let's talk about the challenges of
portable CMM technology portable CMMS
are most often used in shop floor
environments where permanent vibrations
are generated by production equipment
and where operators experience and level
of skills may vary they are also used
for the requirements for rigid equipment
setups are complex and where changes in
temperature and humidity levels often
occur all of these will considerably
impact measurement accuracy over the
past 30 years companies in a wide
variety of industries have been looking
to increase product quality and
productivity that is why portable CMMS
have brought inspection right into the
production line but can conventional CMM
stand up to the challenge of measurement
conditions that are far from the comfort
of metrology labs where qualified
inspectors operate digital CMMS with
their heavy stable granite tables a lab
based experiment which was presented
recently at a CMS conference reproduce
shop floor vibrations the experiment
compared results between the
conventional articulated arm and an
optical portable CMM that featured
dynamic referencing the handyprobe in
the lab environment where there are no
vibrations
the handyprobe and the articulated arm
had the same accuracy however with a
simulation of the typical vibrations of
a production environment the level of
accuracy was three times lower with the
articulated arm than with the handyprobe
this level of error can generate serious
consequences in product quality and
overall production ROI during that same
conference another measurement study was
conducted with measurement experts who
had been working in the quality control
and inspection field for over seven
years the results showed that 94% of the
participants did not pay attention to
the stability of the park furthermore 7%
of the participants moved apart without
noticing after aligning it resulting in
errors of several millimeters
both vibrations and human error can
severely impact on measurement accuracy
which in turn can generate multiple
costs and slow down productivity thanks
to optical portable CMMS like the
handyprobe companies can avoid these
major issues and ensure a top level and
systematic product quality see the
