Trainees start writing simple programs under the direction of an experienced programmer. Although machinery manufacturers are trying to standardize programming languages, there are numerous languages in use. Because of this, CNC programmers should be able to learn new programming languages. As new automation is introduced, machinists and CNC programmers normally receive additional training to update their skills. This training is usually provided by a representative of the equipment manufacturer or a local technical school.
Some employers offer tuition reimbursement for job-related courses.
Machinists and CNC programmers can advance in several ways. Experienced machinists may become CNC programmers, and some are promoted to supervisory or administrative positions in their firms. A few open their own shops. Despite slower than average employment growth, job opportunities will be excellent for machinists, as employers continue to report difficulties in finding workers with the necessary skills and knowledge to fill machining and CNC programming openings. Many job openings will arise each year from the need to replace experienced machinists and programmers who transfer to other occupations or retire.
