Modeling and Machining Complex Chamfers in Fusion 360!

[@cobraframebuilding]

You have made me very happy today. Boy could I have really used this 2 years ago.

[@bittech1]

Fantastic timing! Current project has a number of wide, sweeping chamfers so this could prove rather handy. Another really handy way of doing the chamfer in the first place is to use the variable fillet tool instead of pipe. This way you can adjust the thicknesses at points and have things vary whilst maintaining a pretty even edge. It's a shame we have to use these workarounds though, some of these features you would just expect to be present.

[@ksanalyticalsystems2438]

I've really been enjoying your build videos and how they combine my son's interest in PC building and my own interest in machining.

[@bittech1]

@@ksanalyticalsystems2438 That's awesome! It's looking like that overlap's set to keep growing too as more folks get into machining at home.

[@bucketbuster4077]

This is actually damn brilliant. So much model and CAM value in 12min.

[@trailinsight]

That was great. I know it's old, but I'm just getting into Fusion after years away from CAD. I'm dealing with this exact thing and your solutions made sooooo much sense. Thanks!

[@trailinsight]

Blend worked great! I didn't need to change the standard chamfer feature to a lofted surface because we only needed an edge-break between a cylinder/cylinder intersection, i.e. simple conic section. I image in your example you needed to rebuild this because of discontinuity in the chamfer feature's surface where it transitions from cyl/plane to cyl/cyl intersection curves. We're only doing a .01" edge break too. Anyways, thanks again!

[@antoniomateo486]

Once again another great video answering all my questions. I swear when I run into a F360 error I Google it with NYC CNC in the search 90% of the time you have done a video Thanks John!

[@zunuf]

Quite a few good tips in this video. I've used fusion for years and learned several new things. It's a shame many people fail to understand why the information you're sharing is useful for more than the exact example part you've created.

[@ROBRENZ]

Excellent John! ATB, Robin

[@ZPositive]

Damn fine work, John. I can tell you beat your head against the wall until the wall broke on this one. And then you hand off that hard earned knowledge for free. You are a good human. 🙂

[@Rustynutsdesigns]

So glad I found this! Have an interesting chamfer on a rifle chassis that I was stuck on how to handle and this should do nicely!

[@PM.al.whatmough]

Excellent video John!

[@FrancoCNC]

I wish I had the KZbin skills he has. Excellent teacher.

[@toast47624]

As almost always John. I have been trying to work out how to do a similar chamfer and been watching Fusion gurus and getting nowhere. Then I find this and bingo it's solved. Your main advantage is you are a machinist fist.

[@dav1dh0ff]

THANK YOU! I have spent many hours trying to figure this out.

[@williamhinrichs6558]

Well done! I use HSMworks for solidworks as my CAM, I've used it's "flow" toolpath for both chamfers and fillets like this, and it hasn't let me down this far. I'll have to look into blend, but also, I'll have to look into what solidworks could do to replicate the pipe creation and subsequent deletion + surface modeling stuff.

[@corasalin6730]

expert teaching as usual, great video !

[@ScroungerLee]

Excellent! And nice to hear “hi folks“ again :-)

[@ksanalyticalsystems2438]

Blend is amazing! So useful!

[@wyatt5391]

i do not have blend. Is this an extension?

[@anrmanufacturingltd4436]

Love how detailed this video is. The way you talk through the options at each stage of the process is really helpful. We utilise Solidcam / Solidworks for our direct-to-machine operations and design support services. CAD and PCB layout software is also utilised throughout the company, supporting production and design requirements.

[@eightmantis976]

Really great video but latest version of Fusion has gotten rid of the blend toolpath, so that is not nice. thanks for the help all the same I'm going to try some of the other toolpaths and see what will work.

[@eightmantis976]

never mind i guess thats part of the 1600/year manufacturing options that i cant afford right now

[@nottjonforest]

Hi John, I have been watching your channel for a while now and it has now made me decide to learn Fusion 360! I have now purchased this software on Subscription and wanted to know what is the best course to follow for the absolute beginner for machining parts using this Cad Cam? Something to get you up to speed and cutting metal relatively quickly. I have a lot of projects both milling only or turning with "C" & "Y" axis machining. I have been in the Precision Engineering sector for over twenty five years now so I am not a newbie to machining just to using this software :-) I am in Perth WA and we work in the metric system so the course would need to be for this! Any help is much appreciated, thanks Jon.

