The Correlation of Vibration Signal Features to Cutting Tool Wear in a Metal Turning Operation

This paper describes a tool-wear monitoring procedure in a metal turning operation using vibration features. Machining of EN24 was carried out using coated grooved inserts, and on-line vibration signals were obtained. The measured tool-wear forms were correlated to features in the vibration signals in the time and frequency domains. Analysis of the results suggested that the vibration signals’ features were effective for use in cutting tool-wear monitoring and wear qualification.
