentally using a micro end mill of 0.1mm in diameter, by monitoring high frequency cutting force. The results require significantly more severe alignment in the radial run-out, in comparison with cutting experiments.
