Understand why roughness matters, how stylus (contact) and non-contact methods differ, and how to measure and interpret roughness reliably using standards and best practices.
This guide explains the fundamentals of surface roughness measurement and why it matters in real-world applications. It introduces key roughness concepts and terminology, compares contact (stylus) and non-contact measurement methods, and outlines when each approach is most appropriate.
Readers will also learn how to perform roughness measurements correctly using recognized standards and best practices. Step-by-step guidance covers setup, parameter selection, and result evaluation to ensure measurements are accurate, repeatable, and meaningful.
This document provides technicians and engineers with a clear understanding of the purpose, methods, and practical considerations involved in reliable surface roughness and topography analysis.
