We are seeking an experienced CNC Programmer skilled in CATIA V5 to develop CNC programs for large-scale aerostructure components machined on multi-axis gantry mills. The role involves translating CATIA V5 design models into machinable toolpaths for complex, close-tolerance structures utilized in aerospace and defense platforms. The ideal candidate possesses strong CATIA modeling and surfacing skills coupled with hands-on programming experience on large-envelope gantry machines.
Responsibilities- Develop, test, and optimize 3, 4, and 5-axis CNC programs using CATIA V5 for large gantry-style machining centers.
- Program complex aerostructure components, including monolithic wing skins, spars, ribs, and large sheet metal detail parts directly from CATIA design models and engineering drawings.
- Build and maintain manufacturing models, stock definitions, fixture assemblies, and tooling libraries within CATIA.
- Optimize toolpaths for material removal rates, cycle time, tool life, and surface finish while managing part deflection and thin-wall stability on large structures.
- Select appropriate cutting tools, feeds, speeds, and work-holding strategies for aluminum, titanium, and composite materials.
- Collaborate with manufacturing engineering, tooling, and quality teams to ensure programs meet GD&T requirements and first-article inspection standards.
- Perform program verification and simulation to eliminate collisions, gouges, and fixture interference prior to machine floor deployment.
- Support first-article setup and provide on-machine troubleshooting, including program edits and offset adjustments.
- Post-process CATIA toolpaths and troubleshoot post-processor output for specific gantry machine controllers.
- Maintain and update program documentation, setup sheets, and tool lists in accordance with AS9100 and customer quality requirements.
- Support continuous improvement initiatives to reduce cycle times and improve process capability on large-format work.
- Participate in DFM reviews for new aerostructure programs, providing manufacturing input on CATIA design models.
- 5+ years of CNC programming experience using CATIA V5, focused on large-part or aerostructure machining.
- Demonstrated experience programming multi-axis gantry or large-envelope machining centers.
- Strong proficiency with CATIA V5 surfacing and part design modules in addition to manufacturing modules.
- Strong understanding of aerospace materials and their machining characteristics.
- Proficiency in reading and interpreting complex engineering drawings, GD&T, and 3D models.
- Experience with toolpath simulation and verification software.
- Working knowledge of work-holding and fixturing strategies for large, flexible parts.
- Familiarity with post-processor logic and ability to troubleshoot post output.
- Strong understanding of AS9100 and aerospace quality documentation requirements.
- Ability to obtain and maintain any required government clearances and authorizations.
- Experience with CATIA V5 Manufacturing/Machining workbenches.
- Proficiency in toolpath simulation and verification software.
- Knowledge of AS9100 quality documentation requirements.
