    Abstract: 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.

    Abstract: A method for extracting parameters of a cutting tool is provided. The method includes obtaining a measurement data set having a point cloud corresponding to a surface of the cutting tool and virtually slicing the point cloud at a pre-determined section to obtain a set of points on the pre-determined section. The method also includes generating a plurality of curves through the set of points and optimizing the plurality of curves to generate optimized fitting curves and extracting the parameters of the cutting tool from the optimized fitting curves. Furthermore, based on the presented rotary angle projection technique, a plurality of parameters can be extracted for the cutting tool.

    Abstract: 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.
