TUTORIALs  Monday 26'th of June

Multi-scale geometric analyses and principles for surface metrology

Professor Christopher Brown at Worchester Polytechnic Institute, Worcester, USA likes that work on surface metrology combines the beauty of fractals with the challenges of characterizing chaos using experimental mathematics. He likes surface metrology because surfaces cover everything – working with anthropologists studying marks on teeth, archaeologists to study wear on stone tools, and art conservationists to understand the surfaces of photographic paper and other artistic works.  He has published over a hundred articles on design, surfaces and surface metrology and has patents on a fractal method for characterizing surface textures and for friction testing.

Surface texture analysis

Dr. Francois Blateyron Director one of the founders of Digital Surf will give inroduction and examples of possibilities in analysis and characterization of surface texture measurements from a broad range of applications.  The tutorial will be given on the software MountainsMap and besides basic techniques also stereographic measurements, image analysis as well as characterisation using the latest ISO 25178 series will be demonstarted.

Additive manufacturing and texture characterization

Professor Liam Blunt has worked since 1990 in the areas of Surface Metrology and Precision Engineering. His current role is in the Centre for Precision Technologies (CPT) at the University of Huddersfield and he is the current Director of research for the CPT and coordinator of external industrial activities within the centre.
Within the Centre for Precision Technologies his specific areas of research include surface metrology, the development of standards for 3D surface measurement, manufacturing processes and precision environment design and metrology in Roll2Roll manufacture.

Multi Scale Characterisation and Manufacturing

Professor Mohamed El Mansori from the Department of Mechanical, Material Science and Manufacturing Engineering at the Arts et Métiers ParisTech
(www.msmp.eu).  His research activities have engulfed to the problems concerning the tribological characteristics of engineering systems and multiscale advanced manufacturing processes. These activities have led to the creation of a team who conceived and developed the concept of multiscale process signature in conjunction with a new tribo-energetic approach for the fundamental understanding of advanced and sustainable manufacturing processes. The interests of this approach are in its capability to "bridge the gap" between the traditional approach of academia and the industrial requirements.  Mohamed has published  more than 100 papers in international journals and more than 150 publications in international and national conference proceedings.

Advanced Surface Characterization

Professor Hassan Zahouani at University of Lyon and ENISE S:t Etienne. Author of more than 150 international Publication and conferences.  Hassan is a specialist on surface engineering and Tribology and his research has been concentrated to Surface science and Tribology of solids, Abrasion of materials, Mathematical morphology and 3-D imaging of surface Topography, Tribology of Skin, Mechanical and sensorial Properties of Skin.  He is also President of the French Cutaneous Engineering Society as well as Member of The European Institute of Tribology and Member of the International Society of Skin Imaging.

Principles of 3D interference microscopy for
surface metrology

Dr. Peter de Groot is the Executive Director of R&D for Zygo Corporation. A Physics PhD specializing in applied optics, Peter has published 140 technical papers, tutorials and book chapters in the fields of atomic physics, holography, optical testing, surface structure analysis, semiconductor wafer process metrology, stage motion measurement, international standards for metrology, and large-scale coordinate measurement. His research has led to 130 US patents and several commercial products. He is an SPIE Fellow, a Fellow of the Optical Society of America, and a multiple award winner for innovation. Peter enjoys teaching university courses as well as professional short course in optical metrology.

Interference microscopy plays an important role in non-contact strategies for 3D measurement of surface characteristics that influence the functional behavior of manufactured parts. This tutorial reviews the history and principles of important technique, then concentrates on the hardware, software and applications of interference microscopy using phase shifting and coherence scanning measurement principles. Recent advances considered here include performance enhancements, new objective designs for wide-field imaging, vibration robustness, accommodation of highly sloped surfaces, correlation to contact methods, metrology for additive manufacturing, and transparent surface films analysis.
