Camshaft comp cams bend or not

I think you will find that 0.0001 is impossible to achieve except for EDM.

Twenty years ago, when I work as an "in house" die maker, we had style of punch that was approx 6 inches long and 1.5 inches high, and was .3750 thick +.0000 -.0001, these were hand lapped on a surface plate with diamond lapping compound. Ask my fingers how they can remember this :)
 
0.0009 and 0.0007, 9 and 7 tenths respectively, is not too bad. My cousin is an engineering tech at a major manufacturing firm and have hundreds of CNC machine centers. He says that most of their customers tolerances are generally never spec'd out tighter than 0.0005 or 5 tenths. Anyone?

thats 9 and 7 10/1000ths
 
And 7 or 9 tenths is nothing to sweat on the cam bearing journals.
