Abstract:
Methods and systems for determining the integrity of a manufactured board are disclosed. An example system includes a testing platform configured to secure the manufactured board, a sensor configured to measure a parameter corresponding to a flatness of a surface of the board, and a controller. The controller is configured to identify regions on the surface corresponding to one of a peak or a valley based on the parameter, and calculate a score representing the integrity of the manufactured board based on the identified peaks and valleys. The controller adjusts a flow rate, a pressure, a temperature, and position of a deposited substance in a manufacturing process based on a comparison with a height of the peak and/or a depth of the valley to stored peak heights and/or valley depths. In some examples, a mechanical tester determines a compressive strength and a density of the board at the identified regions.
