Tool and die makers are highly skilled workers in the manufacturing industry. Tool and die makers make jigs, fixtures, dies, molds, machine tools, cutting tools (such as milling cutters and form tools), gauges, and other tools used in manufacturing processes. Depending on which area of concentration a particular person works in, he or she may be called by variations on the name, including tool maker (toolmaker), die maker (diemaker), mold maker (moldmaker), tool fitter (toolfitter), etc.
itionally, working from engineering drawings, tool makers marked out the design on the raw material (usually metal or wood), then cut it to size and shape using manually controlled machine tools (such as lathes, milling machines, grinding machines, jig borers, and jig grinders) and hand tools (such as files).

Job description
Traditionally, working from engineering drawings, tool makers marked out the design on the raw material (usually metal or wood), then cut it to size and shape using manually controlled machine tools (such as lathes, milling machines, grinding machines, jig borers, and jig grinders) and hand tools (such as files). Many tool makers now use computer-aided design , computer-aided manufacturing and CNC machine tools to perform these tasks.
Training
Although the details of training programs vary, many tool and die makers begin an apprenticeship with an employer, possibly including a mix of classroom training and hands-on experience. Some prior qualifications in mathematics, science, engineering or design and technology can be valuable. Many tool and die makers attend a 4- to 5-year apprenticeship program to achieve the status of a journeyman tool and die maker. Today's employment relationships often differ in name and detail from the traditional arrangement of an apprenticeship, and the terms "apprentice" and "journeyman" are not always used, but the idea of a period of years of on-the-job training leading to mastery of the field still applies.
Job outlook
Employment of tool and die makers is expected to decline in some countries due to increased use of automation, including CNC machine tools and computer-aided design,computer-aided manufacturing. On the other hand, tool and die makers play a key role in building and maintaining advanced automated manufacturing equipment.
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.
