Micro-Touch Detection Using Acoustic Emission Sensor On Inconel 718

An intelligent non-destructive method of monitoring and 
detecting failures in machining processes is very 
important. Acoustic Emission (AE) sensors has been 
used as a non destructive technique in the past for crack 
and wear detection in workpiece and machine tools. This 
poster presents the efficacy of using AE sensor for touch 
detection during probing.
