CNC Machinist; M

Job Location

Washington, MO

The CNC Machinist is responsible for setting up, and operating computer numerical control (CNC) machines to produce high-precision components used in aircraft and related systems. The machinist works from technical drawings, blueprints, and CAD models, ensuring that parts meet strict standards for quality and precision. Unlike a machine operator, the CNC Machinist has advanced skills in machine setup and troubleshooting. They collaborate closely with engineering and quality teams to optimize production processes and maintain high accuracy.

• Program (if required), set up, and operate CNC machines to manufacture components in accordance with engineering drawings and specifications.
• Interpret complex blueprints, CAD models, and technical documents to determine machining operations, tooling requirements, and part dimensions.
• Select appropriate cutting tools, speeds, and feeds for machining operations, optimizing processes for efficiency and precision.
• Perform first article inspections (FAI) and in-process quality checks to ensure all parts meet customer requirements.
• Troubleshoot and resolve issues with machine tooling or setups to minimize downtime and ensure optimal production.
• Adjust machine settings and offsets as needed to maintain tight tolerances and quality control throughout the production run.
• Collaborate with engineering, production, and quality teams to improve machining processes and implement continuous improvement initiatives.
• Document machine setup procedures, part dimensions, and tool usage to ensure repeatability and consistency in production.
• Perform routine maintenance on CNC machines, ensuring they are in good working condition and calibrated according to specifications.

• Strong understanding of blueprint reading, geometric dimensioning and tolerancing (GD&T), and material properties used in the production of aircraft components.
• Knowledge of cutting tools, machining speeds, and feeds for different materials (e.g., aluminum, titanium, composites).
• Knowledge of quality control standards and inspection techniques, including the use of precision measuring instruments (calipers, micrometers, CMM).
• Familiarity with aerospace industry standards and safety protocols.
• Familiarity with CAD/CAM software (e.g., Mastercam, CATIA, Siemens NX) for developing and modifying CNC programs a plus.
• Proficiency in CNC programming (e.g., G-code, M-code) and operating various types of CNC machines, such as mills, lathes, and multi-axis machines a plus.

• Attention to Detail:
  Ability to ensure parts are machined to exact specifications, maintaining tight tolerances and preventing defects.
• Problem-Solving:
  Skilled at troubleshooting machine issues and adjusting settings to optimize performance and minimize errors.
• Technical Communication:
  Clear communication with engineers, quality inspectors, and team members to ensure alignment on part specifications and process improvements.
• Time Management:
  Ability to prioritize tasks and manage machine setups and production runs to meet deadlines and maintain productivity.
• Continuous Improvement: A proactive mindset in identifying opportunities to enhance machining processes and reduce waste.

• High school diploma or equivalent required.
• Minimum of 3-5 years of experience as a CNC Machinist, preferably in the production of high-precision components for aircraft or related systems required.
• Experience in CNC machine setup, operation, and programming (if required) for complex parts with tight tolerances required.
• Proficiency in operating 3-4-5-axis CNC machines aerospace machining experience is preferred.
• Familiarity with aerospace materials (e.g., titanium, aluminum, stainless steel) and their machining requirements preferred.
• Associate’s degree in Manufacturing Technology, Machining, or a related technical field is a plus.
