Sensors performance in laser-based manufacturing process quality assessment: a conceptual framework

摘要

Laser-based manufacturing processes are emerging in manufacturing. Thus, new requirements are created with respect to monitoring, control, and online quality assessment. This work describes a framework for both studying and designing the performance of an IR-vision sensor with respect to real-time on-axis laser-based process quality assessment. More specifically, utilizing physics model at machine level as well as experimental results, requirements are extracted for the efficiency metrics of the sensor. These requirements regard temporal and spatial characteristics of the sensor physical layer, as well as software (algorithmic) level specifications.
