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 issues in the fixture layout design: 1...

Manufacturing and assembly processes often require objects to be held in such a way that they can resist all external wrenches. The problem of " xture planning" is to compute, for a given object and a set of xturing elements, the set of placements of the xturing elements that constrain all nite and in nitesimal motions of the object (due to applied wrenches). As xturing problems occur frequentl...

Fixturing, i.e. the process of immobilizing a work-piece for manufacturing or assembly operations, is a fundamental task in manufacturing. Fixtures can either be fabricated from scratch or assembled from a toolkit of modular components; the latter approach is termed modular xturing. Recently, many researchers have proposed generate and test xture design algorithms for minimal modular xture tool...

Fixture design is an important issue in the process of manufacturing. Fixture design is a critical design activity process which bridges Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM). The present paper presents a literature review of the Computer-Aided Fixture Design (CAFD) approaches performed. The purpose of this research is to give a deep and quick understanding of fixtu...

The design of a fixture depends a lot on the designer’s expertise and experience and hence no solution is optimal or near optimal for a given workpiece. For a Gear hobbing fixture also there are multiple designs possible. This paper is about redesigning of a hobbing fixture to make it common for the other gears’ manufacturing and reduce the no of settings of the fixture on the hobbing machine. ...

Various areas related to design of fixture are already been very well described by various renowned authors. This section reviews some of the developments in fixture design and proposes directions for future research initiatives.

The essential factor for the recent manufacturing companies is to develop a variety of products within short timeframes. Therefore, the flexible manufacturing techniques are rapidly growing to compete the markets globally. A number of factors contribute in organizational ability to achieve flexibility and one of which is the use of fixtures to increase the pace of production. A fixture is like ...

Near Optimal Design of Fixture Layouts in Multi-station Assembly Processes. (August 2004) Pansoo Kim, B.S., Pusan National University; M.S., Pusan National University Chair of Advisory Committee: Dr. Yu Ding This dissertation presents a methodology for the near optimal design of fixture layouts in multi-station assembly processes. An optimal fixture layout improves the robustness of a fixture s...
