Abstract

In this study, we develop a high-speed air turbine microspindle with a built-in microphone and pressure sensor, to detect the breakage and wear of a micro tool and to detect anomalies in the bearing and other spindle components. The pressure sensor is employed to detect torque nonuniformity during machining, by using the frequency analysis of signals measured by the pressure sensor. The microphone is employed to detect anomalies in the bearing and other spindle components. The results show that the high-speed air turbine microspindle with a built-in microphone and pressure sensor can detect variations in the microtorque and the frequency components of rotation of the balls of the ball bearing; using the frequency analysis of signals measured by the pressure sensor and microphone.
