Fusion 360 Adaptive CAM Toolpath - How to Speed Up Calculation Time!

[@wildin13]

I use mastercam professionally as a tool maker and have similar problems when using "rest machining" due to the physical size of parts and complex geometries. Our work around (this would work perfect for this part) is to create "bounding geometry" to limit where the toolpath goes. We might break our parts into quarters and generate 4 identical toolpaths in different locations. Sounds weird but it takes less time to generate. This part could easily benefit from one small toolpath patterned around the part. *Edit* commented before seeing the end of the video

THANK YOU! Your videos are pure gold!!!! You've saved me a lot of time and effort!!!

With the 3d adaptive tool paths my go to is to first increase tolerance and smoothing to at least 75% my stock to leave. Smoothing should always be a bit less than the tolerance and when you add them together they should never be more than your radial stock to leave. This will allow you to run high speed toolpaths better even on an old machine without hsm like my 1998 haas vf3 but you must have a drip feed unit to compensate for the program size.

Awesome, thanks for showing this. Those pesky pocket selections get me every time.

[@jamespark_85machiningtv]

so diffirent 2 conditions. Very useful tip! i'm gonna use this tip to my work!

[@cedriceveleigh]

This video is super helpful. And thanks for showing millimeters. :)

[@ScroungerLee]

Excellent tips. This is why I love you guys!, btw you didn’t click the “lightbulb” to hide the model during simulation LOL.

[@terryk3118]

do you still offer the online classes?

[@rsilvers129]

The problem with making the stepdown large and the load small is that the first cut in a new area is always the full tool diameter. So, whatever stepdown you pick, it has to be able to work with a 100% load.

do fusion360 offer broaching programming?

[@Peccavi75]

Good stuff. Thanks!

So on your 2d profile you were saying it is a bottom up. Can you explain why you would select a bottom contour versus a top contour? I have been milling with a CNC router for my carbon fiber drone frames/parts. I am setting my mill for a fixed stock position WCS with a clearance from the work piece in it's fixture. I have my pass through set for -.5 to -1 mm for passing through the stock bottom. But as I am setting my tool paths I have been working off of stock top and selecting my profile/features from the model/stock top rather than the bottom. Hoping to start using the router for some aluminum stock to make some protective covers for my arms/motors but I need to get the tram on my machine zeroed better. Currently isnt a problem for when I do 1.5-6mm carbon fiber plate but it will rear it's issues when I start doing 3D machining.

[@Sicktrickintuner]

I believe he is referring to how you need to select the specific details of the cad model to tell the 2D where to work. As the other will look at the model and stock and take away what isn’t needed to get to the final results

[@dividingbyzerofpv6748]

@@Sicktrickintuner maybe I was missing it as a 2D adaptive versus a 2d Profile @14.10 And that is where seeing him select the bottom I am trying to determine how it is different where I would have selected the top of that profile. Wondering if he would still select the bottom on a 2d profile

[@ScottMoyse]

@@dividingbyzerofpv6748 yes. Because by default the selected geometry sets the depth of cut. Look at the default value for the bottom height on the heights tab. It's Selected contours. Which means you can cut to different Z depths with an the 2D toolpaths.

1:20 Assuming the benefit of doubt, that you only misspoke, .004" is .1mm, not 1mm. Other than that. Pretty good video. 4:28 [cough, cough] Fanuc controllers. Useless Robodrill. -_-

[@Steve_Just_Steve]

[cough, cough] "Pretty good video."

3:53 Fusion is hung? 😩

[@machetewutang]

In 360 everything is so simple. Please compare it to NX CAM.

[@mateuszwawak7437]

Yea.. But if we want to finish more complicated part with 3d SCALLOP / Shallow etc. In simulation taking looooong time... They must fix it as much possible. We wasting time...

[@Aumtechinnovation]

hi, bacteria breeds on the tramp oil and book and crannies, ours is a redox system which is a system incorporating multimedia metals and once the coolant passes through it the bacteria and fungi are 100% eliminated and the killing process just goes on forever, you just have to add good water for topping up and concentrates to maintain the concentration, if not inconvenient send me your email address I would send you the details of the system.

Looking

[@Verifraudreports]

could always just buy a decent CAD/CAM workstation $$
