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.

Method and system for measurement of a cutting tool

A method of measuring an object includes positioning the object on a moveable stage, performing a rotary scan of the object with a range sensor, and determining geometric parameters of the object based on the rotary scan.

Methods and system for measuring an object

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.
