On February 16, 2026, R-Ladies Rome hosted From Data to Decisions: Digital Twins for Smarter Maintenance, a practical session focused on how data science moves beyond notebooks and into real production systems.

The talk presented a physics-informed approach to Condition-Based Maintenance (CBM) through a real-world aerospace case study. The central question of the session was clear:

How do we detect failure before it happens — and make decisions that reduce cost and risk?

🧩 Tutorial Overview

The session was delivered by Priyanka Schnell, Chief Technology Officer at Insurfox. With experience in enterprise-scale digital systems and aerospace manufacturing, Priyanka guided us through how sensor data, physics models, and anomaly detection can work together in production.

The context: robotic drilling in A321 wing assembly. A single snapped drill bit can cause burrs or delamination, potentially scrapping a wing skin valued at €150,000. Traditional maintenance policies replaced drill bits after a fixed number of holes — a strategy that often led to premature replacements or unexpected failures.

Instead of relying on static thresholds, the session introduced a digital twin approach.

We explored:

  • how high-frequency sensor data (torque, vibration, speed, feed rate) can be transformed into meaningful features
  • why Specific Cutting Energy helps detect “wasted energy” before functional failure
  • how regime normalization allows comparison across aluminum and titanium cutting
  • how Isolation Forest can identify deviations without labeled failure data
  • why persistence rules (e.g., “6 of 12”) reduce alert noise
  • how early detection within the P–F interval provides actionable lead time

The session included a live walkthrough in Google Colab using simulated data to demonstrate the workflow step-by-step.

🔊 About the Tutorial

This session is part of the R-Ladies Rome Tutorials series, which focuses on practical workflows and real-world data applications.

Our goal is to show how data science connects to operational systems — where decisions have financial and technical consequences. We aim to make advanced topics accessible without removing the rigor behind them.
