Forces in X,Y and Z

[PotatoMill]

I have used vertical milling machines a few times but i'm always using automatic feed. So I guess I have no feeling for it. I do neither know the usual gearing ratio on the handles on a vertical mill.

However in statics, deflection is dependent on torque or force. In both conventional milling and climb milling there will be some forces. There will not be any deflection without it, hesne sources of backlash, rigidity, and stiffness. I'm thinking about designing a machine that potensially can do HS tool-paths, and without knowing the right variables for calculating deflecting it could easily become a overly expensive or a shitty machine.
