Negative-Stiffness Vibration Isolation
Improves Laser Interferometry Performance in Precision Surface Engineering
Excerpted from Commerical Micro Manufacturing
International - Septeber 2015
In
manufacturing, CMMs are used to test a part or assembly against the design
intent. By precisely recording the X, Y, and 2 coordinates of the target,
points are generated which can then be analyzed for the construction of
features. These points are collected by using a probe that is positioned, in
this circumstance via direct computer control (DCC), DCC CMMs can be programmed
to repeatedly measure identical parts. Hence, CMMs are a specialized form of
industrial robot.
Vibration Isolation
Critical These high-throughput CMM laser interferometry
surface measurement systems, however, can be negatively affected by plant
low-frequency vibrations. which can distort the interferometry measurements and
deliver inaccurate readings. One of these CMM systems, custom-designed
and manufactured for specific applications by Arnold Gauge Company, has
resolved the vibration issue. The company's CMM system maintains its precision
high throughput by integrating a unique, highly-compact Negative-Stiff ness
vibration isolation platform. "Every second, the laser in the CMM is
generating about 2,000 readings per second," said Michael Bruins, President of
Arnold Gauge Company. "These readings, taken at the micron level, are displayed
on a chart, plotted against the pre-engineered ideal surface. Due to
these micro tolerances, any vibrations, whatsoever, on the plant floor, such as
from forklifts, for example, are going to be detected in the readings, and will
negate the validity of the results. To counteract these vibrations, we selected
Negative-Stiffness vibration isolation. Laser-based interferometers
are extremely sensitive devices that are capable of resolving nanometer scale
motions and features. They often have very long mechanical paths which makes
them even more sensitive to vibrations. The sophisticated modern ellipsometry
techniques that allow this high performance rely on low noise to be able to
detect fringe movement. Properly isolating an interferometer will allow it to
provide the highest possible resolution. improved AFM performance. One
of these advances has expanded the AFM ability to image biological samples in
an aqueous buffer and provide a range of physical data for the sample.
Another has increased the imaging speed of AFMs. Unlike Scanning Electron
Microscopes, which are capable of scanning in near real-time, conventional
AFMs, prior to about five years ago, required between one and 100 minutes to
obtain a high-resolution image. With the introduction of high-speed AFM
systems, imaging speeds are three orders of magnitude faster than with previous
AFMs. The

Minus K Continues
Educational Giveaway Minus K has again
launched their educational giveaway for their negative-stiffness vibration
isolators for colleges/univerities within the United
States.
Any college/university within
the United States, that has an AFM, Electron Microscope, Interferometer, Laser
Optical System, Micro Hardness Tester, or any other special equipment that
would benefit from a low-frequency vibration isolator can apply. No purchase
necessary. The
submission forms will be
judged by the Educational Giveaway Committee on multiple catagories.Limited to one submission per college
department. Submission deadline for applications
is February 29, 2016.
The
selected college departments will be notified by March 31, 2016 and posted on
Minus K's website. A new FREE Minus K vibration isolator
will be shipped within one month of notification.
Minus K will conduct a brief interview with
the selected departments six months after receiving their isolator. The
interviews will be used to learn how vibration isolator helped with the
application goals and interview may be used for articles in industry
publications.
Congratulation to the
education giveaway winners:
Purdue University –
Chemistry Department Vibration isolator for use with their
custom-built scanning tunneling microscope (STM). (The major research
thrust of their group is the design of custom scanning probe instrumentation
that provides structural resolution within single molecules at the
sub-nanometer scale.)
Willamette University - Physics
Department Vibration isolator for use to frequency down-conversion
of 846 nm light to 423 nm light in a home-built bow-tie cavity using a BiBO
nonlinear crystal. The 423 nm light will be used to cool and trap calcium
atoms. (The long term goal of this project is the generation of ultracold
dipolar dimers consisting of one rubidium and one calcium atom. One exciting
application of these molecules is their potential use in quantum
computation.)
