A fitter machinist is a person who makes machine parts and, in some cases, constructs the machine itself. Because metal fabrication is such an important part of the fitter machinist job, applicants must have basic to moderate math and science skills, as well as basic communication skills. In addition, the machinist must be able to read blueprints and other plans accurately. A high school diploma is usually required, and post-secondary education in the form of a professional certificate or a degree may be required as well.
A degree is not always required; instead, a person who wants to work as a fitter machinist can apply for an apprenticeship with a local union or a private company. This apprenticeship can last anywhere from one to five years, during which time the new fitter machinist will learn all of the skills necessary to do the job correctly. He or she will work under the direction and supervision of a more experienced machinist, and the apprentice will earn all relevant certifications or clearances during the apprenticeship period. Computer numeric control (CNC) programs are frequently used in machining, so the apprentice will need to learn how to use CNC programs as well as computer aided drafting, or CAD, programs in some industries.
Because the parts being manufactured must be built to very tight specifications, math skills are required to become a fitter machinist. Math skills will aid the fitter machinist in performing calculations and making necessary changes to computer programs. Following the creation of the parts, the machinist may need to assemble the machine to ensure that it functions properly. If certain parts fail to function properly, the fitter machinist will likely collaborate with an equipment designer on this step, as the machinist may not have been directly responsible for the machine’s design in the first place.
It will be necessary to assemble and maintain the machines that create the parts. Fitter machinists are usually in charge of this set-up and maintenance, and in many cases, fitter machinists are also in charge of performing in-depth repairs on the machines. At larger companies, specific maintenance personnel may be on hand to perform repairs and maintenance, but machinists are frequently trained or otherwise skilled in machine repair. Machinists will be in charge of troubleshooting and identifying potential issues with the machine.
