And this is why I love watching these. I've been dealing with a CAM issue myself where I was containing the toolpath and creating these rounded inner edge cuts, and now I know how to fix my toolpaths without having to resort to unnecessary sketches. Thanks for this! Maybe next time I won't get stuck with a delayed flight and might actually be able to make the next open house.
I have no idea where you unearth the details of how these operations are accomplished, but I'm glad that you do! Thanks again for sharing all of these tips with us.
You explained the differences between closed vs open toolpaths, then used a closed path and extended your patch to compensate. Great bit of knowledge though! Learned about open/closed toolpaths, that you can pattern cam ops, and what that form check box is for! Thanks for making these great vids!
What about 4th axis machining on a rectangular stock? I can see round stock being fairly easy, but I wonder if there's extr steps to not crash the spindle or if fusion would recognize it from the stock sizing. Thank you for these great videos.
For those of you trying to use this tutorial to machine on a 4 axis rotary, this tool path will not work, for some reason on fusion 360 when using a rotary your cutter will not leave the center of the shaft you are cutting. so cutting a spline like this will get it close but there will still be stock on the walls.
Great series! I would love to see some simple 5th axis work. For instance, machining a simple pocket that is cone shaped or round on the bottom and square on top! thanks!
Are you serious? We have to create patches (which are really surfaces). Surfaces have no thickness so it's odd that Autodesk would call these patches. So we use a "trick" and make a 0 offset surface. Sorry, I meant a 0 offset "patch". Then we make more "patches". Then we have to split and modify the "patches". Then we delete "patches". Then we have to extend the ends of all patches to get the tool path to cut all the material at the ends. All this just to get simple 4 axis wrap tool path? Yikes!!! You mentioned that we "wouldn't know it" a few times in this video. Why is that? Why as end users would we not know it? No, I am not a MasterCAM, GibbCAM, EdgeCAM, Surfware, HSM User. I just have been using CAD/CAM for over 30 years. Not an expert, just saying this looks like a lot of work for simple 4 axis wrap tool path.
This is great stuff John, but I am kinda horrified at the mental gymnastics required to do something so simple. Are other cam packages for 4th axis so obtuse in their operations ?
Great video! But Yikes! That's a lot of work for simple 4 axis wrap tool path. I am not completely familiar with Fusion 360 so your videos are very useful. Do you need solid models for all tool paths in Fusion 360?
I have to cut multiple parts in fusion on the fourth axis and do not have enough material to do one offs each time. Why is there no feature for slotting in between parts? Any suggestions as to how I should go about this?
I think its beacuse fusion is kinda of a "free ware" trash. It's entry level cam for us who don't have the molla for master cam. I use it and it works but it's allways allot of work around and messing around. It's frustrating when you're a toolmaker who has to fight the urge to just go do it in the manual, or just caveman program it (g and m codes on a note pad)
Joshua Wentworth Sketches are 2 dimensional and the face of this shaft is curved. It would have been possible to excuse a sketched line as a surface but that would pretty much give you the same result as using patch.
Hey John. Just curious if you are planning on having something particularly super interesting and extra special for FF100. Just for no other reason than it being a notable number like 100. :)
Any way to mimic turning the full revolve? I watched the full video, and it does seem that you say it's not possible yet, but Its been a few months since this was posted and some new features have been added. I can sort of get my simulation to show what I'm looking to accomplish, but it won't post the code.
Hi John, I'm looking at a 1100 or 770 will be doing pistol slide work and knife making, would like 4th axis also. Seems like the 1100 would be the way to go....Any disadvantage to the slower spindle speed? didn't look like you had any problems engraving or using small tooling in your 1100 videos. Thanks between you and Grimsmo I have watched months of videos LOL
The wrap tool path should adjust X Y Z A correctly to get those radial-plane walls and curved floors. In the machine the looping adaptive should only consist of X (left-right) and A (up-down) motion, lead in in Z notwithstanding. The machine shouldn't move in Y!
this is the problem with sides and wrapping. as the tool doesn't move in the Y, the sides will be parallel with the cutter. Once its finished with the wrap you would need to go back in with a 2.5d path, but orientate the Z with the wall. then take a cut down the length of the part, then back up the other side. then do a circular pattern to clean up the other sides. Hope that made sense.
I see what you mean. The machine would have to move in Y the diameter of the tool cylinder between the two walls. Otherwise the part couldn't rotate to put each wall plane aligned up without colliding with the tool. But assuming these wall planes are radial outward it's important to remember they aren't supposed to be parallel to each other.

Thanks John S. Really great tutorial. I am just adding 4th axis to my Tormach 1100 S3. This really helps!
Very well done tutorial. These just keep getting cleaner and cleaner, nice job!

This is awesome!! Love that you are getting into the fourth stuff!
really hope they fix this in an update
cause this is one janky setup for for doing stuff like this
Fantastic video, thank you!
That was wild! Great explanation John.
it would be nice to see the Setup settings, is it milling or mill-turn?. I cant understand which way which axis looks
Are you serious?

Sweet lightsaber!
i was thinking the same thing actually

Do you need solid models for all tool paths in Fusion 360?
Fantastic!
Very interesting and love 4th axis dont run it but still good video
this seems to be a work around... is there not a way to use the model an play with the parameters?

How do you machine a 3D object like a toy car, on the A-axis using A rotation?
Hello please also work on the Powermill axis.
If i remember correctly you can make a sketch in the model and select it to contain the toolpath without using patch?
Joshua Wentworth Sketches are 2 dimensional and the face of this shaft is curved. It would have been possible to excuse a sketched line as a surface but that would pretty much give you the same result as using patch.
Hey John. Just curious if you are planning on having something particularly super interesting and extra special for FF100. Just for no other reason than it being a notable number like 100. :)
John, does fusion still have no y offset for rapping meaning it willStill leave or remove stock from the solid model?
time for an update. There is no patch tab :D

Would you be kind enough to post a small piece of 4th axis code , just for testing on a Taig 3000 CNC MILL

Great video, can you do a video for 4th axis in Fusion for non uniform cylinder like vase?
Currently a shape like a vase isn't supported. You can only specify one wrap diameter at this time.
Mechanical Advantage thanks for your reply, I hope Autodesk will add it to Fusion 360 to stay with one program.
How to make a male strip to fit that ?
What the hell is the shadowy thing stuck to your patch (and tangent to the surface)?
But the side walls aren't angled now, how would you do that?
The wrap tool path should adjust X Y Z A correctly to get those radial-plane walls and curved floors. In the machine the looping adaptive should only consist of X (left-right) and A (up-down) motion, lead in in Z notwithstanding. The machine shouldn't move in Y!
But it should, else it wouldn't get the sidewalls of the keys (or whatever you call them) right. They wouldn't be parallel to eachother.
this is the problem with sides and wrapping. as the tool doesn't move in the Y, the sides will be parallel with the cutter. Once its finished with the wrap you would need to go back in with a 2.5d path, but orientate the Z with the wall. then take a cut down the length of the part, then back up the other side. then do a circular pattern to clean up the other sides.

Why not more Haas videos ☹️
no I know! I want to see that VF2SS runnin'
