Whenever you increase number of teeth you decrease space available for chips.
Also you increase cutting force on the tool.

Scientifically i must calculate volume of chips produced per revolution and compare it to the available clearance volume.

But because it is not possible, i go away simply by reducing chip-load.

Hello Zero_Divide:
Scientifically is there a way to build a formula to calculate fz
when the number of teeth is changed. How would the formula look?

There is no scientific formula.
I think i just reduce chipload by 10% or so for every tooth.
This is in fact what most tool manufacturers show on their charts.

Are you sure you are not building another calculator yourself?
