HTML-код
- Опубликовано: 27 июл 2016
- This video tutorial walks through how to contain CAM toolpaths in Fusion 360! This is how you can machine parts larger than your CNC machine's travel or how to contain toolpaths if you are trying to machine specific areas!

More gold! I had stopped working on a particular cam setup when I ran into this. Thanks John!
wow saved my day John! Unreal easy thanks so much was getting worried when I got into this one project that id have a hard time separating profiles for limited travel on my machine,, super happy about this now!
Another great one John. This is great timing as I'm planning on starting on an oversize fixture plate for the 440. This is just what I needed.
Great trick to know. I'm getting ready to do an oversized piece, so this will go right to use! Thanks again John.
Fantastic help for us, right now! Got a large engine part that will require this step! Thanks!
Thanks John! I am actually working on a part where I have been struggling with this very issue!
This is the exact video I was looking for. No faffing around, just straight into it. Thanks :)
very nice solved a lot of problem's for many people .do more of these john . thanks
Thanks, needed to know how to do this - came direct to your vids to find out !
I was just wondering how to do this. Thanks so much!
Great tip! Thanks.
Thats a cool trick John !
Thank you! This is big man (no pun intended), much appreciated!
Nice tip. I use this technique a lot as well as creating separate bodies all in an effort to bend CAM to my will LOL.
IIRC, if you check "rest machining" and the previous tool's diameter it wouldn't extend out the toolpath for the adaptive after modifying your stock contour dimensions. Or you can drop a point and explicitly specify it as the operation's entry position under the "linking" tab
I was thinking about this very issue! I'm getting ready to pull the trigger on a Tormach and I have a few pieces that are too large for the machine. Thank you!
I like put all my cam sketches into a component named cam, also I put my stock model in there if I need one. Keeps things cleaner and then when you come back in 3 years to an old project you aren't trying to figuring out what the hell all these sketches are for!.
John,
Thanks for the vid! I'm using Fusion360 for shop drawings and 3D printing so far, but hoping to have a mill someday so it's all interesting. Any mill I get will be a small one due to space limitations, and I've been wondering about how to mill things in stages, so this was a great choice of subject for me. A related area is how to design things, like say a sign, so that it can be made in pieces and put together later. Been thinking dovetails, half-lap joints screwed or welded from the back, alignment dowel pins, and other ways to join pieces so it doesn't show from the front.

Hi. I have a part to manufacture with my stepcraft 420. My design is larger than working spaces of the machine on the both side of y and z axis. By this video ( thank you for it ) we leart how to work with y axis. But I need it with z axis too.
Great video John! Can you tell me (I might be missing something here) but, where do I set my tool locations? I mean, when I complete the first op, how do I know where to locate my tool? (home/begin position) In the simulation, it starts in a weird place, will this happen in the actual cut? I guess what I am asking is, how do I line up my tool for the next cut? I don't see an option..
The only think you didnt hit that I wanted to know is how do you reset the orgon/zero for each subsequent tool path to re touch off your machine?
2d long entry glitch makes sense, plunge outside of stock turned on? rather than helical ramp or similar?
Not a glitch! John told the software where there was stock so it had an open side to plunge outside. The toolpath isn't that smart.
Stock contours! Who knew? I have been trying to do this for a while but couldn't get it to recognize the sketch for a boundary. Thanks!
Is the machining boundary function only available for 3D operations? I tried to split some 2D contouring up into two sections, but the machining boundary checkbox is not available unless I try to do a 3D operation. Thanks for these great Fusion 360 videos!
For 2-d operations, you can make a sketch, show the sketch, and use that as one of the contours you select as the edge of the pocket.
John, I noticed that on your 2D operations the tool path started and stopped outside the boundary area you set with your sketch, how would you keep it in that boundary?
Set and adjust toolpaths to plunge.
Guessing they are currently set to plunge outside of stock.
There is also a dimension you can enter that will allow that entered amount outside the perimeter. Just set that to zero.
I am dieing to know how you could re-fixture 3 or 4 times and still make everything without a blending error!!
John, is there a way to model a L bracket in fusion and then have it lay flat so it could be cut on a plasma table?
you could with a parametric sketch profile until sheet metal arrives
Very interesting, thanks.
But also I think that this could get you some problems. When it say "stock" it really thinks, that the material is only there where you defined it. As you can see, it places the mill right besides the stock and then comes in from the side. If there's unmachined material on the side the CAM didn't know about, it's going to plunge the mill directly into the material. That can't be good...
I noticed that too...the lead in is going through unmachined stock. Is there hold-down avoidance in Fusion360? If so, maybe you could define hold downs in the areas to avoid and keep it from hitting stock outside of the defined perimeter of the area to machine.

Would very much like to see how it works on the Tormach. Possible?
+NYC CNC - I see, disappointed but hoping for real time demo later. Possibility?
And as previously stated, your go-getter attitude is catching and inspires me a lot, thanks man. :-)
A concern here seems to be where the tool enters. It's going to assume the area outside of the machining boundary is clear (i.e. no raw material there), and so it's very possible to rapid right into stock. I guess you just have to be extremely careful?
There's an additional option - tool containment. It lets you specify tool outside boundry, tool inside boundry, and tool centered on boundry.
not everywhere. i'm having the same problem, worked around it but it is a pain, when limiting the stock it assumes the one outside is gone and wants to plunge in. talking about 2d adaptive. theres tool containment in 3d, have to fool it in to working in one plane only.
Can you limit tool path to avoid locations (such as fixturing or clamps)? Instead of "only machine here" you specify "never go here".
I'd imagine setting up the "only machine here" partition around the clamps would work for this application. But I wouldn't be surprised if there was.
It's in the setup itself. You model the fixtures, check the 'fixtures' box in the setup, then select the fixtures.
having work sketches outside of components (sketches used for machining or nesting) makes it easier to change or delete them without changing the model as you can do it off the parent tryade and it won't affect the model. and you can use sketches for cut paths, it's a non documented fusion cam thing. I have only seen 3 vids doing this 2 are yours
agreed. it's definitely something I do
it's something that needs more info done on it,
Scott a new vid you could do
+daniel lyall well yeah. but doing CAM stuff at the top level of the assembly seems super logical to me. why would anyone go out of their way to make it more difficult?
A not getting what you mean.
but doing CAM stuff at the top level of the assembly seems super logical to me.
this is what I mean info for doing it this way it works and has not failed yet for me
Containmer??? :-)
I don't know if it's me, but there's a very annoying permanent hissing sound, like the mic gain is too high.
This does not work for 2D tool paths, just to let people know
Actually I got it to work with 2d contour just fyi worked great
in the 2d operation must select stock contours then highlight the box or profile u want, then go in and select the contours you want to machine
