digitizing engine camshafts...

Another list I am reading has posts like the following:

Well of course it is easy for a machinist to determine the
max lift, and probably also the degree it occurs at.

But it strikes me that once we get cnc digitizing under
control we could put the cam in a rotary table on a mill
(or put the cam in a digitally controlled lathe spindle)
and digitize the profiles directly.
