Precision Machine Design Articles

Precision machine design is the discipline of designing a device so it can hold a position, move to a position, or follow a position with a level of accuracy that is many orders of magnitude smaller than the size of the device itself. While traditional mechanical engineering is the domain of stress, precision machine design is the domain of deflection.

The Principle of Kinematic Constraint

The advantage of a kinematic mount is that it locates one rigid body relative to another with very high repeatability, without over-constraining the body or introducing instability. It accomplishes this by using the precise number (and arrangement) of contact points needed to allow the desired degrees of freedom – no more and no less. That is the principle of kinematic constraint, which this article will show how to apply in your designs.
