Factors Affecting Surface Roughness and How to Improve Surface Roughness

It is a topic you may not have thought much about, but determining surface roughness is important. You see, dozens of factors affecting your product’s service life can be influenced by surface roughness. The only real way to know what those factors are, and improve your surface roughness, is to know what they are. Today we’re going to look at some of them.

Improving thin-walled parts made by CNC Turning

Turning a small diameter hole inside a thin-walled part is best done with a spiral toolpath rather than a conventional straight axis toolpath. Spiral toolpaths use tighter paths to perform the cutting, causing less stress and chatter on the tool and allowing higher feed rates, resulting in a better finish. Additionally, the chip can be “caught” by the cutter’s rake face more effectively, meaning clogging is less likely. The result of all this is an improved surface finish and less tool wear.
