I've been banging my head against a wall for weeks trying to solve this then I found your video and all sorted in a couple of minutes - brilliant, thanks John! 😎👍
Being able to use expressions when entering parameters is an awesome feature, and definitely makes a program a higher-order product. Those same expressions in John's web page are the ones used in the internal programming of, and the API to Fusion360. Being able to use expressions is cool. Having an API is even better.
Hi Jhon, Nice video and information, A good Application to this is when you make an internal big Thread or helix in two halves mold by machine it on CNC mill, a ball end mill won't be able to reach the starting and ending of the helix because of the undercut. Thank you
John, I am curious do you ever go back and try to redo cam work, and see of Fusion fixed some of these problems ??? I mean you should not have to do all those additional steps to machine one surface but its great that you show us this and expand on it.
Why not just use a slope contain vs editing the tool path height? I whipped a quick model and cam'ed it using touch surfaces and slope contain and it seemed to generate virtually identical results.
Hi John, huge thank for all your UA-cam Tutorials, love it.. as a CNC beginner your helped a lot in my attemps, i use an 10 Year old PC with Fusion, sometimes its too slow.. can you make a vid about your PC Equipment and your recommends for better working flow ? thx and best regards Ilker
How do you use cutter comp with this?? I find fusion to be extremely frustrating when trying to use wear cutter comp. I just figured out if you want it to input the G41 code in your 2D contor you have to select multiple finish passes. Why would it even give you the option just to not use it? I am quite new, I’ve done a few programs for work and made good parts but it’s very frustrating at times.
I don't understand Fusion's bogus logic. If you checked avoid/touch surface, and selected a single surface, how hard could it possibly be for the program to just get the tool to make contact with the said surface and be done?
technically as it was wrapping around the sides it still was only touching that desired surface since the center point of the radius of the lead-in was on the edge of the part so no cutting on the sides would be done.
Do you have a general impression of how to pair the radius of tool to the radius of surface? Is a 1" tool in a 1" surface bad? Too radius half surface radius? What cutter diameter is just right for feature radius?
Brian Clark largest tool you can fit is generally a good rule. So if you need to make a .5” radius, a single pass with a 1” ball endmill is perfectly acceptable. Basically the fewer step overs required to make the surface the better
Can’t you extend it under linking moves to have it make a longer lead in and lead out rather than creating a surface? Also change the direction of them? I don’t have it open right now to check.
I prefer to use avoid faces than touch faces cause of the reason you just showed. I click avoid faces and pick all the faces that I do not want tool to touch. But you need to input a very low surface clearance.
I wish someone would put out a list of expression values that is *actually complete*! A complete list of values that can be used in post processors would be nice too.
john, Im looking for some assistance. I need to select hundreds of the same pocket to machine. rather than selecting every pocket does fusion have a solution for this similar to the drilling operation where you select drill all same dia etc. thanks!
That would be a great feature! Although it's not quite what you're looking for, it's possible that using a pattern would be an option (depending on how regular your pockets are). Create the toolpath(s) you need for one of the pockets, right click on it in the CAM feature tree, and select "Add to New Pattern". If patterning is an option, hopefully this'll get you rolling. In the pattern dialog there is an option in the Pattern Type drop-down list called "Component pattern". If you happened to have hundreds of pockets because you have hundreds of components in an assembly, this could save you a ton of time!

P.S. thank you for posting these fusion videos, I would not have gotten as far as I have with fusion if it wasn’t for the videos you post.

Thank you
The patch trick helped me a looot thank you very much
The uppercase/lowercase parameter names is called camelCase. It’s used in most programming. It’s origins are way way before python.

I often add some "dummy" patch/surface for having my CNC going just on the good part! Great tips as usual, love the CornerRadius tips!
It help me so much thanks you!

I actually tried to do this recently and couldn't figure it out. Thanks so much for the enlightenment!
I don't understand Fusion's bogus logic. If you checked avoid/touch surface, and selected a single surface, how hard could it possibly be for the program to just get the tool to make contact with the said surface and be done?
The label is "avoid/touch" as in either avoid or touch a surface. Avoid is default, to get touch, the additional radio button needs to be checked.
technically as it was wrapping around the sides it still was only touching that desired surface since the center point of the radius of the lead-in was on the edge of the part so no cutting on the sides would be done.
Is there a way to get the contour to cut in vertical paths? More like a parallel process, but I can't get it to work on this example.

Pretty sure that doesn't straighten out the linking moves. Seem to remember struggling with it myself.
John, thanks again for doing this on the open forum. The phone case milled out perfectly.

Question, will this strategy work with both your Haas and Tormach 1100?

F360 should add the list to the app, if they're are not already.. and if they are, where are they?
