När ytfinhet diskuteras finns det i huvudsak fyra grupper: mycket grov, grov, medel och fin. Dessa grupper har intervallen Ra 25, Ra 12,5, Ra 6,3 och Ra 3,2, utöver dessa ytfinheter kan ytans grovhet vara finare, exempelvis en slipad yta, Ra 1,6 eller henad (honad) Ra 0,8.

Simply put, Ra is the average of a set of individual measurements of a surfaces peaks and valleys. Reveal the Ra formula for more insight.

The Ra on a #8 finish would be 0.025 (1) Ra. There are many other finishes available of course, but for bio-pharmaceutical use (injectables, otic solutions) 0.38 (15) Ra and electropolished is usually specified and is codified under BPE SF-4. Powder and tablet manufacturers may be able to use a slightly rougher surface of around 0.5 (20) Ra under the BPE SF-2 standards as it is not electropolished. Reducing Roughness Surface Finish Conversion Chart.

The following charts and tables convert surface finish or roughness between selected industry standard units. Where: Ra = Roughness, average in micro-meters & micro-inches. RMS = Root Mean Square in micro-inches. CLA = Center Line average in micro-inches. Rt = Roughness, total in microns. N = New ISO (Grade) Scale numbers.

Simply average the height across the microscopic peaks and valleys. Ra and RMS are both representations of surface roughness, but each is calculated differently.

A surface finish chart such as this could include the following parameters: The most commonly used parameter is Roughness Average (Ra). The methodology of measurement and what is measured when calculating Ra and Rz are quite different. This is critical to understand if you will not be paid for your parts because the Ra you measured is not in fact the Rz surface profile that customer specified.
