5-axis simultanious: flat end mill perpendicular to surface

[Anonymous]

Hi guys,

evaluating the capabilities of the Fusion CAM module we're facing the problem that we haven't qutite found the correct milling strategy for our products. We're milling rather big parts - especially compared to the tool lengths. So our milling has to happen with the milling end perpendicular to the surface.

In Fusion the only process I understood to 5-axis mill complex surfaces would be to use swarf. However when processing large surfaces this doesn't make any sense.

So: is there any option to make swarf mill with the tip? (like to turn from tangential to perpendicular milling?)

Or is there any other option to utilize e.g. the 3D-Contour milling with the milling end perpendicular to the surface?

Best regards and thanks,

Nicolas.

Does it need to be continuous or will Tool Orientation work? If the latter it should be fairly straightforward. If you can mock  up a part (export as .F3D and share here) with this situation in mind perhaps we can find a way to make the continuous 5-axis paths work for you. I can't say I've tried this yet to be honest.

Hi,

Tool orientation will not do it I think - It has to be continuous. I will try to set up something similar.

Thanks for the quick response.

This would be it if the tool was oriented to the surface..

(and not do the occasional up/down in yellow) 🙂

The file is attached.

Try this....

Passes Tab - Sideways Tilt = 90

There's a video on this page that might show you some of the control options for Swarf.

It's actually in Video #2, but it probably wouldn't hurt to watch both of them.

Actually you may not want to use 90. That would put the center of the ball on the cutting face. It creates a zero Surface Speed condition. Try something between 60 and 80 degrees with multiple cuts.

@mike.mattera

The software won't let the user put it at 90° anyway. I have not been able to get an acceptable toolpath yet.

Hi guys,

so there is currently no solution on how to mill using the tip only? Kind of a pity, we will have to buy the CAM service then - the guys use Delcam Powermill which delivers good results.

Best regards,

Nicolas.

No, I don't believe there is a way to force this yet.

I would also say that Fusion is still in its infancy with regards to 5-axis and Delcam certainly is not and is likely a better solution for simultaneous movement at this point.

If you look on the Pocket NC website, you will see that they are able to do it by projecting at sketch onto the surface, and using muti axis contour.   I have attached some pictures from their page and my attempt to copy it.   In my attempt though, there are too many retracts.

Yes,

I've noticed this significant and lots of other updates in Fusion CAM. And you're right - now the desired feature has been implemented. Nice..

Best regards,

Nicolas.

I don't really think the problem is solved because its really cumbersome to project the sketch,etc.   In my example, I can get the tool to stay perpendicular to the surface, but I cannot figure out how Pocket NC (A machine I have ordered and love BTW) did what they did.   In my mimic of it, the tool retracts and starts in different locations (where the lines cross the "points").   I don't see how they got it to be a constantly smooth tool path and keep the tool down all the time.    I may be close, but I need some help on this one.

When I projected my sketch onto this surface, I cannot seem to get the lines to be one segment.   As you notice in the third picture, I have some red "points".   The tool will stop here and go to another location, etc.   I think once that is solved, then we are on our way to some pretty 5 axis machining.

Anyone have a solution for this? I don't see how to do it in 5 axis CAM.
