Progression of Cutting Tool Wear and Vibration Emission in the Grinding Process

Abstract

This study investigates the progression of cutting tool wear in grinding by analysing vibration emissions. The measurement was conducted under a repeated single operating condition. A cylindrical carbon steel workpiece was ground using a CNC grinding machine with coolant. Vibrations were measured along the X, Y, and Z axes using a Dytran 3-axis piezoelectric accelerometer, with data collected via NI DAQ 9234 at 12.8 kHz. A total of 70 grinding cycles were performed at 3000 rev/min (50 Hz). Root mean square (RMS) values of vibration signals were extracted as well as kurtosis, skewness and variance, to evaluate the correlation between tool wear progression and vibration characteristics. The findings highlight the sensitivity of vibration response to gradual tool wear. This study demonstrates the potential of using vibration measurement as a reliable indicator for monitoring grinding performance, improving process stability, and enhancing product quality.
