Manufacturing AI in 2026 · what actually works on the shop floor

Most manufacturing AI pilots die at the gap between the demo and the line. The PLC is 20 years old, the network drops Wi-Fi at the press shop, and the operator wears gloves. AI that ignores any of those three doesn't ship. Here's what does.

Bet 1 · Vision QC on the line

A camera, an edge box (Jetson / industrial PC), and a defect classifier. Reads better than human at consistent flaws (scratch, mis-fill, misaligned label). Pays back in 6-9 months on any line where defects are >0.5% of throughput. Don't over-engineer · the model lives on the edge, syncs labels nightly, and falls back to 'pass everything' if the camera dies.

Bet 2 · Predictive maintenance from PLC + vibration data

Pull current draw, cycle time, vibration spectrum off the existing PLC + bolt-on accelerometer. Train per-asset. Forecasts bearing failure, motor degradation, gearbox wear 2-6 weeks ahead. Pays back the moment one unplanned stoppage costs more than the model spend (usually inside the first quarter).

Bet 3 · Operator copilots on plant SOPs

RAG on the plant SOPs + maintenance manuals + lessons-learned. Operator asks 'how do I clear this fault on line 3?', gets the right page in <2 seconds. Replaces 'who knows the trick for this machine' tribal knowledge with retrievable answers. Eval-gated so the answer always cites the source page · no hallucinated procedure is going to a press.

What to skip in 2026

• Digital-twin everything · the data fidelity isn't there for most plants and the maintenance burden is huge
• Fully-autonomous lines · you'll trade a known headcount cost for an unknown failure-mode cost
• Generative AI for CAD · the QA loop is where engineers earn their salary
• Generative process design · LLMs don't know what your plant can actually run

How we engage

Two-week shop-floor audit · we walk the line, talk to operators, look at one week of PLC logs. End of week two: a ranked list of 3-5 bets with payback estimate. Then a 6-12 week build for the top one. EU-compliant, NIS2-aligned, IEC 62443 posture · the manufacturing audit pack is part of the deliverable, not an upsell.
