Zusammenfassung:	A method is provided for assessing chip breaking performance of a selected tool insert used in finish turning for automated machining operations. The method broadly includes the steps for developing a chip groove classification system based upon selected geometric parameters of commercially available tool inserts. Additionally, the method includes creating a fuzzy rule base utilizing the chip groove classification system and actual chip breaking performance data for the commercially available tool inserts. The fuzzy rule base is then used for assessing the chip breaking performance of the selected tool insert. The method takes into account selected geometric parameters, such as, land, primary rake, secondary rake, groove width, groove depth, groove height and slope of backwall.
