Latest Notepad Video: Material Ratio Curve

The sixth video in the Notepad Series from Digital Metrology Solutions has been released.

‘The Material Ratio Curve’ video looks at this rather well-known curve (historically known as the Abbott-Firestone Curve). It shows the amount of material that encountered as we move further down into a surface. That can tell a lot about the surface: how durable it may be, how it could carry lubrication and how well it may wear.

“In this introduction we show how the material ratio curve is derived. Then, we show you some examples that will help you estimate the nature of a surface from the shape of its material ratio curve” said Mark Malburg, President of Digital Metrology.

“This video series is designed to introduce casual users to surface analysis. Many technicians, researchers and engineers rely on surface data but only have a passing knowledge of how to explore and understand a surface. Slides, equations, and theory can sometimes get in the way. Each of these videos presents a single topic in just a few minutes. We take a concept down to the level of a simple drawing in real time, which provides an incredibly effective path to understanding.”

The Notepad Series departs from the typical web-based seminar content. “The Notepad Series flips this model upside down. The sessions are brief, informal, free, and there is no commitment or registration required for viewing.”

Malburg added that the videos serve as a catalyst for further training. “These videos elevate the basic knowledge level and make dedicated training/consulting more accessible and more effective.”
