INVESTIGATION OF POINTS SAMPLING STRATEGIES IN CASE OF FLATNESS
Keywords:Geometric tolerances, Flatness, Point sampling strategy, Coordinate measuring, Minimum zone method,
AbstractThe use of geometric tolerances has increasing importance in the industry, but the correct application of it needs deeper understanding. Several aspects should be considered like the work of the product, material properties, manufacturing and measuring circumstances, and the regulations of concerning standards. The article presents the measuring and evaluation problems through the example of flatness. The effect of different point sampling strategies is investigated: twelve methods are compared in case of eight test surfaces, and a modification method is suggested.
