Gage-It I™


Gage-It I™

A functional gage for use with Geo-Fact IT, consisting of a base, a spring loaded rear fence with three detent positions for special applications, a removable side fence, three removable gage pins with four Material Condition expansion sleeves, four pivoting tombstones, three coordinate system axes, and six tooling balls. Gage-It I serves to demonstrate over 25 DRF construction alternatives, a myriad of tolerancing concepts, and the Simultaneity Rule.

Materials: Delrin, Anodized Aluminum, Stainless Steel

Price: $2150.00

The Gage-It I serves to illustrate:

  1. The difference between Datum Features, Datum Feature Simulators and Datums
  2. Datum Reference Frame construction
  3. Datum Feature versus Datum Target based, Datum Reference Frame construction
  4. Datum Feature Competition and the Sullivan-Tandler Degrees of Constraint Matrix
  5. Material Free Boundary Concept (Virtual Condition)
  6. Material Filled Boundary Concept (Resultant Condition)
  7. Unconstrained, Orientation Constrained, and Location Constrained Actual Mating Envelopes
  8. Effects of Datum Feature Simulator size control
  9. Effects of Datum Feature Simulator location control (an important, often overlooked effect)
  10. The Rule of Datum Feature Precedence
  11. The Rule of Degrees of Constraint Precedence
  12. The Rule of Non-Override
  13. The Rule of Maximum Utilization
  14. The Rules of Simultaneous Requirements
  15. The 6 Step Datum Reference Frame construction process
  16. Datum Reference Frame / Tolerance Zone Mobility effects
  17. The impact of imperfect geometry on machining and inspection operations

And much more.
