About Leap Sets
Leap Sets expand the capability
of your digitizer to collect features
from parts that are far larger
than the reach of your digitizing device. Leap Sets expand on the concept of datuming. With
datuming it is possible to
position and reposition a
digitizer to reach all sides
of a part, but only if those regions can be reached from digitizer
positions that can access the same set of reference geometry. Leap Sets provide the capability to work with far
larger parts because you can use
multiple positioning References. With
Leap Sets you are not limited to
reusing the same set of reference geometry to move you digitizer to a new
location. Like Datums, Leap Sets allow you to create and maintain a uniform coordinate system for the part being measured.
Leap Sets introduce the concept
of digitizer Stations and References. Stations are positions where digitizers
are physically located around the part to be digitized. References are sets of
geometry or jigs that are measurable from two or more stations to provide the information needed to accurately
move between stations. Because Leap
Sets are designed to allow the orchestrated movement of digitizers around parts,
they are primarily intended for use with portable articulated arm CMMs, not
stationary devices such as bridge CMMs.
The value of Leap Sets to make
digitizing large parts possible is tempered by the fact that some accuracy is
lost each time you move from one station to the next. Care must be taken to
minimize the inaccuracies that can creep into the data gathered through the Leap
Set mechanism.
