How to: Surface roughness & finish

2D vs 3D profilometry 

Besides complying with geometric specifications in machining (shape and position tolerances) the surface finish of a workpiece plays the key role for functionality and quality. Surface roughness requirements can vary by several orders from <1 nanometer [nm] to several micrometers [µm].

What is roughness, how to define it? What is relevant in ISO 25178 and what does the new standard ISO 21920 mean? How to read and implement it in your daily quality control?

This free webinar dedicates to all engineers, technicians and designers interested in stepping up their game in profiling, quality engineering, surface inspections and roughness measurement. Our PolyXpert Joe will guide you, summerize common Q&A, give tips & tricks - for beginners over users to experts.

Attend this webinar and learn about...

  • ... the basic concept of measuring roughness in 2D + 3D
  • ... understand and apply measurement settings the right way
  • ... orientation in standardization and what changes with ISO 21920
  • ... where optical areal profiling speeds up while revealing more insights of your workpiece

Voices of Participants
 

Really good seminar [...], it clearly dealt with how to define and measure roughness.
 

I learned a lot. many thanks to the speaker.
 

The orientation about the new ISO standard helps, while we still measure 2D instead of 3D. thank you very much!
