—This paper describes an approach to optimal design of a fixture layout with the minimum required number of elements, i.e., six locators and a clamp. The approach applies to parts with arbitrary 3-D geometry and is restricted to be within a discrete domain of locations for placing the fixture elements of nonfrictional contacts. The paper addresses two major(More)
This paper addresses two major issues in fixture layout design: (1) to determine the feasible fixture configurations that satisfy fundamental requirements such as kinematic localization and total fixturing (form-closure) and (2) to evaluate the acceptable fixture designs on several quality criteria and select the optimal fixture appropriate with practical(More)
— The conventional point-kinematic model of fixtures has only treated point geometry of the contacts between locators and workpiece. However, this model, which ignores the underlying surface properties of the locators-plus-workpiece system, is inherently incapable of capturing the effects of the geometric properties important to accurate positioning of the(More)
