Reference work entry



Ultra-small micro end mills (USM mills) are defined by a diameter smaller than 50 μm. They are often used to cut ductile materials for structures with small radii, undercuts, and tool diameter determined geometries when the accessibility for machining is diameter dependent (Fig. 1). For example, they are used to fabricate medical instruments, micro valves, and so on (Masuzawa 2000; Onikura et al. 2004).
