Tool condition monitoring using vibration measurements - a review

Techniques for achieving tool condition monitoring (TCM) with vibration related parameters are presented. Sensing methodologies that include cutting force and torque, tool and machine vibration response, airborne sound pressure and acoustic emission are discussed as examples of parameters that have been used for TCM. Signal processing to extract and select features related to tool wear, is subsequently discussed. This is followed by a discussion of techniques for wear modelling and diagnostics. The possibility of combining TCM with active control of the tool vibration response is briefly considered.
