    摘要： 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.

    摘要： A method for extracting gash parameters of a cutting tool, comprises positioning the cutting tool on a moveable stage, scanning two or more gash sections of the cutting tool to generate two or more gash section scanning point clouds, indexing multiple points of the gash section scanning point clouds, detecting multiple gash features using the indexed gash section scanning point clouds, projecting multiple point clouds of the gash features of the indexed gash section scanning point clouds to form one or more projected gash feature point clouds, identifying one or more types of the one or more projected gash feature point clouds, segmenting the one or more projected gash feature point clouds based on the type identification, and extracting one or more gash parameters based on the segmentation of the one or more projected gash feature point clouds. A system for extracting the parameters is also presented.

    摘要： 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.
