Marker-Free, Single Item Traceability in Gear Wheel Production Based on Inherent Surface Patterns: Close-to-Production Investigations on Two Different Types of Gear Wheels

Key Points

• Traceability of gear wheels improves with inherent surface patterns, enhancing manufacturing efficiency and reliability.
• Key evidence shows improved identification accuracy in 100% of tested gear wheels across two types.
• Observation of inherent surface pattern recognition methodology reveals potential for marker-free identification in production settings.
• This technique highlights the benefits of reducing material waste and production costs, while ensuring product integrity.
