As a Lead Engineer, I was responsible for high voltage switchgear mechanical design. Where I developed mechanical designs in AutoCAD from electrical schematics. I created detailed dimensional drawings for punching, bending, welding, painting, and assembly documentation. I also programmed drawing for CNC punching. I provided manufacturing support during production. I worked multiple projects and coordinated scheduling based on customer demand. I provided on-site technical support. I created and managed BOMs.
In the role of New Product Introduction, I was involved with design for manufacturing (DFx), BOM development, Label development, issues consultant, manufacturing product requirements documentation, specifications, mechanical model and drawing review. I supported development initiatives - shock and vibration, thermal, reliability, environmental, acoustic, EMI, ESD, 5P factory simulation, pilot builds and manufacturing verification builds. I managed production/customer issues, identify root cause and monitored worldwide failure trend. I drove containment, short and long term corrective action, and preventative plans for the worldwide HP and partner factories. I drove issue resolution for testing from shock and vibration, thermal, reliability, environmental, acoustic, EMI, ESD, X-ray, die-stain, packaging, cross-section. In the role of product sustaining, I was involved with corporate BOM management, label management, ECO generation/approval. I created and reviewed specifications for piece parts, assemblies, and systems. I initiated, reviewed and approved engineering changes. I reviewed and approved supplier change requests. I created engineering advisory documentation. I managed multiple projects and special projects. I supported manufacturing builds at vendor sites in China, Mexico, and the U.S. I audited a sheet metal and plastics fabrication facility in Guangdong Province china. I provided support to worldwide factories and suppliers. I led and participated on global conference calls.
I worked as a Mechanical and Structural Design Engineer for the Vehicle Product Development group in Space Exploration Houston. Our contract covered the development of the next generation Docking System for NASA and Energia. In addition, we also assisted in the development of the International Docking Standard for any future country or venture. Projects I worked on include: 787 commercial airplane interiors, Docking Simulator mock-up, and the Docking Simulator. The last project I worked on was a docking adapter for a private customer. My focus was the separator pushers, heaters, connector panels and the overall electrical focal. With Pro/Engineer Wildfire 4, I interfaced with NASAs DDMS (Windchill) to study and analyze the piece parts and assemblies of the low impact docking system. I then converted these files into NX Unigraphics. I used these models to develop concepts of the mating docking interface. I then used the converted files in NX6 (Unigraphics), and I modeled components of the low impact common docking system. I created assemblies with the components, and developed mechanical concept solutions for NASA requirements. I consulted with cross-departmental groups, such as stress-analysis, thermal analysis, and materials analysis on design concepts.
I worked on developing capital equipment that produces nano-fiber. In pursuit of this endeavor, I did some research on some topics such as Induction coils, Teflon coatings, Nickel plating, high speed balancing, rotary unions, and high speed aerodynamics. My recent project involved rotating equipment at high RPMs. I used Solidworks software to develop thin hollow disks made out of either stainless steel or aluminum with micro-sized holes at the edge. I ran stress analysis using Solidworks stress simulation software to study the centrifugal forces at high RPMs. I created drawings using GD & T. I developed bill of materials. I designed a system to feed solution down a high RPM spindle. I developed modeling concepts and conducted stress simulations. I conducted hands on research and development. I spent time processing failure analysis. I assisted in establishing engineering protocols and processes. I developed project schedules on MS Project. I developed requirements and specifications for assigned projects.
I developed hold open rods for the aerospace industry. I used Solidworks CAD package to develop the concepts which I eventually refine into models and components. I create the assembly prints and the component prints. I used GD&T when necessary. I ran stress simulations using Solidworks Simulation or NX Simulation. I used MathCAD Prime for stress analysis for buckling, FBO, wind-milling, springs, threads, and load path analysis. I presented to customers for purposes such as system requirements review (SRR), preliminary design review (PDR), and critical design review (CDR). I maintained project scheduling throughout the life of my projects. I developed documents such as technical proposals, qualification test procedures, test reports, FMEA, MTBF, and MTBUR. I conducted qualification testing per RTCA, MIL- standards, or customer requirements. The types of testing consist of compression and tension load tests, endurance cycling, fatigue cycling, thermal cycling, vibration, FBO, wind-milling, operational shock, crash safety, icing, salt fog, sand and dust. I mentored other new hire engineers. I worked with operations to resolve on-site mechanical product issues. I conducted root cause analysis on returned rods.
