Development of a Fibre Optic Sensor for in Process Measurement of Tool Flank Wear

  • F. Giusti
  • M. Santochi


After a general discussion about the importance of tool wear sensing in the automation of manufacturing processes, requirements for industrial utilization of sensors are described.

Based upon a critical assesment of the state of the art, a new optical sensor is escribed in its working principle. Constraint control of a prefixed VB value and real intermittent measurement of VB value are possible in a simple way. Results obtained in experimental tests carried out measuring several worn carbide inserts are given.
