US Classification:

356601, 356607

Abstract:

A method for extracting parameters of a cutting tool is provided. The method comprises positioning the cutting tool on a moveable stage, performing one or more rotary scans of a first section of the cutting tool to generate a scanning point cloud, indexing a plurality of points of the scanning point cloud, detecting one or more feature points based on the indexed scanning point cloud, and extracting one or more parameters based on the detected feature points. A system for extracting the parameters is also presented.

US Classification:

416 1, 298892

Abstract:

A method for reducing tip rub loads in a rotor blade is described having the steps of selecting a location of contact between the rotor blade and a static structure; selecting a location on the blade for incorporating a tip-cutter; selecting a cutter-profile for the tip-cutter; and incorporating the tip-cutter on the selected location on the blade such that tip-cutter is capable of removing a portion of the static structure during a tip rub such that tip rub loads are facilitated to be reduced.

International Classification:

G06K 9/00

US Classification:

382152

Abstract:

A portable wear quantification system includes a hand-held image acquisition device and a fixture. The fixture includes a first end coupled to the image acquisition device. A light source emits a light beam along an emission axis. A beam splitter is disposed at an angle with respect to an axis of view of the image acquisition device for directing the beam from the light source toward a portion of an object. A second end of the fixture is located on an opposite side of the beam splitter from the first end. The second end includes a platform that is configured to position the fixture with respect to the object. A channel extends from the first end to the second end along the axis of view of the image acquisition device.
