ABSTRACT:
A non-contact, non-destructive measurement method and system for the edge of parts such as the cutting edge or "hone" of tools wherein the shape and dimensions of the hone are measured with high accuracy (i.e., within 5 microns) and repeatability. Given a tool that is mechanically fixtured under the system and a set of user-defined parameters, the measurement system automatically detects a measurement area for different orientations of the tool. Manual selection of the measurement area is also possible. The system then uses a combination of Moire interferometry and image analysis algorithms to compute the shape and dimension of the hone for both radius and waterfall types.
