What They Do
Machinists and tool and die makers set up and operate a variety of computer-controlled and mechanically controlled equipment to produce precision metal parts, instruments, and tools.
Duties
Machinists typically do the following:
- Read detailed drawings or files, such as blueprints, sketches, and those for computer-aided design (CAD) and computer-aided manufacturing (CAM)
- Set up, operate, and disassemble manual, automatic, and computer numerically controlled (CNC) machine tools
- Align, secure, and adjust cutting tools and workpieces
- Monitor the feed and speed of machines
- Turn, mill, drill, shape, and grind machine parts to specifications
- Verify that completed products meet requirements
Tool and die makers typically do the following:
- Read detailed drawings or files—such as blueprints, sketches, specifications, and those for CAD and CAM—to make tools, molds, and dies
- Compute and verify dimensions, sizes, shapes, and tolerances of workpieces
- Set up, operate, and disassemble conventional, manual, and CNC machine tools
- File, grind, and adjust parts so that they fit together
- Test completed tools and dies to ensure that they meet specifications
- Smooth and polish the surfaces of tools and dies
Machinists use lathes, milling machines, grinders, and other machine tools to produce precision metal parts. Many machinists must be able to use both manual and CNC machinery. CNC machines control the cutting tool speed and do all necessary cuts to create a part. The machinist programs instructions into the CNC machine to determine the cutting path, cutting speed, and feed rate.
Although workers may produce large quantities of one part, precision machinists often produce small batches or single items. The parts that machinists make include steel bolts, titanium bone screws, and automobile pistons.
Some machinists repair broken parts or make new parts that an industrial machinery mechanic discovers in a machine. The machinist refers to engineering drawings to create the replacement.
Some manufacturing processes use lasers, water jets, and electrified wires to cut the workpiece. As engineers design and build new types of machine tools, machinists must learn new machining properties and techniques.
Tool and die makers construct precision tools or metal forms, called dies, that are used to cut, shape, and mold metal, plastics, and other materials.
Tool and die makers use CAD to develop products and parts. They enter designs into computer programs that produce blueprints for the required tools and dies. CNC programmers, described in the metal and plastic machine workers profile, convert CAD designs into CAM programs that contain instructions for a sequence of cutting-tool operations. Machinists normally operate CNC machines, but tool and die makers often are trained to both operate CNC machines and write CNC programs and thus may do either task.
Work Environment
Machinists held about 299,500 jobs in 2024. The largest employers of machinists were as follows:
| Fabricated metal product manufacturing | 34% |
| Machinery manufacturing | 21 |
| Transportation equipment manufacturing | 13 |
| Wholesale trade | 4 |
| Employment services | 3 |
Tool and die makers held about 55,200 jobs in 2024. The largest employers of tool and die makers were as follows:
| Transportation equipment manufacturing | 26% |
| Machinery manufacturing | 23 |
| Fabricated metal product manufacturing | 20 |
| Plastics product manufacturing | 7 |
| Primary metal manufacturing | 7 |
Injuries and Illnesses
Because machinists and tool and die makers may work with machine tools that present hazards, these workers must take precautions to avoid injuries. For example, workers must wear protective equipment, such as safety glasses to shield against bits of flying metal and earplugs to dampen the noise produced by machinery.
Work Schedules
Many machinists and tool and die makers work full time during regular business hours. However, some work nights and weekends in facilities that operate around the clock. Some work more than 40 hours a week.
How to Become One
Although machinists typically need a high school diploma to enter the occupation, tool and die makers also may need to complete postsecondary courses. Machinists and tool and die makers typically are trained on the job. Some learn through training or apprenticeship programs, vocational schools, or community and technical colleges.
Pay
The median annual wage for machinists was $56,150 in May 2024.
The median annual wage for tool and die makers was $63,180 in May 2024.
Job Outlook
Overall employment of machinists and tool and die makers is projected to grow 2 percent from 2024 to 2034, decline.
About 34,200 openings for machinists and tool and die makers are projected each year, on average, over the decade. Many of those openings are expected to result from the need to replace workers who transfer to different occupations or exit the labor force, such as to retire.
