Northrop Grumman · Commerce, CA · Yesterday
On-siteInformation Technology$67k–$111k/yrFull-time
Core Responsibilities
- Utilize software such as Mastercam, CATIA, or Siemens NX to create toolpaths for 3-, 4-, and 5-axis milling and mill-turn machines.
- Design complete NC programs for complex 3, 4, and 5-axis mills, lathes, and mill-turns using CATIA V5/V6.
- CAD/CAM Integration: Analyze 3D CAD models and blueprints to determine the most efficient machining sequences and work-holding strategies.
- Tooling & Fixture Design: Design custom fixtures and jigs in CAD to secure aerospace components during the machining process.
- Simulation & Verification: Conducting machine simulations (e.g., using Veri cut or Completed) to ensure error-free toolpaths before physical production.
- Process Optimization: Continuously refine programs to reduce cycle times, improve tool life, and ensure consistent quality for high-value aerospace parts like landing gear or turbine blades.
- Researching tools and methods to reduce cycle times, improve part quality, and ensure cost-effective manufacturing.
- Create detailed setup sheets and tool lists to guide machinists through the production process.
- Troubleshooting programming issues during setup, performing "prove-outs" on the floor, and mentoring machine operators.
Basic Qualifications
- Education: High school diploma/GED and 4+ years of experience developing CNC programs for multi-axis machines in an aerospace environment.
- Software Proficiency: Deep knowledge of CAD software (e.g., AutoCAD, SolidWorks) and CAM software (e.g., Mastercam, Gibbs CAM).
- Blueprints & GD&T: Expert ability to interpret complex technical drawings and Geometric Dimensioning and Tolerancing (GD&T) symbols.
- Mathematical Aptitude: Strong foundation in Trigonometry and Geometry for calculating complex cutting paths and angles.
- Technical Knowledge: Deep understanding of G-code, M-code, and post-processing; expertise in machining aerospace alloys (Titanium, Inconel, Aluminum).
Preferred Qualifications
- Regulatory Compliance: Familiarity with AS9100 standards and export control regulations (ITAR/EAR).
- Associate's degree in a mechanical or machining related curriculum or 6 years of machining and programming experience.
