Different machines to meet all needs
IN the cost-conscious world of manufacturing, any new process that saves time and money is likely to be very popular. This is especially true for precision optical components, which would be more widely used if they cost less to produce. Livermore's award-winning OptiPro-AED (acoustic emissions detector) should help make the grinding process a reality.

The acoustic emission generated during the grinding process is analyzed to determine its sensitivity to process efficiency and the condition of the grinding wheel. Acoustic emission from surface grinding is used to measure wear-related loading of the grinding wheel and sparkout (or loss of contact) between the wheel and the work surface.
