In the fall semester of 2020, I was able to obtain a mechanical engineering co-op experience. I worked for an aerospace electronics company in Ohio and contributed to the creation of engineering drawings and mechanical analysis during my work term.
During this experience I was hoping to get a better understanding of what a day in the life of a mechanical engineer looks like along with what I liked and disliked about the job. When it comes to aerospace applications, I quickly realized that details are extremely important. The electronic box units that this company manufactures and designs have flown on satellites, rockets, and Mars rovers. The failure of these units could cause loss of hundreds of thousands of dollars or even human lives. I gained a much greater appreciation for the need to be very intentional with every design decision.
As far as engineering in general, I also learned how much time is spent in the documentation phase. Documentation is one of the most important steps of the design process. This process establishes an ability for other engineers to follow your work and ensure that all requirements are validated. As a result, often more time is spent in this phase than the analysis phase, which is what you are typically focused on learning in college. When it comes to my preferences, I learned that I enjoyed a lot of the software-related tasks more than the structural design components of a project.
One large task I was responsible for throughout the semester was implementing engineering change notices. Every part or component that the engineers design must be released with an official mechanical drawing, and this drawing contains all relevant information about the part. It includes the material the part is constructed from, its relevant dimensions, and sometimes which other parts it is assembled with. When any type of drawing change is deemed necessary, a change notice must be created and released to the document library. This change notice details exactly what changes were made to the drawings, why they were made, who authored the changes, and when they were authored. This could be a tedious process, as the entire procedure and documentation must be generated for even the smallest of changes. I got the chance to work on creating and implementing change notices for chassis, manufacturing fixtures, wire assemblies, and more.
My biggest technical design tasks included creating a screw capture plate for manufacturing and a “connector key” for a test harness. The screw capture plate was designed to hold all the screws, nuts, and washers needed for the assembly of a chassis. The purpose of the plate was to ensure that the manufacturing technician had visually accounted for and installed every necessary fastener in each unit. The “connector key” was attached to a harness plug and protruded laterally, which provided a physical barrier to impede plugging into one of the two jacks. The purpose of this key was to prevent the test technician from plugging wires into an incorrect jack, which would permanently damage the test unit. These tasks challenged my engineering design skills, and they also helped me to realize what part of the process I enjoyed the most.
As a co-op I also got to take part in a unique experience, as my site was hosting the company’s inaugural women in technology conference. The event had to be virtual this year, but I got the chance to act as a zoom host, and I was also in charge of collecting the speakers’ biographies, abstracts, and slide decks. There were seventy speakers, including many senior directors and technical fellows. Through this opportunity I had the chance to network and speak with many engineers from across the country. Their conference talks and sessions ranged from very technical topics, to career journey presentations, to professional development advice. I was able to network with many experienced engineers through my role as a host, and I learned a lot about being an engineer. I realized that there is not a single path to becoming successful, and that it is important to follow your passion.
The personal transformation I experienced as a result of my co-op experience, made possible through STEP funding, will have a lasting impact on both my personal life and professional career. I made connections through my daily work and the technical conference that I plan to keep up with throughout my career. As my time in college draws closer to its end, I begin to focus more and more on where I see myself after graduation. After this experience I feel assured that I will enjoy being an engineer and taking on innovation as the focus of my career. I also realized that I may hope to be more focused on some non-traditional areas for mechanical engineers such as controls and software. In order to enter these specialty fields, I may need to consider graduate school.
This project was important to me because I want to have a good idea of where I see my career going prior to graduating. Although classwork is important and provides the foundation for your knowledge as an engineer, it is impossible to know exactly what you want to do in the long-term without getting some hands-on experience first. The day-to-day work may look very different than you had imagined, and it is extremely helpful that you know this before committing to a fulltime job. Overall, I am grateful that this experience has given me a clearer idea of my passion, connections that will hopefully last a lifetime, and real-life engineering experience that has strengthened my confidence in my technical skills.
