Something our eyes can not see:thermal imaging of wood machining process
Recent developments in the field of metrological sciences allow broader access to some measurement techniques up to now limited to few specialized applications. The thermal imaging is an example of such method. Reduction of the sensor cost and simplification of the calibration procedure opened new application areas of the thermal imaging. The paper shows an illustration of the thermal imaging potential into understanding, monitoring and optimization of the manufacturing process by the example of the classic wooden product Selected steps of the chair production have been photographed in both visible and infrared ranges. Thermal images provide very essential supplement to the visible-range pictures, extending the human perception into something we can not see. The level of temperatures is surprisingly high during some operations (such as sanding) and might reach more than 150℃. Some wood defects (such as cracks) can be detected with thermal imaging. Elevated temperature might be a first symptom of the machine breakage. The manufacturing process (guying or drying for instance) can be optimized by analyzing of the temperature distribution and its changes during time.
