Study on Cutting of Micro Channel by End Mill with Small Diameter

Abstract

This paper describes the cutting characteristics and the shape error of groove when PMMA and PTFE are finished by the end mill with small diameter. Direct cutting experiments of micro channel by a miniature end mill were carried out in order to consider the possibilities of the fabrication of micro devices by machining. As the results, it was found that the surface roughness of 1 μm Rz or less was obtained and the width of channel became less than the tool diameter and the deflection of the end mill caused by …
