RE: [CAD_CAM_EDM_DRO] reality check...

Erie,

Oh, ok. So you are gearing UP the motor.
Then you would be at

750.2 x 40/2.38= 12608 in oz
yielding

12608/.625= 20173 oz = 20173/16 = 1261 lbf.

If I am understanding you want to gear UP the motor
2.38 before a 40:1 gear DOWN to the rack pinion.

That seems pretty good- I misunderstood your gear ratio.
You might just consider a larger rack pinion to get you there
rather than a gear-up though. (increase radius by 2.38)

What is your motor inertia? It is good to check inertia ratio
as well.

les,
running a 2.38(motor) to 1 (gear box ratio), hence the division....
