Kinematic coupling of disposable contact
Kinematic coupling describes fixturing based on geometric constraints. For example, three non-parallel groves in one part mate with three hemispheres in another. Each hemisphere has two contact points for a total of six contact points, enough to constrain all six of the part’s degrees of freedom.
