What does machinist mean?
A machinist is a skilled craftsperson or technician who operates machine tools and makes components to precise specifications. The work commonly involves turning, milling, drilling, grinding, or cutting materials such as metal, wood, and plastic. Machinists may work in machine shops, factories, engineering workshops, or specialized production environments, and they typically use drawings, blueprints, measuring instruments, and computer-controlled equipment. The word suggests technical precision as well as practical knowledge of materials and tooling. It differs from a mechanic, whose work usually focuses on diagnosing, maintaining, or repairing existing machinery or vehicles. Although “machine operator” can describe a similar occupation, “machinist” more often emphasizes advanced skill, craftsmanship, and the ability to produce accurate parts.
nounA person skilled in operating machine tools and making precision components from metal, wood, plastic, or other materials. The term may also refer generally to a worker skilled in the manufacture or repair of machinery.
