| Sunday, October 15, 2006 8:00 a.m. to 12:00 p.m. Acoustic Emission Monitoring of Precision
Machining This tutorial provides an overview of acoustic emission sensing technology (AE), a sensing technology based on high frequency stress wave generation and propagation in solids, and its potential as applied to precision machining applications. The first half of the course reviews the motivation and requirements for sensors as applied to precision machining. The basics of acoustic emission including sensor characteristics and AE sources in materials and manufacturing processes is included. Signal processing strategies for AE data will be reviewed and illustrated. The second half of this course will focus on the mechanics of precision machining and their influence on acoustic emission signal generation. Examples of application of AE sensing including: conventional machining, single point diamond turning (SPDT), the effects of grain size/orientation in machining, ductile/brittle effects in machining, tribology and grinding, polishing/lapping and chemical mechanical planarization (CMP) is presented. A review of commercial sensor and signal handling hardware is presented along with a literature review (including several appropriate technical publications) for those seeking additional information. Tutorial handouts will include copies of material presented and selected articles on acoustic emission in precision machining, as well as a bibliography for research in this area. This course is intended for personnel who are engaged in precision machining as part of their research or profession, are interested in AE capability for particular monitoring applications or are engaged in process or system development for challenging machining processes. Some familiarity with basic precision manufacturing processes and instrumentation is helpful.
