Tool condition monitoring is a means to increase the reliability and efficiency of machining through tool breakage detection and wear monitoring. This paper provides the relevant knowledge about the state of the art in monitoring drill condition with acoustic emission to support a successful choice of sensors for a monitoring system. In drilling acoustic emission (AE) sensors are successfully applied for breakage detection. Attempts have been made to monitor wear with acoustic emission. The theory for the effect of wear on acoustic emission is reviewed. A set of experiments has been evaluated in order to illustrate characteristics of the AE-signal in drilling. Experiments for 4 and 10 mm drills with MoS/sub 2/- and TiN-coating have been chosen to show the effect of the coating on acoustic emission. The soft MoS/sub 2/ coating provides a dry lubrication layer whereas the hard TiN coating protects the tool through wear resistance. Additionally, the feed force, which is the common signal used for drill wear monitoring, has been recorded during the experiments to illustrate the difference in the validity of the signals.
