    An in-process tool wear meter for turning has been developed by combining a sensor-integrated insert and simple signal processing technique. The sensor consists of TiN thin lines, which are deposited on the flank of each cutting corner of ceramic insert in parallel with the edge. As flank wear causes breakage of the lines, a step increase in sensor resistance occurs. This feature of the resistance... View full abstract»
