Senior CNC Programmer

JOB SUMMARY:

The Senior CNC Programmer is responsible for developing, optimizing, and implementing computer-aided design (CAD) and computer-aided manufacturing (CAM) programs to be used in the machining of Die Casting components. The role requires expertise in CNC programming, a strong understanding of aerospace /Defense engineering specifications, and a focus on precision, efficiency, and safety in manufacturing processes.

ESSENTIAL DUTIES AND RESPONSIBILITIES:

• Create and modify CNC machine programs using CAD/CAM software (e.g., Mastercam, Siemens NX, CATIA, SolidWorks).
• Develop machining strategies for complex aerospace Diecast parts, ensuring they meet engineering specifications and tolerance requirements.
• Generate tool paths and setup instructions for CNC mills, lathes, and other advanced machine tools.
• Review 3D CAD models and technical drawings of Diecast components to identify key machining features and requirements.
• Collaborate with engineers and designers to resolve design and manufacturing challenges.
• Ensure proper tool selection and optimize machining parameters (cutting speeds, feeds, etc.) for efficiency and part quality.
• Set up CNC machines with appropriate fixtures, tools, and materials to produce parts per design specifications.
• Collaborate with quality assurance teams to ensure that parts meet strict aerospace standards, including material properties and dimensional accuracy.

• Perform test runs and make necessary adjustments to CNC programs to achieve optimal results.

• Verify that finished parts meet required tolerances through measurement and inspection.

• Maintain and update CNC program documentation, including revisions, process sheets, and work instructions.
• Provide feedback and reports on production performance, efficiency, and any areas for improvement.
• Analyze manufacturing processes and suggest improvements in tooling, machining methods, and workflow to reduce cycle times and costs.
• Work closely with engineers, machinists, and production teams to ensure that CNC programs are executed correctly and meet all operational and customer requirements.
• Communicate clearly regarding changes or adjustments to programming and tooling.
• Perform basic part measurements during setup to validate linear dimensions
• Calibrate and modify machine fixtures during process development as needed.

Qualifications

EDUCATION AND/OR EXPERIENCE REQUIRED:

• Highschool Diploma 8+ years' experience in CNC programming, manufacturing engineering, preferably within the aerospace Die Casting industries.
• Hands-on experience with CAD/CAM software (e.g., Mastercam, Siemens NX, CATIA).
• Advanced to Expert level skills in interpreting raw CMM results to develop precise CNC programs, including the application of probing techniques for in-process inspection during machining.
• Extensive experience with CNC milling, turning, and multi-axis machines.
• Familiarity with aerospace materials, tolerances, and inspection methods is highly preferred.
• Proficient in the use of CNC programming languages (e.g., G-code, M-code).
• Strong knowledge of machining techniques, tooling, and fixtures.
• Ability to read and interpret complex technical drawings and blueprints.
• Familiarity with aerospace industry standards (e.g., AS9100, FAA regulations).
• Excellent problem-solving and troubleshooting skills.
• Strong communication and interpersonal skills for collaboration across teams.

OTHER SUBJECTIVE CRITERIA:

• Certification in CNC programming or machining (e.g., from NIMS, FANUC, or similar organizations).
• Capable of programming 5 axis simultaneous and active probing on Doosan, Brother, and Haas.

PHYSICAL REQUIREMENTS:

• Must be able to lift up to 25 lbs.
• Must be able to work standing up for long hours.
