Figure 1From: A Rotating-Tip-Based Mechanical Nano-Manufacturing Process: NanomillingTwo fundamental rotational motions of the tip: a In-plane motion, and b Out-of-plane motion. The nanotool follows the indicated path to remove the material. Two instants of the cross-section of the nanotool are indicated as 1 and 2. Continued nanotool rotation will remove the dark-shaded portion of the sampleBack to article page
