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.
