Abstract: A non-contact on-machine measurement method is proposed for evaluating the profile accuracy of curved diamond cutting tools. The system is based on a compact white-light interferometer which is mounted on a three-axis numerical-controlled ultraprecision machine tool. An algorithm was developed to automatically identify the cutting edge location using the three-dimensional measurement data. Then the cross-sectional profile of the tool is extracted and the distribution of tool profile error is obtained. To measure tools with wide window angles and large curvatures, a data-stitching technique has been proposed for connecting the individually measured profiles from various orientations of the tool.

Keywords: curved diamond tools; ultraprecision cutting; data stitching; white-light interferometer; on-machine measurement; nanoprecision; tool profile accuracy; NC machining; cutting edge location; tool profile errors; tool orientation.
