Notation for Surface Finish on Machined Parts
Exact finish callout is important for CNC component manufacturing It ensures part compliance with operational and appearance standards Surface finish callouts are typically represented using the system known as the Surface Roughness Ra Shown in micrometers or inches, the measurement denotes typical roughness magnitude.
Weigh required surface smoothness against intended use when defining callouts
For instance a smooth surface finish might be preferred for parts that require tight tolerances or precise alignment
By contrast coarser finishes may be useful where additional grip or friction is desirable
Employ an unambiguous finish note on drawings to specify surface expectations Include both the Ra value along with any additional instructions such as machining processes or surface treatments.
