WRAP TOOLPATH AROUNG NON CYLINDRICAL FACE

[banddspindles]

How WOULD i WRAP TOOL PATH TO PERFORM CHAMFER WITH 2D CONTOUR ON THIS PART?  THE RED PART IS NOT CYLINDRICAL, BUT A OCTAGON IN SHAPE.

[banddspindles]

I FIGURED THAT, BUT I AM USING A 4TH AXIS. I WOULD LIKE THE 4TH AXIS TO
ROTATE AS THE CUT IS BEING MADE.

"Rotary" , under Multi-axis

[boopathi.sivakumar]

It is in preview mode and it will be available soon as an extension feature not as a regular feature

[Anonymous]

Yes, I know, but it's still free to use,........ the other way is to program one flat and one fillet then do circular pattern.

[banddspindles]

I DONT SEE IT UNDER PREVIEW MODE?

[banddspindles]

Ok, I am trying to use the rotary toolpath and the tool path looks like this.  I am using circular for rotary passes.  Why is it dipping to a point.  Part is not machining accurate in simulation.

Something to do with diameter of your tool, makes arc over corner fillets then comes down on flat and repeats.

I used 3/8 bull nose and if you look at simulated stock with model turned off, flat is flat, no dip in the middle.

[Anonymous]

Hmmm, not sure that has anything to do with tool diameter, but run a trial and see what it amounts to.

You have option of programming one flat and one fillet then doing circular pattern, using A axis as indexer.

[banddspindles]

So you are saying each face and toolpath should be programmed in a different operation?  This would take a while and doesn't seem like it would be a smooth running program?

[Anonymous]

Program one face and one fillet then do circular pattern operation in Fusion, that will copy same tool path 8 times and index A axis to run each flat,........... one program.

We have seen this one before on the Community, the workaround that we figured out was not to use the "Rotary" but under the "Multi axis" tab select "Flow" and then under the "Passes" tab select the "Multiaxis" option and just go from there, you will need to play around with your stepovers, speeds and feeds for lead in and transitions (Use  Smooth for transitions as in image, Green wavy lines).

If you don`t want to be feeding into the stock directly then just create another model to use for the toolpathing that is longer and then use the original shorter model for the stock length, then you can simulate it properly!!

Hope this helps some 🙂

Screencast of an example.

Ok, this is a work around. It should work... I would like to be able to
use an adaptive clearing toolpath to rough material and have the rotary
moving while doing this. It will not do this for a closed loop or a non
cylindrical face or shape

[banddspindles]

Why is my tool path retracting?

[engineguy]

@banddspindles 

What do you have your "Maximum stay down disatnce" set to ??

It would be much easier for everyone if you ould upload your f3d file, no one has any idea of what your settings are, we are just guessing, looking at your image I have no idea what you have done, have opened the file I uploaded for you?? That works so just use the same settings in your own file!!

Ok, I downloaded you .f3d file.  It has a rotary tool path, which I thought you said use a flow toolpath with multi axis.  Attached is my .f3d and it has my rotary and flow toolpaths.  Please take a look.

So the thing is, bull nose end mill and ball end mill produce slightly different tool paths but both produce flat surfaces.

I guess you could use bull nose to rough faster and ball end mill to get better finish.

[banddspindles]

Yea I am using a square end mill
