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.

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.
