Surface Finish Notation for Machined Components
Correctly specifying finish is vital for CNC-produced components It guarantees the finished part fulfills functional and visual criteria Surface finish callouts are typically represented using the system known as the Surface Roughness Ra Reported in µm or inches, the metric indicates average irregularity magnitude.
Evaluate both finish smoothness targets and the operational application before specifying
In practice smoother finishes help where exact fits and close tolerances are essential
Textured surfaces may be selected to improve grip or frictional engagement
Leverage precise callout notation within drawings to indicate required finish Specify the Ra metric and note any secondary treatments or special machining steps.
Note that precise surface specifications contribute directly to production success
