We have a spec. on a print that requires 1.6 Ra , what is this value in RMS?Jerry Linne
CNC Machine Shop - Anderson, South Carolina
Ra x 40 = RMS
1,6 x 40 = 64
so the value in RMS=64

There is no precise conversion possible from Ra to RMS, since they are two entirely different measurements. However, assuming a pure sine wave shape, the conversion would be Ra x 1.1 = RMS. This is probably close enough for most purposes.
