METROLOGY
During my time at Bose, I had the opportunity to learn how to program and run different measuring equipment to ensure sample parts were within specific tolerances. The machines I most frequently used were the Optical Comparator, a CMM Touch Probe sensor, and an OGP SmartScope. Using these machines, I toleranced thousands of magnets, spiders, speaker casings, cones, and other speaker parts, and offered input as to why parts are not meeting specifications. In metrology, repeatability of measurements across multiple samples is essential. In order to do this, I would make intricate test fixtures to hold parts delicately but securely. This would allow me to write programs to measure complex parts in the least amount of time.

GD&T
To be able to measure any part or tool that came in, learning GD&T was essential. During my first few weeks, I took a course on how to read and create drawings in a way that can universally be understood. Fluency in GD&T helped me effectively measure any parts that came in, as well as allowed me to be flexible with my measuring processes. I was frequently working with other engineers around the facility, measuring anything they needed in a timely manner. By the time I left Bose, I could quickly look at a drawing and know within seconds the process I would need to follow in order to accurately measure any feature on the part.
SOLIDWORKS MODELING
During my downtime in between tests, I would take random parts from around the office and model them on SolidWorks. Many obscure and interesting parts from advanced development would come in, so using calipers and the measuring tools provided to me, I remolded parts these parts on SolidWorks. Due to company restrictions, I was not able to take any of the SolidWorks files I created during my time at Bose. So, in order to display the kinds of things I was modeling, I designed a few parts with similar features. A further description of each part can be found on my personal projects page.
