摘要： 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.

摘要： 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.
