New Measurement Method and Uncertainty Estimation for Plate Dimensions and Surface Quality

Abstract EN

Dimensional and surface quality for plate production control is facing difficult engineering challenges.

One of these challenges is that plates in large-scale mass production contain geometric uneven surfaces.

There is a traditional measurement method used to assess the tile plate dimensions and surface quality based on standard specifications: ISO-10545-2: 1995, EOS-3168-2: 2007, and TIS 2398-2: 2008.

A proposed measurement method of the dimensions and surface quality for ceramic oblong large-scale tile plate has been developed compared to the traditional method.

The strategy of new method is based on CMM straightness measurement strategy instead of the centre point in the traditional method.

Expanded uncertainties budgets in the measurements of each method have been estimated in detail.

The capability of accurate estimations of real actual results for centre of curvature (CC), centre of edge (CE), warpage (W), and edge crack defects parameters has been achieved according to standards.

Moreover, the obtained results not only showed better accurate new method but also improved the quality of plate products significantly.
