Thanks, good idea! I had a look through the sandvik catalogue which had some great stuff in it. Still couldn't come up with a formula for milling force (maybe I'm just dense). I did find a formula which I think will work here:

Attachment 245102

Knowing the max horsepower we can get from our machines is 1HP (at least in stock form) and recommended SFM for steel using a HSS endmill is 70 the formula reads as:

(1HP x 75% x 33,000)/70 = 353 lbs

This chart from G Wizard shows vectors of forces from different milling actions:



I'll update with this new force and I need to add a torque force to the head / Z saddle joint which is missing right now.

Does this sound right?
