Abstract
New demands are being placed on monitoring systems in precision manufacturing because of recent
developments and trends in machining technology and machine tool design. This paper first
discusses the requirements for sensor technology for precision manufacturing process monitoring in
general. Then, background and details are given about acoustic emission (AE) and the application of
AE sensing to process characterization and monitoring in ultraprecision machining. A review of the
research on AE in machining (including, polishing, lapping and diamond turning) and signal
processing at the University of California at Berkeley is included.
