Knowledge-Based Design of Jigs and Fixtures

Abstract

Jigs and fixtures are devices used in manufacturing processes such as machining, welding, bonding and assembly. They are employed to locate and hold the workpiece firmly in position and to ensure that it is in a state of stable equilibrium (geometric control) and that dimensional accuracy is maintained during the manufacturing operation (dimensional control). Jigs and fixtures are generally referred to as “fixturing systems” or simply “fixtures”.
