Similarity and Differences Between Jigs and Fixtures

Jig and fixtures commonly called together have a small difference but large in their combined applications. 

Jigs

A jig is a work-holding device that holds, supports, and locates the workpiece and guides the one or more tools to perform a specific operation. In other words, this can also be defined as something that is used for holding the tools and also guiding the cutting tools. repeatability, accuracy, and interchangeability in the manufacturing of products are the main purpose of a jig. Certain points you should know about jigs are:

  • Until a large operation has to be performed jigs are not fixed to the machine table.
  • Processes like drilling, tapping, and reaming, etc. those are uni-dimensional machining processes that generally require jigs. 
  • Light and a complex shape is what jigs appear.
  • Jigs are expensive.
  • Gauge blocks are not necessary.

Fixtures

Very similar to Jigs, fixtures are also the work holding devices, which hold, support, and locate the workpiece but not guides the cutting tool to perform a specific operation. In other words, the fixtures are only the work holding a device that holds, supports, and locates the workpiece in the desired position to perform any operation.

Similarity and Differences

The nonproductive time of any mass production process is reduced with the use of both the jigs and the fixtures. Jigs as well as the fixtures are designed using the principle of location or the 3-2-1 principle, CAD tools (like ProE), and FEA tools (like ANSYS).

Unlike fixtures, Jigs come in contact with the cutting tool
