Jigs and Fixtures: Types, Parts, Definition, Applications ...

jigs and fixtures are the devices which help in increasing the rate of identical parts and reducing the human efforts required for producing these parts, It has already been emphasized earlier that a center lathe is a suitable machine tool for producing individual parts of different shapes and sizes, but for producing similar articles in great number its use will not be economical. Against this, a capstan and turret lathecan be easily adapted for repetition work on account of the multi cooling arrangement and use of transverse stop this increases the rate of production. However, every type of object cannot be machined on a capstan or turret lathe and may involve the use of drilling, milling, planning and grinding machines,etc. If such objects are to be produced in identical shapes and sizes on a mass scale, suitable devices have to be used for holding and locating purposes so that the repetition work can be done. These devices are the jigs and fixtures.

Main elements of jigs and fixtures are: Body:It is a plate, box or frame type structure in which the components to be machined are located. It should be quite sturdy and rigid. Locating elements:These elements locate the workpiece in a proper position in relation to the cutting tool. Clamping elements:These elements firmly secure the workpiece in the located position. Grinding and setting elements:These elements guide the cutting tool in case of jig and help in proper tool acting in case of the fixture. Positioning elements: These elements include different types of fastening devices,which are used in securing the jig or fixture to the machine at the proper position. Indexing elements:They are not provided always. But, many workpieces may have to be indexed to different positions in order to perform machining operations on different surfaces or different locations. In such cases, these elements will have to be incorporated in the jig or fixture. Read also: Capstan and Turret Lathes

Following are the 10 different types of fixtures: 1. Turning fixtures. 2. Milling fixtures. 3. Broaching fixtures. 4. Grinding fixtures. 5. Boring fixtures. 6. Indexing fixtures. 7. Tapping fixtures. 8. Duplex fixtures. 9. Welding fixtures. 10. Assembly fixtures. Fixtures are usually named after the type of machining operation for which they are designed and employed.

The following are the fundamental difference between a fixture with a jig: 1. A fixture holds and position the work but does not guide the tool, whereas a jig holds, locates and as well as guide the tool. 2. The fixtures are heavier in construction and are bolted rigidly on the machine table, whereas the jigs are made lighter for quicker handling and clamping with the table is often unnecessary. 3. The fixtures are employed for holding work in milling, grinding, planing or turning operations, whereas the jigs are used for holding the work and guiding the tool, particularly in drilling reaming or tapping operations.

The following are the advantages of jigs and fixtures in mass production work. 1. Eliminates the making out, measuring, and other setting methods before machining. 2. It increases the machining accuracy because the workpiece is automatically located and the tool is guided without making any manual adjustment. 3. It enables the production of identical parts which are interchangeable. This facilitates the assembly operation. 4. It increases the production capacity by enabling a number of workpieces to be machined in the single set up, and in some cases, a number of tools may be made to operate simultaneously. The handling time is also greatly reduced due to the quick setting and locating of the work. The speed, feed and depth of cut for machining can be increased due to high clamping rigidity of jigs and fixtures. 5. It reduces the operators labour and consequent fatigue as the handling operations are minimised and simplified. 6. It enables a semi skilled operator to perform the oper...
