Vector Group to Vector Group

Vector Group to Vector Group Relationships

Built with Shim and Gap applications in mind, as well as comparisons between sequential measurements, this Vector Group to Vector Group Relationship (VG to VG Relationship) computes a delta vector group defining the difference between two reference vector groups.

A VG to VG relationship offers the following property controls:

Proximity Settings define a cylindrical proximity zone that is used to control which vectors in the second group are used for comparison with the first.

Nominal Relative Polarity Between Vector Groups optional selection is used to control the mathematical comparison of the vector groups.

Gap Optimization evaluation Settings are used to both control the fit setting used in a relationship optimization and the default tolerances passed to the resulting vector group for reporting purposes.

The Gradient Steepness Factor defines the how a relationship will influence the fit as it enters the desired gap threshold. Unlike a fixed constraint which is either on or off, the gradient control provides a means to control the transition rate of the fit weight as it moves from the max or min weight toward the nominal weight.

If the tolerance is very narrow, then the gradient steepness value must be set quite large (~500), providing a sharp drop off in influence. If the gap tolerance is larger then the gradient steepness can be set smaller (~50) which produces a slower transition.

Basic shim and Gap application would go as follows:
