In the 21st century, Manufacturers will increasingly face frequent and unpredictable market changes. These changes include the frequent introduction of new products, increased demand for new products and new process technologies. To produce variety of product and suit to new processes automated/semi automated machine tools and fixture are required. In this paper present a fixture design for aut...

Genetic algorithm (GA) is proven to be a useful technique in solving optimization problems in engineering. Fixture design has a large solution space and requires a search tool to find the best design. Few researchers have used the GAs for fixture design and fixture layout problems. Either separately (Kulankara et al 2002) or along with FEM, GA has been used for fixture layout and clamping force...

Due to rapid changes in recent market demands, shortened production ramp-up/launch and model changeover of new products with simultaneous manufacturing of family of products on a single production line is becoming inevitable. This requires systematic methods for rapid design and analysis of reconfigurable fixture workspace synthesis and visibility. This paper presents an integrated approach for...

This paper present a fixture design system of eccentric shaft for ginning machine.. Fixture is required in various industries according to their application. Designer design fixture according to dimension required by industry to fulfill our production tar gate. In traditional manufacturing process performing operation on eccentric shaft is critical. so holding a work piece in proper position du...

OBJECTIVE To investigate microbiological biofilm contamination of retrieved bone-anchored hearing aids. MATERIALS AND METHODS Nine failed, retrieved bone-anchored hearing aids and 16 internal screws were examined by scanning electron microscopy. A fixture from a failing implant, which had been removed and disassembled under aseptic conditions, was cultured. Finally, an internal screw from a n...

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...

Fixtures are used to locate and hold parts during automated inspection, machining, or assembly. Microelectromechanical systems (MEMS) are tiny devices built in batch processes derived from integrated circuit fabrication. We describe a design for an array of MEMS microfixtures for parallel inspection, transport, and assembly of microfabricated parts. In a microfixture array, parts are brought ne...
