I'm currently in a CNC internship with a very small company trying to learn as much as I can before I graduate with a mechanical engineering degree. I couldn't land a traditional "engineering" internship this summer so called the closest CNC shop near me. It's a small company with only a three axis machine, saw blade, 3d printers, anodizing, etc with most orders generally less than 50 parts. Most of my job so far has been pressing a green button and deburring EVERYTHING. Right now I'm being given CAD parts to model and slowly learning more about the machine setup/tool changes.

How would I best utilize this knowledge to prepare me for engineering interviews? What can I push myself to learn more of to move towards a manufacturing career? I understand a CNC internship can give me a unique edge towards competitors, but I don't have many engineering peers right now to advise me about what specifically I should be learning about.
