Overview

Nowadays manufacturing processes go beyond simple stamping, molding or CNC machining steps. They include advanced processes that notably imprint specific texture on surfaces in order to improve parts function, like lower friction, extend lifetime or improve aesthetics in the often referred to finishing step.

This webinar illustrates how advanced optical profilers accurately assess complex surface texture through areal roughness parameters from ISO25178 norms. We discuss how these same profilers can be used to optimize manufacturing processes and then control the quality of the finishing step. Practical industrial cases will be shown- from a standard mechanical part used in orthopedics to a polymer 3D printed surface made using additive manufacturing.

Raphaël Deltombe
Raphaël Deltombe
Morphomeca (LAMIH, Valenciennes, France)
Raphaël Deltombe has a PhD in mechanical science and hold CNRS's research engineer position at Morphomeca team lead by Prof. Maxence Bigerelle. His main research activities are centered on exploration and analysis of microscopic texture applied to industrial manufacturing pieces in order to identify specific roughness signature as a function of environment parameters (Process parameters, lifetime...).
