Predicting Industrial Heartbeats: Building a RAG Pipeline for Mechanical RUL with Elastic In the world of Mechanical Engineering , an unplanned machine failure is more than just a repair bill—it’s a disruption to the entire production lifecycle. As a final-year student at Pragati Engineering College, I’ve spent months exploring how to turn raw sensor data into actionable intelligence. The Challenge: From Reactive to Proactive Traditional maintenance relies on simple thresholds (e.g., "if temperature > 90°C, stop"). However, machinery degradation is often subtle and nonlinear. My project, the Autonomous Mechanical Health & RUL Monitor , seeks to solve this by identifying early degradation patterns using AI. Why "Vectorized Thinking" with Elastic? To move beyond simple alerts, we need to treat machine states as high-dimensional data. This is where Elasticsearch shines as a vector dat
