Ok So Ive been slowly learning F-60 of the last few months. I have manage to make a couple projects but for the life of me I cant remember how to set up hights or maybe passes I think?. When I run the simulation. the bit always boars down to the lowest depths and works it way up I need it to go from the top down to the bottom making multi passes. I did it once but darn if it alluded me I though I saw a vide on youtube on how to do this but I think I'm asking the wrong question to get a correct answer. Any help would be great pointing me in the correct direction.
Autodesk changed the way that they specify the heights fairly recently that may be causing confusion - this video goes through it: Otherwise: What operations are you talking about? The first picture is some sort of contouring operation, the second is some sort of boring operation (not sure about the 3rd!) What exact toolpaths are you using? If you export your F360 project and attach it here, I'll have a look.
Im trying to cut around the project starting from top to bottom multi passes when I simulate it it dives to the bottom and lack of a better work GO's for it. and for the boring same thing happens it dives to the bottom working its way out I want to start at the top working my way in with multi passes Dose that make sense LOL Sorry trying to make sense of this
What you're asking for makes sense, but there aren't any tool paths in that file - can you attach the version including the toolpaths/operations that you're having problems with and I'll take a look.
I think I got the Boring one correct this time but the the milling the edge out of the material. Thank you for your help
No worries Easy enough to sort out with sight of your file, but ran out of time yesterday. The 2D contour path can be quite confusing as it uses 'roughing' to mean different things in different places. In short, you need to set the *roughing* stepdown in the 2D Contour path to be the stepdown that you want, but keep 'roughing passes' un-checked ("roughing passes" in this case work sideways towards the contour). The stock is 0.54" thick, so can easily be cut through without exceeding the "max roughing stepdown" value of ~0.56". There are 4 finishing stepdowns of 0.001" each, so normally the first roughing depth would be 0.54" - (4 x 0.001") = 0.5". However "rough final" is checked, so the first pass is actually the full thickness of the stock and the "finishing" stepdowns won't remove any more material (as you are seeing!) To cut out the part in multiple passes (without any finishing operation), set the "Max Roughing Stepdown" to (say) 0.1", and set "Finishing Stepdowns" to zero: If I'm cutting a profile like this, I often want to cut it out with a number of gradually deeper passes, then run around the whole part again, taking a light cut at full depth. To do this, you need to set the "Stepover" to the width of that final finishing path (0.004" say), enable "Roughing Passes" and select one roughing pass, check "Rough Final" and "Finish only at Final Depth". Hope that helps - the simulate command is your best friend Feel free to ask again if there's anything you don't understand.
Ok well WOW thats a lot of information I've been using Esael a lot it dose all that for you but im finding its not very adaptive to complex or certain projects, guess Ive got a lot of learning to do But Thank you very much very informative. This will help very much.
It *is* a huge learning curve, but the capability of the software is mind-boggling. FWIW, I think the 'Mechanical Advantage' videos on Youtube are very good for understanding F360 CAM operations (but there are also loads of other channels on the same topic). (Link) ETA: Just spotted a silly error in my post: 0.54" - (4 x 0.001") = 0.536" The logic still stands though.
I followed the NYCCNC channel's 'fusion Friday' videos for years, focussed short dives into specific things, rather than 2 hour long videos that try to cover everything
Videos will help a lot I prefer the videos I just tag along doing the same thing there doing kind of like a hands on approach to learning
