An example of a jig is when a key is duplicated; the original is used as a jig so the new key can have the same path as the old one.

Jigs may be made for reforming plastics.

A common type of fixture, used in materials tensile testing (Grip-Engineering). A fixture is a work-holding or support device used in the manufacturing industry. [1] [2] Fixtures are used to securely locate (position in a specific location or orientation) and support the work, ensuring that all parts produced using the fixture will maintain conformity and interchangeability.
A well-designed trellis frame should provide a strong, lightweight structure that simplifies placement of engine and components, and gives good access for maintenance. Although construction of a trellis frame needs a more complicated process than, say, an alloy beam frame, it requires only a simple jig and a competent welder. No heavy capital ...
Failure to use a suitable fence or jig can result in injuries, such as those caused by kick-back. [3] [4]: 121–125 The most common fence on a table saw is a rip fence, and is provided as standard with any new table saw. The rip fence is parallel to the saw blade and can be adjusted to different distances from the blade to set the size of the ...
