Part skew alignment
When the part is misaligned (twisted) in the X-Y plane, errors can be generated
during the measurement process. These errors can be eliminated by performing a
skew alignment on the part.
The skew alignment includes a precise measurement of the part misalignment.
Once the misalignment is known to the system, subsequent feature measurements
are automatically compensated to eliminate misalignment errors. Measurement
data in the DRO will reflect measurements of a perfectly aligned part.
To skew the part:
1 Touch the Measure tab and then touch the measure line icon.
2 Measure a line along the reference edge of the part. The X-axis
edge is used in this example.
3 Touch the Align button to
perform a skew on the reference
edge.
The skew line feature will now be shown in blue and the reference angle will be zero degrees.
