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.
