This thing feels so rough! How rough is it?<\/p>\n\n\n\n

This thing feels so smooth! And what about its roughness?<\/p>\n\n\n\n

In the pursuit of precision within industrial fields, such expressions are akin to saying, “The sea is blue.” Yet, the shade of blue in your mind may differ from mine. To address this variability and improve yield rates, the definition of surface roughness was established in the 1940s. After numerous revisions, it eventually became the industrial standard that we rely on today.<\/p>\n\n\n\n

*Ra, Rz, and Rmax are often used in the industrial field, and this article will focus on “Introduction to Surface Roughness – Line Roughness”, so if you want to understand the differences between SA and RA, please refer to this section>>> for the differences between RA and SA<\/a><\/p>\n\n\n\n
