CNC Machine Operator - Dayshift - Aerospace

CNC Machine Operators operate computer-controlled machines to perform one or more machine functions required to produce customer orders. Skilled Machine Operators are critical to our success, and the reliability and accuracy of our operators is essential. Operators work under varying degrees of supervision to perform simple and complex machining operations, and with development and demonstrated mastery of additional skills and training, operators can advance along our machining career track.

Essential Functions

• Performs daily point checks on assigned machines and reports concerns to supervisor; may initiate maintenance requests if appropriate
• Meets departmental/company goals and objectives promptly (i.e., efficiencies, scrap control, time motion, and setup time reductions)
• Accurately interprets product blueprints, drawings, sketches, setup sheets, and other work instructions
• Uses scales, calipers, micrometers, and height gauges to determine that the part is being machined to the proper specifications
• Removes and replaces dull cutting tools, following designated safety protocol and instructions
• Mounts, installs, aligns, and secures tools, attachments, fixtures, and workpieces on machines, using hand tools and precision measuring instruments
• Listens to machines during operation to detect irregular sounds (i.e., dull cutting tools or excessive vibration); adjusts machines to compensate for problems and notifies lead or supervisory personnel as appropriate
• Adjusts machine feed and speed, changes cutting tools, or adjusts machine controls when automatic programming is faulty or if machines malfunction
• Stops machines to remove finished workpieces or to change tooling, setup, or workpiece placement according to required machining sequences
• Lifts workpieces to machines manually or with hoists or cranes
• Enters control instructions into machine control units to start operation
• Monitors and adjusts/controls coolant systems as needed
• Transfers commands from servers to computer numerical control (CNC) modules, using computer network links

• A minimum of three (3) years experience in a manufacturing role utilizing complex multi-axis machining centers is required; relevant apprenticeship or vocational training in a machine shop, manufacturing technology, or similar program may be considered in combination with paid work experience

• Experience reading & accurately interpreting shop blueprints, sketches, and other technical information/instructions is required
• Demonstrated basic math skills (add, subtract, multiply, divide, fraction conversions)
• Experience using mics, calipers, height gauges, and other precision measuring equipment is required
• Experience using indicators to verify flatness and straightness of tooling and fixturing
• Experience troubleshooting production issues and program edits
• A history of consistent employment without unexplained or significant gaps or frequent job changes is expected
• Completion of assigned internal training for Level III Operators, and periodic retraining or recertification is required
• Experience using cranes, forklifts, and similar heavy & oversized material handling equipment is preferred
