Abstract
An on-line and in-process based monitoring system lo detect tool breakage via an acccelerometer was developed and successfully evaluated in an end milling operation. Prior to testing and evaluation of the tool breakage condition, a simulation model was developed. Transfer of the on-line vibration signal to the frequency domain employed the fast Fourier transfer function, and set thresholds were used lo determine the tool condition after various experimental tests.
