Autonomous MES & IoT Telemetry Architecture for Precision Manufacturing
Engineered a low-latency edge-to-cloud Manufacturing Execution System (MES) with real-time OEE telemetry, machine data ingestion, and automated quality defect tracking.
Executive Summary & Mandate
Organization Profile: Tier-1 Precision Die-Casting & CNC Machining Manufacturer (4 Plants, 1,200+ Operators)
Core Engineering Mandate: Fragmented paper logs and air-gapped SCADA stations caused 18% unplanned downtime and delayed shift audits.
The Legacy Bottlenecks (Before)
- Manual clipboard logging by machine operators delayed defect identification by up to 6 hours.
- Air-gapped PLC controllers prevented cross-plant production visibility for plant executives.
- Scrap rates exceeded 7.2% due to delayed tool-wear detection on 5-axis CNC cutters.
- Shift handover meetings consumed 45 minutes reconciling conflicting paper records.
Engineering Approach & Implementation (During)
Edge Gateway Protocol Translation
Deployed hardened industrial edge gateways collecting high-frequency vibration, temperature, and cycle-time signals, converting raw registers into structured telemetry.
Time-Series Telemetry Ingestion Pipeline
Architected a PostgreSQL and Redis time-series ingestion worker pool processing 25,000 telemetry points per second with automated partition rolling and compression.
Live Shop-Floor Operator Touch Dashboard
Built responsive touch-screen shop-floor interfaces in Next.js providing operators with real-time cycle status, spindle thermal alerts, and digital work order queues.
Architectural Safeguards & Protocols
- Sub-200ms edge telemetry processing with local disk buffering during WAN interruptions
- Role-based access control (RBAC) isolating floor operator views from ERP financial schemas
- Automated statistical process control (SPC) rules alerting on tool wear drift
Quantified Operational Impact (After)
- Achieved real-time OEE calculation across 84 CNC machining centres and casting cells.
- Reduced material scrap rate from 7.2% to 2.1% through proactive tool replacement notifications.
- Saved 3,200 annual managerial hours previously spent compiling manual shift reports.
