Analysis reveals the impact of measurement area size on surface roughness in 42CrMo4 alloy steel, suggesting improved practices for precision machining.
Key Points
Different measurement areas significantly influence the reliability of surface roughness values, and a consistent measurement area yields better data.
Key roughness parameters like Sa and Sk stabilize after 5.5–6.0 mm, while Ssk and Sku stabilize around 5.0 mm during tests.
Cylindrical surfaces were machined under various parameters, comparing the effects of measurement area on surface topography analysis.
Improved metrological practices enhance surface integrity assessment in high-feed tangential turning of alloy steel.