[@georgeroper9210]

Can you make some videos on the cad part and cam part together.

[@SuperYellowsubmarin]

I had difficulty making this work with Morph, and had success with Flow instead.

[@stevenAnschutz]

This type of feature feels like it would lend itself to a 5axis machine... is there not a 5 axis equivalent to trace that would work super easily?

[@lostinacrowd]

I wonder how this translates to Solidworks. Variable size fillet?

[@Anonymous-nn5wn]

Why I don't have the blend toolpath?

[@JonSturm]

Any reason you didn't try Flow? Since it doesn't use a projection it should have done the job even better. You likely could have even reduced the number of passes since the amount of material you are removing is so little.

[@mischiefmachinellc]

i could not get these tool paths to work AT ALL. I tried for 2 hours. Then i finally started to dig through my setup to see if there was something wrong. then FINALLY i decided to make a component inside of a part un selectable and boom! IT WORKED perfectly. I must have missed the whole DO NOT put additional components in your models memo. . . Are there any other weird things that will mess up cam like having a component in a part??????? Is there a video of how certain things can ruin your day in the manufacturing environments???????

[@SGT_Fon]

Recommendations for learning without actually owning a CNC? I'm an hour south of Albany, NY

[@chas1878]

Try Fusion360 as it's free for hobbyist use. Take a part and act like you would program it to machine it in reality. Use feeds and speeds that would be realistic. Do research on anything you don't know. Watch videos on cnc machining My recommendation: Edge Precision Its an amazing KZbin channel. His videos are made like he would explain you what he's doing as if you would stand next to him.

[@RobertPetrucha]

Check if you have any makerspaces around you. I've been using the CNC router at my local makerspace for half a year and learned a lot.

[@johnalexander2349]

Buy a 3018 CNC.

[@kamil19951]

Where did you get that BLEND toolpath from?

[@FrancoCNC]

It's a preview feature. kzbin.info/www/bejne/pGPaeqZng8l0o6c

[@pozalujstapodpishus3062]

так как сделать фаску в fusion360, никак?

[@billh308]

This seems like splitting hairs on a knats ass. But again, you only need to do it once for a part run...

[@dmbworks8094]

i do wish they would add the ability to do this with a normal chamfer tool from a sharp corner! **magic button

[@MysticalDork]

I mean, you can use a regular chamfer tool. It will look horrible though, because of the fixed chamfer angle on a variable angle part. I suppose one way around it would be to do the whole thing using a 5-axis machine, but that's a significant step up in machine, and in programming complexity.

[@wildin13]

I can't remember, do they have a variable fillet tool? If not I'm sure they will soon and you can use the same method but with a fillet instead, it does work, I've done it in mastercam and you would have thought I used a 5 axis to achieve.

[@RobertPetrucha]

@@wildin13 Yeah I think you could get a great result by doing a fillet with "radius type" set to "chord length" instead of creating the pipe, then follow along just the same with deleting and lofting in the surface workspace.

[@wildin13]

@@RobertPetrucha I don't think you'd even need to create lofted surfaces. If you're just after a clean and aesthetically pleasing edge break you could run the programs using the fillet. It would require less CAD work, no tiny splines that you might miss like in video as its all chain selected. Personally I actually prefer the fillet look to chamfers, smoother look and feel to them but chamfers are normally quicker to produce 🤷‍♂️

[@originalbigtee]

Already confused and struggling to follow along.. here's an ad! Thanks youtube

[@thegribbs]

You don't use an adblocker?

[@johngover1455]

Now if Autodesk would step back to 2007 and allow choice of colors for CAM simulation we might have something. Come on folks, green on green isn't great :-)

[@satchelsieniewicz738]

def not 45 degreees tho

[@bcbloc02]

An operation that seems simple but is very far from it!

[@thekaduu]

Just don't do it... Problem solved :P

[@OU81TWO]

Exactly. Being a machine designer I would never create features like this.
