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.
What they do:
Set up and operate a variety of machine tools to produce precision parts and instruments out of metal. Includes precision instrument makers who fabricate, modify, or repair mechanical instruments. May also fabricate and modify parts to make or repair machine tools or maintain industrial machines, applying knowledge of mechanics, mathematics, metal properties, layout, and machining procedures.
On the job, you would:
Calculate dimensions or tolerances, using instruments, such as micrometers or vernier calipers.
Machine parts to specifications, using machine tools, such as lathes, milling machines, shapers, or grinders.
Measure, examine, or test completed units to check for defects and ensure conformance to specifications, using precision instruments, such as micrometers.
