Jig maker

A jig maker is another term for a tool and die maker or fixture maker, usually in woodworking or in the metal industries. Actually a jig is what mounts onto a work piece, and a fixture has the work piece placed on it, into, or next to it. The terms are used interchangeably though throughout industry. A jig maker needs to know how to use an assortment of machines to build devices used in automation, robotics, welding, tapping, and mass production operations. They are often advised by an engineer to do the pre- planned work of building the much needed devices. In a production shop they need to know about an extensive assortment of machines, tools, and materials, and are often the most experienced toolmakers or woodworkers. They are often the ones who create from the original plans, the jigs, the fixtures and devices designed by and with the occasional assistance of the production engineer.

The reason jig makers need to be experienced is so that they can make suggestions for efficient alterations and needed repairs. They sometimes assist and monitor the progress of the jig or the fixture's gauging, locating, and innovative ability. Those who graduate to the level of jig and fixture makers often go on to gain automation skills, and the use of air, and electronic clamping procedures, and automation principles and equipment. They often need to know not only how to use basic machines to cut and machine steel and wood. For the most advanced, they need to be familiar with switches and the use of air supply equipment, various instruments, switches, hydraulic clamps, gauges, and more.

Properly built jigs and fixtures reduces waste, and produce perfect fitting parts, cutting out too much expensive hand work, mistakes and waste. Most are portable, and can be built or even moved throughout a facility. Some jigs and fixtures are as big as a car for placing a whole fender or chassis into them for assembly. It is how every volume shop works. The need for jigs and good gauging is necessary in furniture making for controlling quality and repeatability. A jig maker focuses on building tools in order to avoid placing parts incorrectly.
