Resumen
Assessment of cylindricity has been traditionally performed on the basis of cylindrical crowns containing a set of points that are supposed to belong to a controlled cylinder – As such, all sampled points must lie within a crown. In contrast, the present paper analyzes the cylindricity for wear applications, in which a statistical trend is assessed, rather than to assure that all points fall within a given tolerance -- Principal Component Analysis is used to identify the central axis of the sampled cylinder, allowing to find the actual (expected value of the) radius and axis of the cylinder -- Application of k-cluster and transitive closure algorithms allow to identify particular areas of the cylinder which are specially deformed -- For both, the local areas and the global cylinder, a quantile analysis allows to numerically grade the degree of deformation of the cylinder -- The algorithms implemented are part of the CYLWEAR system and used to assess local and global wear cylinders
