A computer numerical control (CNC) operator produces machined parts by programming, setting up, and operating the CNC machine according to defined specifications of customers. 
Brian Robertson is a CNC Machine Operator for Ellwood City Forge, a maker of open-die forgings for a range of industries including oil and gas, power generation, shipbuilding and aerospace. He began in inventory control management and worked his way up to his current position. “I've always been good at figuring things out in my head and with DIY projects.  Now, after gaining experience here, I consider myself a surrogate sculptor. The customer provides a basic blueprint and a vision and we program and operate the machine to produce that.  It feels good to be part of something much larger.” In Brian's case, that something larger is often the crankshaft of a cruise ship or seal-off valves for an oil rig.
