  • CALIBRATION ASSEMBLY FOR AN INSPECTION SYSTEM
    Publication number: 20090082899
    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.

  • METHOD AND SYSTEM FOR MEASUREMENT OF A CUTTING TOOL
    Publication number: 20090067704
    Abstract: A method for measurement of a cutting tool is provided. The method comprises positioning the cutting tool on a moveable stage, performing a first rotary scan of a first section of the cutting tool to generate a first scanning point cloud, segmenting the first scanning point cloud, performing a second rotary scan of the first section based on the segmentation of the first scanning point cloud, and extracting the parameters of the first section based on the second rotary scan of the first section. A system for extracting parameters of a cutting tool is also presented.

  • System and method for extracting parameters of a cutting tool
    Publication number: 20070124015
    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.
