Cool.

Your avatar reminds me of the early days of Mach 3 Turn. A few of us were wanting threading, but A. F. kept producing improvements and features until someone said "you don't have a Turn program until it threads". It must have been the right 2X4; we got threading.

Hi Art,
Steps at the bottom radii don't matter, and at the top the shaving should be fine.
But I don't understand your statement regarding the walls being straightened by the wall routine, I take that to mean flattened. The only way I get any taper on the walls at all is to make small depth ...

Okay, I see.
With a flat mill you get a stepped wall.
I might try making one with this method but I think I'll go back to making a full profile cutter, similar to a gear cutter.
Many thanks though, very cool program Art.

Here's another shot with the color changed slightly. Only the bright green are cuts.

That's not correct Art. I am watching it with the slider all the way down.
Anyway, with the sim zoomed in so it just envelops the action, and tilted for the best observation I have watched what is happening; watched it for quite a while, and I don't see the walls of the pulley being cut.
During ...

Okay, I confirm they are moves outside the part/pulley.
I'm not sure I see the wall being cut, even at the slowest speed it is hard to see. I have tangential and rooting turned on.
I see it cut to the root, but then it looks like it goes to cutting/shaving the tiny radius at the upper edge.
If I ...

I understand. I'm looking at it in 2D, I'll try to get a good 3D view. Thanks. Ozzie

Art,
Project file? Where, how?

So what parameter should I change to make it work?
I tried putting a clearance in and then it says the tool is too big???????
