Computer Numerically Controlled Tool Programmers

Computer numerically controlled (CNC) tool programmers create the digital instructions that tell automated manufacturing equipment exactly how to cut, drill, or shape metal and plastic parts. They work primarily at computer workstations, writing and testing code that guides machines through precise sequences of operations. Their day involves analyzing engineering blueprints and technical drawings, then translating those specifications into programming language the machines can execute. They calculate speeds, tool paths, and cutting depths while accounting for material properties and tolerances measured in thousandths of an inch.
