Responsible for programming multi axis numerically controlled machine tools using NX and Catia V5 software to produce both composite and metallic aerospace parts. Created processes and NC programs for automated fiber placement of large, complex, core-sandwich skins using Catia composite workbench (CPD) and Ingersoll CPS fiber placement software. Created manufacturing data for hand layup processes such as ply flattening, ply nesting, and laser projection using CPD, Trunest, and Trulaser. Responsible for creating NC programs to trim and drill large aerospace assemblies consisting of multiple stacked materials including carbon fiber, aluminum, and titanium. Responsible for creating machining and workholding methods, designing tooling, creating tooling drawings and work instructions, and programming, verifying, posting, and optimizing NC code. Ensured toolpath accuracy and final part integrity by using CG Tech Vericut. Created NC programs using high speed techniques in soft metal (aluminum) and NC programs for complex monolithic hard metal structures (titanium). Maintained product configuration using Enovia. Provided collaborative design for manufacturing (DFM) assistance to engineering. Estimated programming hours and program cycle times. Assisted with new machine procurement, installation, and buy-off. Coordinated shop activities as needed.
