Overview

As part of a CMU Manual Machining course, I manufactured a functional aluminum phone stand entirely by hand using traditional subtractive methods in the machine shop. The goal was to produce a part matching an engineering drawing within a ±5% tolerance while learning safe and precise operation of machine tools. This was done via edge-finding, threading holes, and using manual mills, lathes, and saws.

About the Project

About the Project

We were to manufacture a phone stand using a given engineering drawing, using manual machining methods. Dimensions had to be within 5% of the specified value.

  1. Starting from raw aluminum stock, I used a manual knee mill to cut and shape the base.

  2. The vertical pegs were turned from aluminum rod on a manual lathe, cut to length with a saw, and threaded for assembly.

  3. Holes in the base were edge-found, drilled, and tapped to accept the pegs.

  4. After verifying tolerances against the engineering drawing, I finished the surface with a sandblaster to create a uniform texture.

This project emphasized precision, accuracy, and manufacturability. It strengthened my ability to interpret engineering drawings and translate them into machined parts — a skill set that directly informs my approach to CAD modeling and prototyping.

This project reinforced the connection between design intent and manufacturability. By working within tight tolerances on manual equipment, I developed an intuition for what is feasible in fabrication — insight that I now bring to CAD design, rapid prototyping, and larger engineering projects.

Overview

Smart Fridge is a connected fridge system that helps people track aging produce, view their inventory remotely, and get recipe ideas based on what’s inside. Built in 8 weeks, the system uses image recognition and a custom touchscreen UI to reduce food waste and make cooking easier.

My teammate and I designed the physical housing, trained the produce classifier, and built a working prototype that combines a camera feed, screen interface, and functional enclosure.
