Locate some previously recorded replay data and load it. See Recording, Playback, and Measurement Sim-
ulation on page 50 and Downloading, Uploading, and Exporting Replay Data on page 52 for more inform-
ation on replay data.
3. Go to the Model page.
a. Make sure the Enabled option is checked in the Part Matching panel.
b. In the Match Algorithm drop-down, choose Bounding Box or Ellipse.
4. Set Min and Max of both of the dimensions of the selected match algorithm shape, taking into account
expected acceptable variations.
l
If you chose BoundingBox for the match algorithm, select Width and then Length in Match Result, set-
ting the minimum and maximum values acceptable for each dimension.
l
If you chose Ellipse for the match algorithm, select Minor and then Major in Match Result, setting the
minimum and maximum values acceptable for each dimension.
5. Save the job by clicking the Save button .
See Creating, Saving and Loading Jobs (Settings) on page 48 for more information on saving jobs.
Running Part Matching
To run part matching, simply make sure that the Enabled option is checked on the Part Matching
panel when the Gocator is running. Any measurements that are added and configured on the Measure
page will be applied to parts if a part match is accepted, regardless of the part's orientation (a
successfully matched part is rotated to match orientation of the bounding box or ellipse), returning a
value and decision (as long as the part is in range, etc.). If a part match is rejected, measurements will
return anInvalid value.
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.
