Precision: The Synergistic Power of Inertia Mass and Pneumatic Air Isolators in
Cradle CMM Vibration Isolation System
The
incorporation of inertia mass in conjunction with pneumatic air isolators plays
a pivotal role in augmenting the vibration isolation of CMM (Coordinate
Measuring Machine), providing a multitude of advantages that greatly enhance
the precision, consistency, and dependability of measurements.
This
combination synergistically enhances vibration absorption, stability,
resistance against resonance effects, and the overall performance of the
isolation system in precision measurement conditions.
Coordinate
Measuring Machines (CMM) are widely employed in various industries, including
manufacturing, automotive, medical device manufacturing, electronics and
semiconductor manufacturing, precision engineering and tooling, research and
development, quality control and inspection, and metrology. Their primary
purpose is to verify the dimensional accuracy of manufactured components.
Dynemech
Pneumatic Isolators, DMAS series, with self-levelling
Pneumatic isolators are specifically engineered and extensively employed to
reduce the transmission of vibrations from the surrounding environment to the
CMM.
The working principle
·pneumatic
isolators use air pressure to generate a cushioning effect between the
coordinate measuring machine (CMM) and the supporting structure. This
successfully isolates the CMM from external vibrations, preventing their
transmission.
·DMAS Series
pneumatic isolators have air chambers that absorb and dissipate vibrations.
These pneumatic isolators serve as a low friction interface, enabling the CMM
to float on a heavily damped medium.
Frequency Range:
·Pneumatic
isolators, DMAS series, effective at both lower and higher frequencies (The
isolation starts typically above 2.5 Hz).
·However,
they provide limited isolation at lower
frequencies (below 2.5 Hz).
·At
frequencies close to their resonance frequency, they amplify vibrations ,
around 1.5 Hz
Inertial mass:
Purpose : Addition of the inertial mass
to the CMM structure strategically improves its stability and decrease its
susceptibility to external vibrations.
Mechanism:
·By
increasing the mass of the Coordinate Measuring Machine (CMM), its sensitivity
to rapid vibrations or disturbances is reduced. Essentially, it opposes changes
in acceleration due to its inertia.
·By lowering
the total centre of gravity of the CMM isolator system, it decreases the
system's inclination to oscillate at resonant frequencies.
·The
suspended cradle frame effectively manages the rotational and rocking
vibrations by aligning the vertical centre of gravity of the isolated CMM
system with the centreline of the isolator.
·By
increasing the mass of the vibration isolation system, the natural frequency of
the system is reduced, hence improving its capacity to successfully isolate
low-frequency vibrations found in the precision measurement environment.
Impact: The inclusion of additional mass reduces the intensity of
vibrations, leading to enhanced precision and repeatanility in measurements. It
serves as a protective barrier against external influences. An inertia base
serves as a rigid and stable support for the isolated equipment to be placed
on.
Combined Impact on CMM Vibration
Isolation:
1.Enhanced Vibration Absorption and Stability:
The integration of air
isolators with inertia mass results in a very efficient vibration isolation
system capable of successfully absorbing and dispersing vibrations over a broad
spectrum of frequencies. The air isolators offer exceptional isolation for
vibrations with high frequencies, while the inertia mass improves the system's
effectiveness in the low-frequency range.
2 . Resilience Against Resonance Effects:
Resonance
effects have the potential to disturb measurement procedures and result in inaccuracies in CMM readings. The integration of inertia mass with pneumatic isolators aids in reducing these effects by adding
extra mass to counterbalance vibrations caused by resonance. This
resilience ensures that the CMM remains unaffected by resonance, resulting in
more reliable and consistent measurement outcomes.
3.
Broadened Frequency Range:
The inclusion of both inertia mass and pneumatic
air isolators increases the range of frequencies at which the isolation system
may effectively reduce vibrations. Consequently, the CMM is capable of
functioning in a wide range of production settings that have different
vibration characteristics, guaranteeing reliable protection from external
disruptions.
4. Improved Accuracy,
Repeatability, and Reliability:
The integration of inertia mass with Dynemech pneumatic air isolators
efficiently isolates the CMM from external vibrations, ensuring that the
highest standards of dimensional accuracy are maintained. The minimized
transmission of vibrations reduces distortions and positioning errors, ensuring
that the sensors and probes of the CMM can accurately and consistently record
measurements.
To summarize, inertial mass enhances stability and decreases sensitivity to
oscillation, while pneumatic isolators mitigate vibrations and safeguard the
CMM from external disruptions. By utilizing the concepts of additional mass and
air cushioning, Dynemech engineers can successfully isolate CMM systems from
external disturbances, guaranteeing the precision and dependability of their
measurements, ushering in a new era of meticulous engineering.

element. It provides a stable support to the
precision measuring machines while minimizing the effects of shock and
vibrations, ultimately enhancing the performance of the equipment.
Membrane Air Spring used exhibits a low
natural frequency in the range of 1-1.5Hz. The machine payload is suspended on
the air through the flexible elastomeric membrane and damps most of the
incoming vibrations. The self-levelling arrangement ensures that
the top platform always remains levelled during the load changes on top of the
platform. The supplied air pressure may be varied depending upon the weight of
the equipment. A continuous air supply (not included) will
be needed to compensate for the load difference on the platform. The air is
either added or removed from the air spring to maintain the level of the top
surface.
