Measurement Tutorials from Digital Metrology provide metrology training in surface roughness measurement, 3D surface texture measurement and other aspects of shop metrology

Digital Metrology provides measurement training as well as consulting services and measurement software. The metrology tutorials below are all intended to help users learn aspects of measurement such as 2D roughness and waviness, 3D surface texture, roundness, etc.

All of the documents can be read online or downloaded as “PDF” files. You can obtain a free copy of Adobe’s PDF Reader here.

Areal Surface Texture Analysis Areal Surface Texture Analysis for Both the Lab and the Engineer's Desk

This tutorial discusses a step-by-step and visual approach to surface texture analysis. The process, which is the basis of the OmniSurf3D software, allows designers, managers, process engineers and lab staff to explore, understand and communicate surface texture. By providing a common language for surface texture analysis, OmniSurf3D helps everyone involved to improve component performance.
