In this drawing it says that each groove is separated by 5deg. Each groove has a depth of .015", the radius of the contour is 0.47"
How do I measure the separation of each groove?
I think I solved it. The measurement between the grooves is from the midpoint of a groove to the edge of the next one:
This matches the drawing. But I would like to know if this is the standard way to measure distance between grooves.
