Modular fixture design for generalized polyhedra
نویسندگان
چکیده
The term xturing refers to the task of immobilizing a workpiece for the purpose of performing operations such as assembly and machining. As such, xturing is of fundamental importance to industrial manufacturing. Fixtures can either be fabricated from scratch, or assembled from a toolkit of modular components, the latter approach is termed modular xturing. In this paper, we present a complete algorithm to automatically design xtures for the xture vise toolkit. The algorithm enumerates xture con gurations, consisting of peg positions, workpiece pose, and jaw separation, for a given generalized polyhedral workpiece. A generalized polyhedral prismatic workpiece is de ned to have a generalized polygonal silhouette, with a boundary composed of linear edges and circular arcs.

On the Existence of Solutions in Modular Fixturing
A fixture is a device that locates and holds parts during machining or assembly. A modular fixture employs reusable components on a regular lattice. Given a part, machinists combine intuition with trial-and-error to design an appropriate fixture. When a machinist is unable to find a design, it may be the case that (1) a feasible design was overlooked or (2) no feasible design exists. Complete a...
متن کاملOn the Existence of Modular Fixtures
Modular fixtures are gaining wide use for flexible manufacturing and job shop machining. A modular fixture is an arrangement of fixture elements (fixels) that will locate and securely hold a given part. Typically, a human combines intuition with trial-and-error to design fixtures. In some cases designers are unable to design a fixture with given fixels and must resort to custom tooling. It is p...
متن کاملDevelopment of Automated Dedicated Fixture Configuration Design Systems with Predefined Fixture Component Types: Part 1, Basic Design
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...
متن کاملFixture Design System with Automatic Generation and Modification of Complementary Elements for Modular Fixtures
Modular fixtures are usually built from standard elements that can be found in the modular element set of a certain manufacturer. But in some cases the user besides using these elements modifies some semi-finished elements that can also be found in the modular element set, or even the user produces some brand new elements. The motivation behind this can be to simplify the fixture, or to make th...

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...
