Tool Life Detecting System using Damage Sensor-integrated Insert

概要

論文の詳細を見る
In-process tool life detecting system has been developed. To detect tool life, a TiN thin film band having electric conductivity was coated parallel to cutting edges on flank face of a ceramic insert having no electric conductivity. A coil and a capacitor were connected in series to the sensor insert to make a series resonance circuit in a tool holder for turning, or in an arbor for face milling. A detecting coil with high frequency oscillator was coupled to the coil in the holder/arbor electromagnetically. An electromagnetic induction between two coils was used to take the signal from the insert. The system developed in this study showed good stability against electric noises from an environment especially machine tools.
