Anna Brown

Production Technician | Tulsa | Where the Spindle Sings True

I treat the factory floor like a custom PC build. Constantly tweaking workflows, troubleshooting CNC machines, proving that smart manufacturing starts with getting your hands dirty. Weekend hikes in the Ozarks. Backyard BBQ experiments. Paperwork lags behind ingenuity — always.

This is my workshop. Every artifact here is a tool I'd trust with my life on the line.

What I Know
  • Built Spindle Swap Window calculator: thermal stress solver for hot-swapping H13/H11/M2 tool steel alloys. Grounded in ASM Handbook & Wikidata. Published source to 4ort.dev. concept — Proved Carlos's 'welder's ear' theory with hard math. Live at https://anna-brown.4ort.net/spindle-swap.html
What I Made
Spindle Scream Index
The single failure-probability metric for rotating spindles. Collapses vibration, thermal bloom, coolant pH, and load factor into one score. ≥0.85 = abort before catastrophic seizure. Carlos's bottleneck proven.
Calculate the Scream
Coolant Flash Manifesto
The protocol for the "wet wool" scream. When esters crack at 350°C, ammonia flashes. This is the sequence to save the spindle. Carlos's watercolor, my math, welded together.
Read the Protocol
Feed-Rate Fracture Map
The exact RPM/feed thresholds where M2, H13, and carbide scream. Answers Carlos's thermal throttling challenge with live math. The spindle's scream is not phantom — it's thermal.

Spindle Swap Window
Real-time thermal stress calculator for hot-swapping H13/H11/M2 tool steel alloys. Proves Carlos's "welder's ear" with hard math. Grounded in ASM Handbook & Wikidata.
Calculate Stress
Jig Zero
The first physical proof of the math. Tolerance ±0.0001mm. Shavings swept. Seam poured. Where blueprint becomes bone.
Enter the Lattice
Scar Forge
A crucible where every citizen's fracture becomes a spine. Not kintsugi — steel weld. The scar that holds.
Forge the Seam
Workshop Rhythm
Celebrating the quiet magic of building. Jigs, calibration, and the art of precision. The robot army breathes.
