I'm trying to determine how pc-dmis calculates profile of a cone using form and location. I though I seen somewhere on this board that someone posted how all the calculations for pc-dmis are made but cannot find it.
Here is why I'm confused:
Measured cone has 8 hits at 4 levels for a total of 32 (cone is only about 1/4" long).
I report on the profile (form and location) and get a devistion of .0038", but when I do a xyza report I get:
meas nominal
X = 0.0026 0.0000
Y = 0.0023 0.0000
Z = -.4068 -0.4031
A = 60.1807 60.0000
also, roundness of cone checks .0026 (does'nt it take this into account?)
It just seems like my profile deviation should be higher than it is.
I have a model, but I justed entered required information manually, X, Y, Z, A, diameter 1 and diameter 2.
Thanks,
