An Overview of Surface Roughness Measurements: Choice of Technique and Analysis
Accurate characterization of surface texture is critical for manufacturing process control.
This webinar focuses on surface roughness measurements and analysis using two widely-employed methods—(1) contact methods using a stylus profilometer and (2) non-contact methods using a 3D optical profiler based on optical interferometric principles.
The full-length recording of this webinar is featured in our 3D Surface Measurement Knowledge Pack.
Webinar Summary
Assess surface roughness by contact and non-contact methods
Surface texture affects the performance and reliability of a wide range of products ranging from automobile components, consumer electronics, and photovoltaics to those employed in space applications. Roughness is the most commonly used parameter to characterize surface texture, consequently, understanding surface roughness measurement and analysis plays a key role in optimizing manufacturing processes and improving product quality.
This webinar focuses on answering the question "What are the methods for surface roughness measurement?" by presenting a detailed discussion of line profile roughness and areal roughness measurement using stylus and optical interferometry, respectively. This includes exploration of the most commonly asked questions about distinction/overlap in the line profile vs. areal roughness analysis.
