Jigs & Fixtures
“Jig” and “Fixture” are often referred to as synonyms, while sometimes both are used together as jigs-fixtures. Although both jig and fixture are used in the mass production process, functionally, the two are quite different tools.
Let us go through the main points which differ a Jig from a fixture.
Let us go through the main points which differ a Jig from a fixture.
| Jigs | Fixtures |
|---|---|
| A jig controls and guides the machining tool | A fixture holds and supports the component precisely for machining operations |
| Jig ensures accuracy, repeatability, and interchangeability | The fixture provides a reduction in error by holding a component firmly on a table |
| Jigs are usually on the lighter side | The fixture is bulky, rigid, and heavy |
| Jigs can be put in place and held by hand pressure | Fixtures are always placed firmly on a machine table |
| Some of the standard jig functions are drilling, reaming, tapping, and boring | Fixtures are used explicitly in milling machines, slotting machines, and shapers |
| Jigs cost more | Fixtures are not that cost-savvy compared to Jigs |
| Jigs require intricate design operations | Fixture design operations are relatively less complicated |
