Surface Texture Analysis

Definition

Surface texture analysis refers to the study of the micro-geometry of surfaces, which includes measuring and characterizing surface roughness, waviness, and lay. This analysis is critical because the texture of a surface can significantly affect friction, wear, and overall performance in engineering applications. Understanding surface texture helps in predicting how materials will behave under various conditions, particularly during processes such as grinding and polishing.
