Using Part Matching to Accept or Reject a Part
Part matching results only determine whether a measurement is applied to a part. Whether the
measurement returns a pass or fail value—its decision—depends on whether the measurement's value
is between the Min and Max values set for the measurement. This decision, in addition to the actual
value, can in turn be used to control a PLC for example. The part matching "decision"itself is not passed
to the Gocator output, but you can simulate this by setting up a measurement that will always pass if it is
applied.
For example, you could set up a Position Z measurement, choosing Max Z as the feature type, and
setting the Min and Max values to the measurement range of the sensor.This way, as long as a part
matches and the target is in range, etc., the measurement will pass. This measurement decision, which is
passed to the Gocator's output, could in turn be used to control a PLC.
Sections
In Surface mode, Gocator can also extract a profile from a surface or part using a line you define on that
surface or part. The resulting profile is called a “section.” A section can have any orientation on the
surface, but its profile is parallel to the Z axis.
You can't create sections on surface data that is produced by other tools, such as Surface Stitch.
You can use most profile measurement tools on a section: you can't use tools that work with
unresampled data. Using sections and the profile measurements, you can therefore use measurements
that are not otherwise possible in Surface mode, for example:
l Gap and flush measurements
l Surface radius measurements (for example, rounded edges or corners)
l Intersections
l Point-to-point dimension measurements between profile features
Gocator supports multiple sections, letting you take multiple measurements on the same object.
On the Output page, in Surface mode, you can output both surface measurements and section-based
profile measurements at the same time. Gocator can also output the surfaces and section profiles
themselves at the same time.
