Abstract

A study was carried out to investigate the mechanism of burr formation in micro-scale-mechanical machining (henceforth referred to as 'micro-machining') of Oxygen-Free-Copper (OFC) using a 5-axis ultra-precision machine. The single crystalline diamond (SCD) micro-tools with a cutting contact length of around 30 μm on the primary clearance face were employed in this study. Burrs could be observed when the cutting depth is deeper than 0.9 μm. The crystallographic orientation exerts a great influence on the formation of the burrs. Modifying the machining parameters, such as reducing the cutting depth or the cross-feed rate could minimize the burr size. This study contributes to the understanding of the physics of mechanical machining with micro-tools.
