Exact Constraint : Machine Design Using Kinematic Processing, Hardcover by Blanding, Douglass L., ISBN 0791800857, ISBN-13 9780791800850, Brand New, Free shipping in the US Explains how to expand kinematic design from engineering precision instruments, a use well over a century old, to designing machines of any type and size. Reduces the principles of the approach into a set of rules and techniques that can be applied broadly. A central technique is Constraint Pattern Analysis, which enables a designer to visualize the constraints and degrees of freedom of a mechanical connection as patterns of lines in space. The lines turn out to obey rules that are fairly simple but not widely known. Annotation c. Book News, Inc., Portland, OR ()
