MILLING GEARS

thomas_covington

Could someone please shed some light on the subject of milling gears for me? I am wanting to mill a herringbone gear out of some pre-turned cylindrical stock. Has anyone attempted this or actually achieved this? attached is an example of what I am wanting to do

It may not be the exact size, but the feature history will show the best way to model up something like this.

I added the teeth as solids, but if cutting from stock, now that I think of it, it should be cut instead of solid sweeps.  Just the inverse profile would be created with the same steps however.

Are you looking for advice regarding milling herringbone gears on a milling machine, or modelling them in Onshape, or both?
