(The data is reflected and the machine
parameter is updated)
●You can confirm the measurement accuracy result by re-measurement.
In that case, perform [Checking of measurement result] (→P.13-21-2-

Checking of measurement result
Cause Troubleshooting
The plane correction jig is
contaminated.
Check for any flaws or foreign bodies on the
surface of the jig.
Calibration jig is contaminated.
Check for any flaws or foreign bodies on the
surface of the jig.
If so, clean the surface with the provided brush and be careful not to
damage.
Machine parameters of the
inspection
head are wrong.
Execute calibration for the inspection head.
Verifies the results registered as offsets in “Checking and reflection of measurement” The procedure is the
same as the one used in “Checking and reflection of measurement”
Though not necessarily required, this procedure will be used as a guideline for measuring the level of
accuracy of the machine.
●As for MCDATA (production program), use accuracy verification MCDATA.
(→ P.13-21-1
-7 ‘■MCDATA type’)
●Accuracy verification MCDATA is intended for accuracy verification use, so refrain from reflecting in it the
each-position-angle offsets obtained from measurement results.
(→ P.13-21-1
-7 ‘■Reflection of verification data’)
The following causes are cited as possible causes when no improvements are seen in accuracy verification
results.
