Excessive machine tool vibration during a precision grinding operation can result in poor workpiece quality in the form of chatter, rough finishes, burn, etc. One possible reason for
excessive vibration is directly associated with the relationship
between natural frequencies of a machine tool system and the
operating speed of the grinding wheel spindle.
In a capitalist society, the way things usually work is that government
and academia focus on research and
development, while industry focuses
on commercialization. The result
is an increasingly wide disconnect in
the applied research sector, which deals
primarily with technology development
and demonstration.
More than 100 years ago, gear
manufacturers were facing
a significant challenge from
industry. The incredible advances in
industrialization and transportation that
occurred at the turn of the 20th century
resulted in incredible growth for gear
makers, but there were significant technical
issues. "The lack of process and product
standardization was a continuing
problem in all U.S. industry. The lack
of industry-wide gear standards meant
there were no standard gear tooth sizes,
ratings, quality definition or consistent
manufacturing methods" (Celebrating
100 Years of Gearing, pg. 22).
No, not that president! I mean Matt Croson, the new president
of the American Gear Manufacturers Association, who
started in June and has been busy getting to know the gear
industry and AGMA's members.
