A professional who sets up and operates multiaxis, numerically controlled routing machine to cut and shape metallic and nonmetallic workpieces. Respnsibilities include:

• Selects and positions workpiece on machine bed.
• Threads perforated or magnetic tape through read head.
• Inserts precision indicator in machine chuck, and depresses switches to jog chuck into contact with workpiece, synchronize tape and tool, and record setup point.
• Retracts chuck, and loads and secures first preset cutting tool and holder.
• Starts machine and observes operation.
• Compares numerical data displays with specifications on operation sheets, and uses scales, gauges, and micrometer to verify machining operations.
• Removes and replaces cutting tool when worn or damaged or when new cutting tool is specified by operation sheets.
• Assembles and presets cutting tools at bench during tape-controlled machining to reduce machine downtime.
• Repositions workpiece for intermediate setups when specified on operation sheets, and removes and replaces workpiece at end of machining cycle.
• Verifies new tapes by starting machine and observing operation to detect errors, plotting two-dimensional movement with recording stylus, or by machining sample workpiece and inspecting each cut, using precision gauges.
