 Manufacturing
in the 21st century requires knowledge in many areas, including structural
dynamics, optics and photonics, precision design, heat transfer,
and metrology (‘the science of measurement’), in order to
develop process models and improve efficiency. An important example is
the
increased use of high-speed machining to produce discrete components
in the aerospace,
automotive, and biomedical industries. To reduce machining
time, high speed/power spindles are combined with high velocity/acceleration
motion bases to allow the tool to traverse
the part path in minimal time. A primary process limitation is chatter,
or unstable machining that results in large forces and vibrations. To
avoid chatter, pre-process predictions of Other research areas include: 1) measuring displacements using heterodyne laser interferometry; 2) evaluating the uncertainty for optical and structural dynamics measurements; and 3) applying decision theory to milling optimization. Educational contributions include the development of a series of video segments (Pigskin Professor) describing engineering using football terminology shown during the 2003 UF home football games and used for UF College of Engineering student recruiting.

stable machining conditions
can be made provided the system dynamics are known. Current work includes
the development of a method, Receptance Coupling Substructure Analysis,
to model the machine assembly dynamics.
