How big do you plan?
There's also a hefty carriage with a massive tool turret and motor to accelerate at dollar-earning rates, plus bed friction to overcome, in many cases. As well, the DOC and FPR in table 4 do not look much like production roughing cuts with TC tooling and flood coolant. The knurling gcode from earlier in the week would also require higher feed force than the feed of 180 microns per rev in table 4, I figure.
