Machining tool operators interpret job orders / blueprints to determine machining operations, set up and operate machine tools to perform operations such as turning, milling, drilling, boring, planing, honing, broaching, and grinding, verify dimensions of machined parts using precision measuring instruments, enter codes to specify feed, speed, and cut of the tool path for computer numerically controlled (CNC) machine tools, and prepare an etching solution and immerse metal parts or work pieces in the solution to remove unwanted portions.
You must have some high school education. You may need college or other courses in machining. You usually receive several months' on-the-job training. With experience as a machine operator, you may move up the ranks to a senior position, such as a set-up operator. With apprenticeship training, you may move up the ranks from machining tool operator to become a machinist or tool and die maker. Many recent entrants have a high school diploma, and almost 2 in 5 have a trade / vocational certificate or community college diploma.
