: I "grabbed" (I am a hoarder) a copy of the xls file, (it seems to work fine with Libre Office too).
I had one more look at drawing and I think a quick and dirty approach would be ....
p.s. can a standard CNC lathe do this kind of work?
cut few contours stacked on top of each other with a T-slot cutter.
But of course that does not allow for a complete cam shaft, but only the 15 mm high cam parts. But I saw the drawing does not "insist" of a one piece part.
80/127 inch stock would be sufficient.
What happens to a reamed hole during hardening?
How are the cam lobes fixed to the 7mm shaft?
