Hello @bmarkeyJ44PH
I am not entirely sure about what you are trying to achieve.
But let's be honest, I am completely sure that the machining will not give the expected result.
If you are trying to use some sort of multiaxis roughing, it cannot be done in FeatureCAM.
Surface roughing feature in FeatureCAM can have only one tool direction during the whole toolpath.
Defined by the tool axis tab, setting it to vertical, or normal to a single surface.
The logic used by the wrap functionality is pretty dumb.
The toolpath that had been calculated as a planar toolpath will be recalculated in order to bend it around a cylinder centered on the axis centerline. The tool will point to that centerline all along the line.
For example the classical toolpath is align with the Z axis this way
But the wrap toolpath will be bend to act like
BUT there is no additional work done on the toolpath, it's just a mathematical transformation AFTER the toolpath calculation.
If we look closely at your part, it should look like this
I have highlighted one edge of the part with this blue line.
But the simulation of the wrapped toolpath is giving that result:
It's clear that the part shape is distorted, according to the warp transformation, it's logical even if not desired.
Using the part compare feature in FeatureCAM here is the result;
Blue is excess material, red is gouge, the darker the color bigger is the problem.
Hence I don't think there is a rotational limit in the toolpath.
Wrap is not intended to keep the tool normal to each surface. It would be the purpose of a multiaxis roughing toolpath like the one available in the Fusion extension.
But FeatureCAM does not have that capability.
Regards.

That was very helpful, it makes a bit more sense now, thank you. I was pretty sure that I was trying to use wrap wrong. I've gone back over some of the materials left when we got our "training", and I think what I want to do is 4 axis simultaneous, but we can't seem to figure out how to make it do what we want.
What I'd like to do, is be able to hold this part in a vice, on a tombstone, and mill that curved interior surface out( pivot1.png). Since I know my COR, I should be able to do that, at least that's what I'd assume. If I can rotate while milling, then that bottom radius should be no problem, as long as I have tooling that reaches.
To me that's the whole purpose of having a 4axis, I just figured we weren't doing it right.
I know 4 axis simultaneous is available in FC, I have examples of it, thought not quite what I'm trying to do. We had thought it would be some form of surface milling, but as you said, there are no roughing strategies that incorporate 4axis.
So that all being said, I have a few follow up questions. Are you saying that it's not possible to do this part as 4axis simultaneous
, or just that it can't be done using surface milling since no 4 axis roughing are available? If it can be done, can you point me in the right direction, we're all stumped.
I'm going to attach the one example of 4 axis simultaneous from our training, it's not what I'm looking for but it makes me wonder if I just don't how to program this part ( 4 axis pdf ). I'm also going to attach another example, much simpler, but same thing(manifold.fm), how would this be done the "FC" way? I ended up just doing it with 3 setups, but again, that seems like more work than is needed.
Finally, which fusion plugin are you talking about? A plugin in Fusion, or a Fusion plugin in Featurecam?
Thank again, hopefully this all makes sense.
