Overview

Designed and built a 105-component Stirling heat engine, taking the project from CAD and drawing creation through machining, assembly, and testing.

My Role

  • Prepared engineering drawings and machining plans for shop approval.
  • Machined 15 components on CNC mills and lathes using Mastercam and conversational programming.
  • Used GD&T, DFMA, and tolerance stack-up analysis to improve part fit.
  • Designed and CNC-machined a jet-engine-inspired flywheel with a contoured surface polished to a mirror finish.
