To build everything
workshops and factories around
the country rely on the handiwork of
machinists, and tool and die makers.
Starting from blueprints, sketches,
or computer-aided design files, they set up
the machines that produce parts.
Once products are made,
they file and grind them to
meet project specifications,
giving them a final smoothing and polish to finish.
Machinists run computer numerically controlled
or CNC—machines…
that produce precision metal parts and tools.
They may produce a large number of one part–
such as automobile pistons…
or many small batches—
like bone screws for medical implants…
or even one-of-a-kind items.
They need to be skilled with a
wide range of machines and techniques.
Toolmakers craft precision tools
for cutting and forming metal,
and create different gauges
and other measuring devices.
Die makers construct metal forms
used to shape metal, and make
molds for shaping plastics,
ceramics, and composite materials.
Tool and die makers are trained to
write CNC programs as well as
operate the machines.
Workers wear safety glasses,
earplugs, and masks when needed
to protect themselves during
hazardous phases of their work.
Schedules are generally full time,
with some shifts on evenings
and weekends to keep production
running around the clock.
A high school diploma or equivalent
is necessary, and skills in math
and problem-solving are important.
Machinists may train in
on the job, apprenticeship,
or at technical colleges.
Becoming a tool or die maker
takes several years of instruction
and on-the-job training.
