So, if your machine has a 200 Lb table, and the leadscrew
were to produce 1000 Lbs linear force,
it would accelerate at 5 G.
This is a simplified calculation, it doesn't account for rotary inertia of
ballscrew and other rotary parts.
You need to reduce that rotary inertia to a mass and add it to the table
mass. And that will be a pretty significant amount, particularly if the
ballscrew is long and massive.
Yes, quite true. But, in fact, the ballscrew is
insignificant compared to the MOTOR mass.
But, this was just a ballpark figure.
