Job Title: CNC Programmer Job Description 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. Essential Skills 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. Additional Skills & Qualifications Experience with CATIA V5 Manufacturing/Machining workbenches. Proficiency in toolpath simulation and verification software.
Knowledge of AS9100 quality documentation requirements. Why Work Here? Join a team that offers competitive salaries, excellent benefits, and skills training within a collaborative team culture. We value direct placement and invest in our employees’ professional growth. Work Environment Work on the 1st shift from 7am to 3:30pm, Monday through Friday. Flexibility to work 1-2 hours of overtime per day and some Saturdays as needed.
Our facility is a leading supplier of complex parts and assemblies for aerospace and defense customers, specializing in multi-spindle, long bed machining of hard metal and aluminum fracture-critical structural components.
