Surface Roughness Chart
Surface finish describes texture requirements for surfaces, including roughness (small defects), waviness (larger imperfections), and lay (pattern orientation). Symbols on technical drawings specify these textures and necessary manufacturing processes, helping to avoid extra costs and delays.
The following surface roughness comparison chart is an important guideline for engineers, enabling you to compare common surface roughness values for different manufacturing processes.
