Surface Finish Optimization for Advanced Manufacturing by Optical Profiler

Understand positive impact of areal roughness parameters in driving finishing process in manufacturing.

Research Abstract

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.

Who Should Attend

  • Quality control engineers
  • Metrology engineers
  • Material Development researchers
  • Application engineers for Additive and 3D printing manufacturing
  • Designers of finishing means (blasting, tumbling, polishing, laser texturing)
