John, I really enjoyed contributing to this video! Your Transistion Type on your Linking Moves tab need to be changed to "Shortest Path" or "Straight Line" for them to NOT put out a ton of code on wasted moves
all your videos are gone ?
John, those linking moves are the transitions and you would have to change transition type to shortest path to minimize them.
Great video - I love how you are giving credit where credit is due!
Thanks John and Seth, great video. Adding that to the brain housing group!
Good info, cleaning up the ops is always good to see ways it is done.
Ideally you should have had that toolpath cut from the bottom up, so you are not doing the majority of the cutting with the center of the ball mill. Do this by rotating the parallel path by 180 Degrees in the passes tab (pass direction). Better finish, better endmill life... etc etc. Great Video though.
This patch thing took me so long to figure out on my own. I use it on pretty much every part I machine now. Linking trick is something Im gonna have to try.
One way I've had success doing that same thing was to project the edge of that fillet on a new sketch on the side perpendicular to the fillet. Then in patch you can select that projected edge and extrude which creates a surface. You can change setting to "Two Ways" to extrude it in the other direction as well. This way you don't have all that extra geometry inside your design to deal with.
4:55 made my day... thanks
Is it still not possible to extend the toolpath in 2020 using geometrie, passes or linking?
Hey John, thanks so much for a wonderful video. It helped me a lot and saved my project
John,
At work I use NX9 and it refers to what you describe as "zero thickness surfaces" as sheet bodies.
You create a sketch that has open geometry. You then extrude it by whatever distance you want. This gives a sheet of zero thickness. I regularly then use the subtract function to remove material, leaving the geometry I want.
I tried performing this in Fusion and it won't allow me to select open geometry in the Pull or Extrude functions.

I'll have to try the tip on linking. I've got a 1991 Leblond Makino with the Fanuc O-M control. I have to drip feed most programs that have a lot of adaptive stuff or 3D. One thing mine does is slow down the feed on the tight radii in between parallel passes. Can't quite find the parameter for that one.
Good stuff Seth is my go to guy
Had to check. You're right. There is no tangential extension parameter for surfacing ops.
Looks like the only other way around it is to turn contact points off, turn boundary to outside containment and use avoid/touch and slope angles to make it avoid other surfaces.
It does seem to automatically add in some extension to fully clear the surface. So there's an expression hidden somewhere controlling it, but looks like it's in the background, nothing that's user changeable.
there is 'fragmentExtensionDistance' that accomplish what John did in the video without having to make a surface..
Yes. Bu where can you change that? And is it per toolpath or a global change across all paths?
per toolpath, it's just an advanced parameter that hides on the passes tab.. In fusion, I don't think there's a 'show advanced' option, so you'd need to edit it through 'compare and edit'
Rob... It would have to violate the containment boundary to have an effect wouldn't it? Whenever I've tried to muck about with it, It hasn't changed the toolpath.
Also where is the Show advanced option? I swear I've seen it somewhere before, but I can't find it.
Great intro to patches. Thx.
Thank you
it is unfortunate that as of June 2022 they have not built this intelligence into F360 CAM tool paths yet.
Fanuc still using paper tape? 😁
Could it work also with set "tool outside boundary" instead of creating a patch?
Beltra .KTM
Yes. But it will try and do the vertical wall sections as well, so you'd have to control it with slope limits and avoid surfaces.
Awesome! Thanks! i was just unstitching everything lol
Sadly did not work for me.... Cam does not see it and generates an empty tool path ..
Pl make new video for patch command on mould & dies.
NYC CNC I saw the work holding part that you made on AVE's channel, are you open to selling me one of those?

The mini pallets? He has them for sale on his site.

Occams Sawzall thank you :)
Hi guys i'm 48 and I need to find a new life skill. My dad was a machine repair man and everything needs a part made!
I was unsubbed from your channel for like 2 months I didn't even realise and just though maybe he's not making videos right now I have so much to chatch up on now 😂
welcome back!
Fanuc controllers are terrible. they don't offer a lot of memory. Is there any possible legit reason for it, or are they just cheap bastards? lol!
Fanuc controllers work great..are super reliable and for 3D you can drip feed them so a large memory isn't needed..less to go wrong..for standard work the memory is usually ample..for 3d drip feeding works great..if it aint broke don't fix it!
Drip feeding leads to far more possibly going wrong..
