the measurement took place in a relatively short time
interval.
These conditions ensured a minimal effect on the measurement. The
constant conditions did not affect the results of measuring.
According to the results in the previous section, it is possible to
compare the individual minimum widths of the tolerance field for
each measuring head.
One-side tolerance. The results for the fixed head VAST GOLD
show an upper tolerance limit of 39.9979 mm and a lower tolerance
limit of 39.9865 mm. This means that the width of the tolerance
field is 0.0114 mm. For the VAST XXT rotating head, the upper
tolerance limit is 39.9979 mm and the lower tolerance limit is
39.9941 mm. This means that the width of the tolerance field is
0.0038 mm.
Similar results are obtained for the bilateral width of the tolerance
field. The results for the VAST GOLD fixed head show an upper
tolerance limit of 40.001 mm and a lower tolerance limit of 39.991
mm. This means that the width of the tolerance field is 0.014 mm.
For the VAST XXT rotating head, the upper tolerance limit is
40.001 mm and the lower tolerance limit is 39.996 mm. This means
that the width of the tolerance field is 0.005 mm.
Based on these results, it can be said that the VAST XXT rotary
head has a tolerance field width 3 times smaller than the fixed
VAST GOLD head.
