They also produce jigs and fixtures—devices that hold metal while it is bored, stamped, or drilled—and gauges and other measuring devices. Jigs, fixtures and gages are needed to maintain quality standards for repeated low and high volume production demands.
Like the dies, the presses range in size from extremely small to gigantic. There is often turnover between the careers, as one person may end up working in both at different times of their life, depending on the turns of their particular educational and career path.
Ensuring high-quality tooling requires a wide range of factors to be considered. As engineers design and build new types of machine tools, machinists must learn new machining properties and techniques. 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.

Jigs and fixtures can be as big as a car or be held in hand. Candidate will Eventually, some machine shops began to specialize in tooling to the exclusion of other work. Dies are used to shape metal in stamping and forging operations.
For the vacuum forming of plastic sheet only a single form is used, typically to form transparent plastic containers called blister packs for merchandise. Some machinists repair or make new parts for existing machinery.
