Found this guy in my research while working on a cnc mill design http://www.daycounter.com/Calculators/Lead-Screw-Force-Torque-Calculator.phtml Can anyone confirm it's accuracy? I was going to use it to see what the minimum torque my stepper motors needed in relation to tool forces.
I know this is really late, but I was searching for similar info and this helped me: Screw Jacks maybe this will help others in the future
