So....the formulas are:
IPM = RPM x IPR
IPR = Chip Load x Flutes = (.005" x 4) = .02"
Therefore:
IPM = (2000rpm) x (.02") = 40 IPM
So why should my cnc mill be capable of 100ipm + ?
What is a good maximum limit for IPM on an x3?

youve left out alot of data.
the size and type of cutter, along with the type of cutting and material being cut will impact the feed per tooth. for example 2 flute 1/2 emd mills can range from .001 recomended feed in HSS to .04" (not a typo) on some fancy carbide ones for aluminium cutting.
2000rpm is definitely a limiting factor though and with typical hss tooling 40ipm would be optimistic on cutters under 1/2". you can certainly force the machine faster (ive done that by accident), but the tool and workpiece wont thank you and neither will the gears in the spindle head.
