In practice, two surfaces statically equivalent can be issued from two different manufacturing processes (grinding, belt finishing, honing, …) or obtained using different working process variables (abrasives grits size, contact pressure, …). The common tools and different norms used for industrial surface characterization (ISO 4288, ISO 12085, …) have the main limit of discriminating them through their process signatures. This Note introduces a multiscale decomposition method of the surface topography based on continuous wavelets transform. This approach allows the determination of the multi-scale transfer function of the morphological modification on the surface topography after a finishing process. This technique has been successfully applied to discriminate two surfaces obtained by the belt-finishing process. Moreover, it makes it possible to connect the surface topography modification to the physical and tribological mechanisms of the process (ploughing, cutting, …).
Dans la pratique, deux surfaces statiquement équivalentes peuvent être usinées à partir de deux différents procédés de fabrication (rectification, toilage, rodage, …) ou obtenues à des conditions différentes du procédé (taille de grains abrasifs, la pression de contact, …). Les différents outils communs et les normes utilisées pour la caractérisation de surface industrielle (ISO 4288, ISO 12085, …) présentent la principale limite de les discriminer à travers la signature de leurs procédé. Cet article introduit une méthode de décomposition multiéchelle de la topographie de surface basé sur la transformée en ondelettes continue. Cette approche permet de déterminer une signature multiéchelle de la modification morphologique de la topographie de la surface après un processus de finition. Cette technique a été appliquée avec succès pour la discrimination de deux surfaces obtenues par toilage. Elle permet, en plus, de faire le lien entre la topographie de la surface obtenue aux mécanismes physiques et tribologiques du procédé (labourage, coupe, …).
