the methodology of measurement and what is measured 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.

How do you convert Ra Value To Rz Value?
what do you mean by Ra and Rz values
Ra equals 0.8 µm?
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.
Which is rougher 15 Ra or 20 Ra Ra is Roughness average a term used in passivation?
20 ra is worse
Are hours a ratio or interval level of measurement?
An hour is a unit of measurement. A ratio is a comparison of similar things. You can use hours within a ratio showing something over a measurement of time. For example as speed (25 miles/kilometers per hour) or hourly wages ($7.25 per hour). An hour can also be a measurement of Right Ascension. This is a measure timing the passage of objects in the sky across the meridian as the Earth rotates. RA is measured in hours, minutes, and seconds.
What does running average of all grades mean?
The first running average is the first grade. The second running average (RA) is the average of the first two grades, the third RA is the average of the first three grades and so on.

What is the degree f surface smoothness?
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 is ra and rz surface finish?
what is Rz and Ra urface finish?
What is the value of Ra?
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!!!>:[[[[
What is difference between Ra and Rz values?
Ra is Indian standard whereas Rz is DIN standard
What is vdi?
vdi is Visual data index ,which is measured in the value of Ra for the roughness measurement.
What is means by RA?
In engineering terms, Ra is the arithmetic meaning for roughness of a surface, and is also referred to as arithmetic average.
What value unit to determined the smoothness of a metal surface?
The roughness of a metal surface is typically measured in units of micrometers (µm), or sometimes in Ra values as per ISO standards. These metrics help quantify the deviations from an ideal surface profile, indicating the smoothness of the metal surface. Advanced techniques like profilometers or interferometers are commonly used for precise measurements.
Ra equals 0.8 µm?
