Improving Cycle Time Accuracy with Computer Vision for Rotor Blades

Cycle Time’s Outdated Tracking Process in Wind Turbine Blade Manufacturing

In wind blade manufacturing, where every hour on the production floor carries significant labor and equipment costs, precision matters. But too often, one of the most important metrics – cycle time – is still tracked manually with outdated systems that miss the nuance of what’s happening at the mold.

With growing pressure to increase throughput and reduce cost per blade, manufacturers need high-fidelity, real-time insights into how long each blade spends at every stage of production. This is where computer vision is changing the game.

Why Accurate Cycle Time Tracking Matters

Wind blade manufacturing is a complex, multi-stage process involving mold layup, resin infusion, curing, bonding, trimming, and inspection. Small inefficiencies add up quickly – a few hours of delay per blade can equate to weeks of lost production annually.

Precise cycle time data matters because it enables:

• Bottleneck Identification: Knowing exactly how long blades sit in molds, on cure stations, or between stages highlights where throughput is constrained.
• Process Optimization: Engineers can correlate cycle time fluctuations with resin cure performance, staffing levels, or equipment downtime.
• Accurate Scheduling & Capacity Planning: Precise cycle time data improves forecasting and helps match available capacity to demand.
• Proactive Identification of Issues: Deviations in standard cycle times can trigger alerts that drive immediate action.
• Benchmarking & Lean Improvements: Teams can measure the impact of process changes, new materials, or automation initiatives with hard data.

The ROI of accurate cycle tracking is real – reducing cycle time by just 10% across a plant running 500 blades/year could recover thousands of labor hours, reduce tooling bottlenecks, and deliver millions in annual productivity gains.

The Problem with Manual Tracking

Despite this, many manufacturers still rely on:

• Manual logging by operators in scattered legacy systems
• Barcode scans at the start and end of stages
• Estimates based on schedule rather than actual movement

These methods are prone to errors, inconsistent usage, or are simply skipped in the rush of production. They also place a burden on already-busy line workers and don’t provide real-time visibility.

How Computer Vision Automates It All

By installing overhead cameras above each mold, products like WorkWatch enable non-intrusive, continuous monitoring of blade progress. Using AI, manufacturers can now detect when each stage starts and stops. These transitions are timestamped automatically, without any manual input from workers.

How it works:

• Cameras are positioned to capture the entire mold area.
• Vision models continuously analyze the scene in real time, detecting each stage transition.
• Data is streamed in real time, providing supervisors, planners, and engineers with instant visibility into blade status and mold utilization.

Benefits Beyond Automation

WorkWatch not only reduces the need for manual data entry – it also:

• Increases Data Reliability: Every blade’s cycle is consistently recorded with images, creating a trusted data trail.
• Enables Proactive Intervention: If a mold sits idle longer than usual, the system can alert managers before delays compound.
• Supports Traceability and Quality Tracking: When paired with defect detection, teams can correlate quality issues with exact process durations and timings.
• Feeds into MES and Dashboards: WorkWatch integrates with factory software to populate dashboards and support analytics, without requiring new workflows for the shop floor team.

Faster Blades, Profitable Factories

Accurate cycle time tracking isn’t just a KPI—it’s the foundation for lean, scalable, and profitable blade manufacturing. With computer vision, what was once a manual, error-prone task becomes a fully automated insight engine.

By combining cameras and the WorkWatch platform, blade manufacturers can unlock real-time visibility into the most critical stage of production—without burdening their workforce or compromising accuracy.
