BetaBetaBetaWorks out a knurl's grooves on a cylinder: how many fit at the pitch, the diameter that makes them divide it evenly, their depth and their angle to the axis.
Turn the cylinder to the corrected diameter before knurling; the pitch is in millimetres as DIN 82 names it. Example: 19.6 at pitch 0.8 -> 77 grooves on 19.608
The diameter, the pitch, the pattern and the unit
The grooves, the corrected diameter and the depth in unit, and the helix angle
The grooves of DIN 82 knurls on a cylinder, with no CAD kernel needed, in the unit asked for.
