Process evaluation based on inline measurement data describes the systematic derivation of quality and process-state information from continuously captured measurement values within a production line. The objective is not only the inspection of individual parts, but also the stable assessment and control of the entire manufacturing process.
Industrial Machine Vision: Measurement on Red-Hot Steel
Inline measurement systems generate continuous data streams. Only through structured feature extraction, trend analysis, and threshold evaluation can reliable conclusions about the current process state be derived. This extends traditional quality control toward continuous, data-driven process monitoring.
• Individual part evaluation: Pass/fail decision based on defined features.
• Process evaluation: Analysis of trends, drift, variation, and systematic deviations.
While individual part evaluation provides short-term decisions, process evaluation enables early identification of instabilities and helps reduce scrap and rework in the long term.
• Reproducible measurement data under serial production conditions
• Stably defined reference systems
• Consistent feature definitions over time
• Statistical evaluation and trend monitoring
• Integration into control and quality systems (e.g., PLC, MES)
Vibration, temperature changes, or cycle-time fluctuations must not lead to systematic measurement shifts. Only when the measurement system and evaluation algorithms are designed robustly can trends be interpreted reliably.
QuellTech develops inline 3D laser systems not only to capture geometries but also to generate reliable process information. Through structured feature extraction and systematic integration into production lines, measurement data becomes a valid basis for process evaluation and quality stabilization. This approach follows a clearly defined project process ranging from feasibility analysis to serial integration.
