The Problem

Three senior technicians—combined 120 years of experience—were approaching retirement. When a CNC machine threw an error code, they knew instantly whether it was a 5-minute fix or a shift-ending problem.

Newer techs would stop production, call a senior, wait for them to walk over, and lose 30+ minutes per incident. That tribal knowledge was irreplaceable—and walking out the door.

The Tribal Knowledge Problem:

  • Manuals existed, but didn't cover the "tricks" that actually solved problems
  • Average 45-minute delay per equipment issue while waiting for senior help
  • New hires took 18+ months to troubleshoot independently
  • Three retirements scheduled in the next 24 months

The business risk: $15,000/hour in production downtime, multiplied by every incident where knowledge wasn't immediately available.

The Fix

We spent two weeks on the floor with the senior techs. Every troubleshooting session, every "listen for that sound," every "check this first"—documented and structured. Combined with equipment manuals, maintenance logs, and incident histories, we built a system that thinks like a 40-year veteran.

Knowledge Captured:

  • Equipment manuals and spec sheets (12 machine types)
  • 5 years of maintenance logs and incident reports
  • Structured interviews with senior technicians
  • "Tribal knowledge" decision trees and shortcuts
  • Error code interpretations with real-world context

What We Built:

  • 1

    Troubleshooting Assistant

    Describe the symptom, get step-by-step diagnosis

  • 2

    Error Code Decoder

    Not just what the code means—what to actually do about it

  • 3

    Maintenance Oracle

    Predictive insights based on symptom patterns

The Stack

Vector DB:ChromaDB (on-premise)
LLM:Llama 3 (local deployment)
Framework:Custom RAG pipeline
Deployment:On-premise server (air-gapped option)
Frontend:Tablet interface (shop floor)
Input:Voice + text (noisy environment)

Manufacturing-Grade Deployment:

100% on-premise. No cloud dependencies. Works offline. Rugged tablet interface designed for shop floor use. Voice input for hands-busy situations.

"My guys were skeptical—'a computer can't know what I know.' Then they saw it suggest the exact fix they would have. Now they're adding their own tips to it daily."
