Fixture design is crucial part of manufacturing process. Fixture design is a critical design activity process, in which automation plays an integral role in linking computer-aided design (CAD) and computer-aided manufacturing (CAD). This paper presents a literature review in computer aided fixture design (CAFD) in terms of automation and optimization techniques over the past decades. First, the...

Although various computer-aided fixture design (CAFD) systems have been developed to assist the designer during the various stages of fixture design, most of previous computer aided fixture design research has mainly concentrated on machining fixtures rather than welding fixtures. The development of complicated computer aided welding fixture design (CAWFD) system has received much less attentio...

Designing a fixture layout is the primary task of fixture design, which consists of determining the different combinations of locators and clamping scheme. Designing a fixture is a lengthy process and the performance of a fixture is usually difficult to predict. Designing fixture to effectively restrain complex components has been recognised as a bottleneck in fixture design development. The ai...

An automated modular fixture design system has been developed in our previous study. Since dedicated fixtures are commonly used in mass production, in this research, a technique of automated dedicated fixture configuration design is studied with predefined fixture component types. The design methodology is divided into two stages: basic design and detail design. The basic design activities incl...

This chapter introduces an agent-based framework for engineering design of fixture systems. A number of researchers have applied the agent technology to engineering design and several agent-based systems have been developed accordingly addressing different application domains in design. Development of multi-agent system for fixture design is motivated by the need for a computational infrastruct...

Presents article is deal with optimization of the fixture for end milling process, the most important objective being the minimization of work piece deformation by changing the layout of fixture elements and the clamping forces. The main objective of this work has been the optimization of the fixtures Work piece deformation subjected to clamping forces for End milling operation. The present ana...

Fixtures are used to locate, hold and support workpieces in manufacturing operations such as machining, inspection, and assembly. Researching the possibilities for fixture design optimization has been in the sphere of interest of a number of authors worldwide for a longer period. Fixture design process and fixture design technique with conventional methods have been obsolete. Genetic Algorithm ...

A fixture is a mechanism used in manufacturing to hold a workpiece, position it correctly with respect to a machine tool, and support it during machining. Typically, fixture design involves the identification of clamp, locator, and support points, and the selection of corresponding fixture elements for their respective functions. The automation of fixture design activities in manufacturing is a...

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...
