Cost, weight, performance, and lifetime requirements for precision components used throughout the aerospace and
defense industries are driving innovative mechanical designs, manufacturing processes and use of new materials. In
turn, these advanced components typically require tighter dimensional and surface tolerances to function as designed.
Scratch testers, microscope-based systems, and other traditional metrology systems are inadequate for roughness, small-scale
geometry, and defect determination on many of these parts. This talk will examine the advantages and
disadvantages of some of the new technologies developed to provide more robust, versatile, and sensitive measurements
of precision components for advanced manufacturing environments.
