Ra 3.2 basically mean the surfaces must be machined to a tolerance of 3.2micro metres
>
Ra 3.2 would mean a standard finish on a lathe or miller ie not a deliberate finishing (slow speed) cut.

Ra or Re was the ancient Egyptian sun god.
the touchstone of Ra for house of anubis is i believe on June 1 2013
This film, Ra One, was directed by Anubhav Sinha. It was released on our screens in October 2011.
There are no cities in Sweden large enough to have "city status" whos name starts with Ra.
vdi is Visual data index ,which is measured in the value of Ra for the roughness measurement.
average roughness, or Ra, are expressed as microinches or micrometers (aka microns). given that your value is '50', i'd assume that the units are microinches if you're talking about a polished surfaces. your best bet is to contact the source that gave you this value and confirm the units. Ra is not a unit of measurement; it is a quality that is measured. unfortunately, you will experience this dilema again and again.
20 ra is worse
i don't know because I'm suppose to answer it in my science project and can't figure it out.!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!thank you; for NONE of your HELP!!!>:[[[[
The Roughness Average (Ra) for a 6.35mm plate can vary based on the manufacturing process and surface treatment applied. Generally, a typical Ra value for machined steel surfaces ranges from 0.8 to 3.2 micrometers (μm), while polished surfaces can achieve Ra values as low as 0.1 to 0.4 μm. For specific applications, it is essential to consult the manufacturer's specifications or industry standards to determine the desired roughness for the plate.
In engineering terms, Ra is the arithmetic meaning for roughness of a surface, and is also referred to as arithmetic average.
Surface smoothness is typically measured in Ra (Average Roughness) or RMS (Root Mean Square) for engineering applications. These measurements give an indication of the fine details of a surface profile and are expressed in micrometers or inches. The smaller the Ra or RMS value, the smoother the surface.
what do you mean by Ra and Rz values
surface roughness tester is the machine which used to measure the roughness of the surface using probes... roughness is nothing but the frictional force applied by the surface to the adjacent surface.. if roughness increases the amount of frictional force increases..
Ra is the roughness of the surface used in engineering. Mu(greek letter)metres is one millionth of a metre. To put in perspective glass would be around Ra 0.1, polished chrome plating would be around Ra 0.3 so Ra 0.8 is still fairly smooth but a dull finish. You would just be able to feel the surface with your fingernail.
