“…In additions the ability of the new method is more accurate than that of the traditional one due to the reach of the highest point on the lengths of diagonal, edge, and warpage after the use of more precise measurements. Moreover, it can clear that the CMM machine has highly proved in the measurement of oblong large-scale ceramic tiles than the vision inspection methods [7][8][9][10].…”

“…It is a custom measurement tool using a point laser for almost plane surfaces of objects [4]. Therefore, there is limited number of studies in this area, while some new publications are carried out using image processing, vision inspection system, morphological techniques, and texture analysis [5][6][7][8][9][10]. Quality inspection of ceramic tile using statistical techniques and neural networks approach is also studied [11].…”

“…The capability of dimensions and surface quality measurement of tiles has been discussed in detail as well. Thus, the new measurement method could be able to assist the tiles of different scales not only to produce better accurate method compared to other methods Step width = 3 mm Fitting technique LSQ [7][8][9][10] but also to permit improved manufacturing quality of ceramic tile products.…”

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.
