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.

Machining tool operators work for machine shops and metal products and other manufacturing companies.
