How to figure out what servo size you need

[replicapro]

When searching for servos there are so many options. I have a Sieg X3 and I have no idea what size servo to get for it. Is there a formula or a chart some where?

Does anyone have a suggestion as to what size servos the Sieg X3 would need.
The mill is currently lead screws, but ball screws will be added.
all screws are 5/8
The Z screw is 26" with gas piston support.
X and Y are 12" and 29"
4th axis turntable is 6"

What I need to know is should I be looking for 200 oz 400 oz etc.
Should I look for only nema 23 or 34 frame sizes?
max min volts amps
Min RPM
Should I order some of those US digital optical encoders?

I just dont know what would be under power and what would be over kill.

I couldnt understand how it worked

Look at www.homecnc.info, a little larger mill with 430 oz-in servos.
Look at camtronics, http://www.seanet.com/%7Edmauch/ which sells mill retrofits. Maybe he would have a suggestion.

I tried the software. It is not so difficult to use, however supplying reasonable values is the hardest. Try the leadscrew mechanism and supply the values.
