Wrap ToolPath Orientation

[H2omatt]

I have seen a couple post on 2d contour wrap toolpath and tried some of there suggestions but not have any luck. I think the wrap tool path only puts the tool on the convex side of the of the surface. as you can see in the images I tried to offset the blades away from the origin but that did not help. 

Has anyone found a reliable way to flip tool orientation on wrap toolpath?? 

[H2omatt]

Anyone have any ideas? I am starting t try to cut the blades with multi-axis contour or swarf. My worry is I use a pocket clearing with wrap toolpath for roughing which is very helpful to make the part. I need to find a way to force fusion to flip tool orientation. 

Thought?

I can't tell from the image, but is hat shape Oval and not cylindrical? The wrapped feature will only work on a single radius to determine the wrap. 

[H2omatt]

The shape is cylindrical. Its basically a 120 degree "Pie Cut" out of cylinder  

[H2omatt]

So I got Swarf toolpath to work the right direction as a finishing operation. I just need to figure out roughing strategy, previously I used 2d pocket clearing with wrap toolpath. But I still have not found a way to change tool orientation.

Wrap function only works on convex side of cylinder.

Yeah that's what I found and it does make sense since its called "Wrap Toolpath" BUT it would be super helpful to be able to flip tool orientation and I know I'm not the first person to have this issue. 

Swarf seems to be the go to work-around but I'm working on the roughing and floor finishing strategy now...

At the glance, looking at first picture of your post, working on concave side of cylindrical shape with islands, I'd say you need to use multiple sections with ball end mill in tool orientation and 3D pocket, step down tool size and finish using 3D contour.

It looks like every raw of islands would require separate tool orientation to line it up with Z axis, draw sketches to use as stock boundaries and restrict tool path to each section.

I am working on the concave side. I'm trying to avoid having to do so many sketches. also I need the floor to have a smooth surface finishes it cant have any "cusps"  so I have to use a flat endmill. also keep in mind I'm using a 0.03" diameter endmill so i really cant go smaller. 

In the image you can see how I machined the mating rotor blades using 2d pocket and wrap toolpath. it was all convex cutting though. It worked really amazing!!

I was only referring to your first picture, one with concave cylinder side, looks like a lot of "fun" to me.

[H2omatt]

To be honest the convex version was fun because fusion360 laid down awesome toolpaths. The concave version would be fun too if I could use wrap toolpath on a concave surface.   

I'm going to submit a feature request to "Flip Orientation" when using wrap toolpath. We will see if it gains any traction...

Line formed long time ago on this one but it can't hurt to poke AD again.

Does anybody know if the changing something.

Because I need the same feature but in a diffrent application.

I'm getting an LYNX mill-turn and need to mill letters with an 1mm endmill on the outside of an cylindrical part.

Standard milling operations are not a problem, because there I can change the tool orientation.

But when I want to use an wrapped toolpath I, the option disappears and I had to do a new setup and switch my coordinate system around, but as you can imagine it's not that comfortable to set up 2 coordinate systems for OP1 just for one letter.

Would you be able to share your Fusion file here?

Hi @seth.madore ,

I attached the model, but I didn't save the CAM. It's just a demo part for training purpose as you will see.

My problem was to CAM it up as a lathe part and then do the 4th axis milling for the question and exclamation mark.

For the other milled surfaces, I used the tool orientation function, but I couldn't do that on the wrapped tool path.

Because I want to manufacture the Part to train myself at the whole process from the design to finished part.

I would love to get any advice on how to accomplish this.

Hi

For wrap toolpaths you cannot use tool orientation because the tool axis is always defined as perpendicular to the Wrap Cylinder

Basically the wrap cylinder determines the tool orientation, for a 4 axis machine the wrap cylinders axis must be parallel to the rotary axis of the machine

[Softbaer]

Hi,
But my problem is that it is a lathe part so I defined the front face of the part as the XY plane. Is there any solution then to do the 4th axis milling with my radial live tools?

[a.laasW8M6T]

Hi, the example I attached in that reply is a lathe setup with radial tool milling, If you look at that you will see it works fine

[Softbaer]

I'm so sorry I didn't recognize the attachment.
Of course you’re absolutely right, now I feel dump, I found out it was a counter selection problem by me. It tried to mill it from the inside out, that was the reason that it couldn’t calculate a toolpath.

Thank you so much for showing me the right way to do it.
