Publication number: 20140238119Abstract: A method for obtaining an edge prep profile of a cutting tool with a point sensor. The method includes: (a) scanning edge points of the cutting tool, including a target edge point on a target edge, with the point sensor, by rotating the cutting tool around its axis, to generate a first point cloud; (b) repositioning the point sensor and cutting tool relative to each other based on the location and orientation information of the target edge point, such that the sensor focus is at a region of interest containing the target edge point; and (c) scanning the region of interest using the point sensor to generate a second point cloud. The first point cloud includes location and orientation information of the target edge point. The second point cloud includes information for edge profile analysis.Type: ApplicationFiled: August 29, 2012Publication date: August 28, 2014Inventors: Xiaoming Du, Kevin George Harding, Howard Paul Weaver, James Allen Baird, Kevin William Meyer, Jiajun Gu

Publication number: 20110317909Abstract: 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.Type: ApplicationFiled: June 29, 2010Publication date: December 29, 2011Applicant: GENERAL ELECTRIC COMPANYInventors: Satheesh Jeyaraman, Kevin George Harding, Anandraj Sengupta, Debasish Mishra, Suneel Tumkur Shankarappa, Howard Paul Weaver, Kevin William Meyer
