Abstract
Miniaturized components are increasing in demand for various application, such as aerospace, biomedical, electronics, communications and automotive. Micro-milling is a method to fabricate miniature devices and components with features that range from tens of micrometers to a few millimeters in size.his study presents an experimental investigation of the different tool diameter with 0.3mm, 0.5mm and 10mm of 6061 aluminum alloy and S20C steel in traditional milling and micro milling process. It is found that cutting under higher spindle speed results in worse surface roughness due to chip adhesion. The chip always turns into arc chip and powdery in the micro milling process. But these phenomena are not easy to occur in the traditional milling process. This paper proposes a method which send the cutting fluid to the cutting zone by using compressed air may improve the surface roughness and adhesive wear of the tool.
