Different components of Jigs and Fixtures:

1. Body: It is a plate, box or frame type structure in which the components to be machined are loaded. It should be quite sturdy and rigid.

2. Locating Elements: These elements position the work piece firmly in the proper position against the action of cutting forces.

3. Clamping elements: These elements held the work piece firmly in located Position.

4. Guiding and Setting elements: In jig, the guiding element used is drill bush. It guides the cutting tool till the surface of work piece where hole is to be drilled. In fixtures, the setting element is setting block.

5. Positioning elements: These elements include different types of fastening devices which are used in securing the jigs and fixture to the machine at proper position.

6. Indexing Elements: Sometimes the work piece may have to be indexed to different position in order to perform machining operations at different locations. In such case indexing elements are to be used.
