Several methods of measuring aluminum plates

  The thickness is measured with a micrometer of 0.01 mm.

  Length and width and diagonal measurement with a precision of 1 mm

  The unevenness places the plate freely on the platform. After the smoothness, the maximum gap between the plate and the platform is measured, that is, the unevenness.

  The unevenness of the sheet: longitudinal unevenness (d / length is not flat). There are three types of lateral irregularities (d/W width unevenness) and local unevenness (d/R local).
