Hey everyone
I have a job to do engraving the od of a wheel. I currently have a 4th
axis but haven't bolted a motor on it. I can suss this part though. And I
use fusion360 for cam.
I have never done 4th axis work before. And don't even know if anyone has
a linuxcnc post processor set up.
Are you going to be able to use the "wrap" feature of 2d tool paths in
fusion to get this done? Or are you a licensed/paying user? Autodesk has
really gutted the 4/5th axis cad from the free version.
I did some more complex milling a few months back and ended up buying a
4th license. If

I have a surface plate but its triple the weight of this mill.

I wonder if a replacement cup spline with an elastomeric part would work? Make
teeth that interlock at the side of the spline wall and the back plate, with a
thin filler of high durometer flexible urethane, bonded to the metal with
something like Smooth-On Ure-Bond II.

What do you need to engrave?

You'd want the rollers to have teeth matching the interior ribbed shape of the
spline.

That's the problem with the slotted aluminum table top. Very handy...
until you realize it's not flat and/or level.
For a small slotted aluminum bed that was flat, I'd probably try to

I've been pondering this for a while now, wondering if there's a design
shape that has been missed.
In terms of a fresh design, things that could be done;
- increase the length of the cup
- put cutouts in strategic places
- use a cone rather than a cup
- make the cup in more than one piece

I wonder if instead of machined spines, the cup could be made from a sheet
stamping with the splines simply crimped into the sheet. (Although that
wouldn't help Andy with making a homemade one.)

There is a variant design used in some of the HD systems that uses two
of the outer ring gears and a double-length cylindrical flexspline.
The outer rings have different numbers
