2D Contour broken into tiny segments?

[Anonymous]

Once again, I'm not seeing the logic here. I'm simply trying to cut along a curve or surface using the 2D Contour strategy. However, Fusion really sees this as a complex entity when it is just a curve. How do I adjust settings to help the software find a logical solution? In other software, this is automatic and very simple.

I assume the software believes I need a smaller tool to accomplish this even though it is completely unnecessary. The Z levels are such that any size tool up to 1/2" diameter could achieve the results needed. I have tried many other strategies to clear these areas and everything ignores the area leaving it mostly unmachined in the end. I am not going to set up a 1/16" diameter tool to clear these flats when a 1/2" or 1/4" can easily do the job. It would be faster to draw a line and engrave than to find a solution here, which again has me scratching my head. How can this be so difficult?

It's going to be pretty much impossible to help without files to look at, we don't have a clue how you have anything setup.

Really? You don't know enough about the software to point me in the right direction? If I saw this problem in RhinoCAM, I would know which parameters need to be adjusted.

I'm with HughesTooling. I have never seen 2D Contour do this. Are you sure it's not 3D Contour?

All of these contour surfaces are the exact same Z level and they are above the surrounding material, which would theoretically allow them to be cut. I designed it that way for this very reason. The only solution appears to be the use of a tiny endmill even though there's plenty of clearance for larger tools.

Can you post screenshots of your operation parameters, especially the geometry selection?

your not going to be able to get much help without putting more info up other wise everyone will just be guessing if you wont you can invite someone in to help and if you wont them to sign a nda so thay can help they will most people that will help have 00 of hours under there belt doing nda work

I have posted screen shots of everything related to this part and my issues creating tool paths. I don't know what else I can include.

I'm pretty sure the solution is to use a different CAM system. Problem solved!

Please include the same information for this toolpath that you have for the pocket operation.

Conversely, if you can create a dummy part (as has been suggested elsewhere) and share it here, you can probably get 2-3 people to all check it out.

Fusion 180 update...

Yes, I said 180 as I have turned a corner or two thanks to Al and Curt with Autodesk. With their patient assistance through a GoToMeeting session, we discovered the issues plaguing my CAM progress.

It turns out that Fusion was doing really weird things that are not normal or useful because my part was imported from Rhinoceros as surfaces and solids. After converting everything to stitched solids and minimizing bodies, everything worked right away. I can now predictably create slots with the pocket strategy and contours along curves and surfaces.

I have to say that Fusion is truly awesome software once everything is working properly!

I'm running two complex test parts this week, one programmed in Fusion 360 CAM and the other in RhinoCAM, which I have used successfully for many years. I'll update you on the results.

Thank you again to Curt, Al and everyone who chimed in the past two days on all three threads.

you cant go wrong when curt and al help I just wish curt would do some more vids
