Job Description:

• 1) Sets up and operates multiaxis, numerically controlled routing machine to cut and shape metallic and nonmetallic workpieces: Selects and positions workpiece on machine bed.

• 2) Threads perforated or magnetic tape through read head.

• 3) Inserts precision indicator in machine chuck, and depresses switches to jog chuck into contact with workpiece, synchronize tape and tool, and record setup point.

• 4) Retracts chuck, and loads and secures first preset cutting tool and holder.

• 5) Starts machine and observes operation.

• 6) Compares numerical data displays with specifications on operation sheets, and uses scales, gauges, and micrometer to verify machining operations.

• 7) Removes and replaces cutting tool when worn or damaged or when new cutting tool is specified by operation sheets.

• 8) Assembles and presets cutting tools at bench during tape-controlled machining to reduce machine downtime.

• 9) Repositions workpiece for intermediate setups when specified on operation sheets, and removes and replaces workpiece at end of machining cycle.

• 10) 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.
