Jig/Fixture Maker

A jig and fixture maker is under the faction of a tool and die maker/toolmaker. The standard differentiation of jigs from fixtures is that a jig is what mounts onto a workpiece, whereas a fixture has the workpiece placed on it, into it, or next to it. The terms are sometimes used interchangeably. A jig and fixture maker needs to know how to use an assortment of machines to build these devices such as having skills in welding and in some cases the knowledge of wood working equipment, of course with the tool room machining skills.

Jig/fixture makers gain hands on practical experience while monitoring and making alterations as the manufacturing process is constantly improved and reviewed with/by engineering. They also can be required to make these adjustments without engineering help, depending on the size of the company.Some Jigs and fixtures require electronic and pneumatic actuation, which will involve knowledge/training in these fields as well.

Ongoing evolution of computerized design and control technologies, such as CAD/CAM, CNC, PLC, and others, has limited the use of jigs in manufacturing, however all the computer run machines need some sort of clamping fixture for production runs. A common example is that a drill jig is not needed to guide the drill bits to the hole centers if it is done on a CNC, since it is Computer Numerically Controlled. However, fixtures are still needed to hold the part(s) in place for the operation needed. Jigs are currently needed in many areas of manufacturing but mainly for low-volume production.
