Abstract: Systems and methods relating to automated machining. A machining tool is controlled by an industrial robot that guides the tool around the contour of a workpiece. As the tool traverses the estimated contour of the workpiece, the tool machines the surface while a force sensor provides force readings, the force readings being readings of the force exerted by the tool on the surface. The path followed by the tool around the contour of the workpiece is adjusted based on the force readings. The speed at which the tool traverses the workpiece may be modulated and the path may be adjusted based on estimated tool wear.

Abstract: Described herein are embodiments of a virtual currency bank that includes a sealed container that includes an exterior surface and defines an interior, a QR code, located on the exterior associated with a public key that is tied to a virtual currency account, in that the QR code may be scanned to access the public key in order to add funds to the virtual currency account, and a private key, located in the interior of the sealed container and associated with the public key, in that the private key must be accessed and read to remove or spend funds from the virtual currency account. The sealed container is sealed in a manner so that the private key cannot be accessed without breaking the seal or the container in a manner that cannot be obscured or undone.
