Design Of Fixture

Introduction

Fixture is a workpiece-locating & holding device used along with machine tools. It is also used in inspection welding and assembly. Fixture doesn't guide the cutting tool but it is always fixed to machine/bench. By using fixture, responsibility for accuracy shifts from the operator to the construction of machine tool.

While some parts are to be machined, workpiece clamp to the machine table without using fixture in several machining operations. Therefore, while the numbers of elements are large enough to justify its cost, a fixture is commonly used for holding & locating the work.
