Equator's innovative and highly repeatable gauging
technology is based on the traditional comparison of
production parts to a reference master part.
Re-mastering is as swift as measuring a production part
and immediately compensates for any change in the
thermal conditions of a shop-floor environment. Equator
can be used in factories with wide temperature variation
– simply re-master and the system is ‘re-zeroed', ready
for repeatable comparison to the master.
Master parts do not need to be expensive custom parts
like a traditional gauge; take a production part and
measure it on a co-ordinate measuring machine (CMM) to
establish feature variation from CAD or drawing
nominals. The results from any CMM, operating with any
CMM programming software, can be configured to be used
directly within the Equator software.
Effectively, the calibrated absolute accuracy of the CMM
(often located in remote temperature controlled rooms to
ensure accuracy) can be ‘extended' onto the shop floor to
provide calibrated traceability to Equator measurements.
With the calibration file loaded into the Equator software,
measurements made in the Equator system can be referred back
to the CAD or drawing nominals. This allows true process
control with SPC packages.
A known good part, or 'master' part, is scanned to generate
a master data set. The same scanning routine is applied to
each of your production parts. Each production data set is
compared to the master data set to determine whether the
associated part is within user defined tolerances.
Determining the nominal size of your production parts is
also possible. Simply measure the master part on a CMM to
create a calibration data set to normalise your subsequent
comparisons. Now the true deviations from part nominal can
be displayed for each part.
