Both hold the workpiece. But a jig guides the cutting tool whereas a fixture does not.

1. Size

Jigs are normally very light in size and they are not fixed onto the machine table. This is because it has to move around guiding the cutting tool unlike the fixture that is clamped onto the table. Furthermore, the fixture is quite bulky in construction and it helps hold the work in position. The other reason why the fixture is fasted onto the table is to ensure that the work piece does not move when the machine starts operating.

2. Application

Fixtures boast of a wider application range as compared to jigs. In fact, fixtures are made for applications wherein the cutting machines cannot be easily guide like a drill. When using these work holders, a center finder, gauge blocks or edge finder positions the cutter. Some of the examples of common fixtures include lathe fixtures, milling fixtures, grinding fixtures and sawing fixtures. Furthermore, fixtures can be utilized in any machine operation that demands an exact relationship between a tools' position to a work piece.

3. Accuracy

Another key distinction between a jig and a fixture lies in accuracy. Here, a jig is more accurate than a fixture. In fact, jigs are typically used so as to ascertain the high precision of parts during production. This action helps control the quality control costs.

To sum up, jigs and fixtures help to save labor and even less skilled workforce can effectively work complex machines through their assistance.
