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.

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 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.

Abstract: A method of calibrating an inspection system is provided. The method includes contacting a test part with a run-out measurement device and rotating the test part and measuring a first run-out using the run-out measurement device. The method also includes moving the run-out measurement device to a new position and repeating the steps of contacting and rotating the test part to measure a second run-out at the new position. The method further includes using the first and second run-outs to adjust measurements of the inspection system.

Abstract: A method which broadly comprises the following steps: (a) submitting to a tool data library a request which includes the basic tool parameters to generate tool specification parameters; (b) generating tool specification parameters from the tool data library based on the submitted basic tool parameters; (c) importing the generated tool specification parameters into a parametric tool template; and (d) processing the imported tool specification parameters and parametric tool template using a CAD software program to create a tool specification, wherein the tool specification comprises a representation of a three-dimensional model of the tool and associated drawing specifications for the tool. Also disclosed is a system which broadly comprises: a requester workstation; a tool data library; a source of parametric tool templates modifiable with imported tool parameters; and a source of a CAD software program for processing the parametric tool templates and imported tool parameters to create tool specifications.

Abstract: A method for reaming a hole in a metal substrate that minimizes the tendency of long and stringy metal chips to be formed that can surround the reamer with a “steel wool-like” mesh or mass of material, as well as an improved reamer for carrying out this method. The reaming method involves longitudinally advancing the chamfered end of the reamer into the hole at an increased rate of at least about 5 mils (0.13 mm) per cutting edge as the hole is reamed during rotation of the reamer. For holes or bores having a length (L) that is at least about 3 times the cutting diameter (D) of the reamer, a preferred subsequent step is to momentarily reduce the rate of advance of the chamfered end into the hole to about 1 mil (0.025 mm) or less per cutting edge for from about 1 to about 5 rotations of the reamer.
