Machinists typically use blueprints, sketches, or computer-aided design (CAD) and computer-aided manufacturing (CAM) files.
Machinists and tool and die makers set up and operate a variety of computer-controlled and mechanically controlled machine tools to produce precision metal parts, instruments, and tools.
Duties
Machinists typically do the following:
Read blueprints, sketches, or computer-aided design (CAD) and computer-aided manufacturing (CAM) files
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
Measure, examine, and test completed products for defects
Smooth the surfaces of parts or products
Present finished workpieces to customers and make modifications if needed
Tool and die makers typically do the following:
Read blueprints, sketches, specifications, or CAD and CAM files for making tools 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 properly
Test completed tools and dies to ensure that they meet specifications
Smooth and polish the surfaces of tools and dies
Machinists use machine tools, such as lathes, milling machines, and grinders, 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 determines the cutting path, the speed of the cut, and the feed rate by programming instructions into the CNC machine.
Although workers may produce large quantities of one part, precision machinists often produce small batches or one-of-a-kind items. The parts that machinists make range from simple steel bolts to titanium bone screws for orthopedic implants. Hydraulic parts, antilock brakes, and automobile pistons are other widely known products that machinists make.
Some machinists repair or make new parts for existing machinery. After an industrial machinery mechanic discovers a broken part in a machine, a machinist remanufactures the part. The machinist refers to blueprints and performs the same machining operations that were used to create the original part in order 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 form metal and other materials. They produce jigs and fixtures—devices that hold metal while it is bored, stamped, or drilled—and gauges and other measuring devices.
Dies are used to shape metal in stamping and forging operations. They also make metal molds for die casting and for molding plastics, ceramics, and composite 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. Computer numeric control 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. Once these programs are developed, CNC machines follow the set of instructions contained in the program to produce the part. 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.
Some machinists and tool and die makers work evenings and weekends because facilities may operate around the clock.

Injuries and Illnesses
Because machinists and tool and die makers work around machine tools that may present hazards, these workers must follow precautions to avoid injuries. For example, workers must wear protective equipment, such as safety glasses, to shield against bits of flying metal, earplugs to dampen the noise produced by machinery, and masks to limit their exposure to fumes.
Work Schedules
Although many machinists and tool and die makers work full time during regular business hours, some work evenings and weekends because facilities may operate around the clock. Some work more than 40 hours a week.
Machinists and tool and die makers typically are trained on the job.
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. Although machinists typically need just a high school diploma, tool and die makers may need to complete courses beyond high school.
Education
Machinists typically have a high school diploma or equivalent, whereas tool and die makers may need to complete courses beyond high school. High school courses in math, blueprint reading, metalworking, and drafting are considered useful.
Some community colleges and technical schools have 2-year programs that train students to become machinists or tool and die makers. These programs usually teach design and blueprint reading, the use of a variety of welding and cutting tools, and the programming and function of computer numerically controlled (CNC) machines.
Training
There are multiple ways for workers to gain competency in the job as a machinist or tool or die maker. One common way is through long-term on-the-job training, which lasts 1 year or longer.
Trainees usually work 40 hours per week and take additional technical instruction during evenings. Trainees often begin as machine operators and gradually take on more difficult assignments. Machinists and tool and die makers must be experienced in using computers to work with CAD/CAM technology, CNC machine tools, and computerized measuring machines. Some machinists become tool and die makers.
Some new workers may enter apprenticeship programs, which are typically sponsored by a manufacturer. Apprenticeship programs often consist of paid shop training and related technical instruction lasting several years. The technical instruction usually is provided in cooperation with local community colleges and vocational–technical schools. Workers typically enter into apprenticeships with a high school diploma or equivalent.
Licenses, Certifications, and Registrations
A number of organizations and colleges offer certification programs. The Skills Certification System, for example, is an industry-driven program that aims to align education pathways with career pathways. In addition, journey-level certification is available from state apprenticeship boards after the completion of an apprenticeship.
Completing a certification program provides machinists and tool and die makers with better job opportunities and helps employers judge the abilities of new hires.
Important Qualities
Analytical skills. Machinists and tool and die makers must understand technical blueprints, models, and specifications so that they can craft precision tools and metal parts.
