bumbs in my swarf chamfer

[jepkeklinge]

Hey everyone, i want to make a chamfer on a polygon kind of shape.

i am using a swarf toolpath to get it made on a 5-axis machine but i can't get these round kind of bobbels/bumbs or something out of my toolpath.

what can i do to make a smooth toolpath out of this?

Hi @jepkeklinge,

This is pretty strange, historically I wouldn't have expected this issue, my suspicion is that this may have been introduced in an update.  I have spent a good bit of time attempting to correct this but cant get a decent solution unfortunately. Would be interested if anyone else on the forum does any better than me.

The only thing that appears to influence these bumps is the maximum segment length under the passes tab however adjusting this appears to just move the issue around on the model.

Can you submit this to the support department via your Autodesk account as I think it would be worth them taking a look.

Question. Have you cut the part on the machine?

Because to me, it looks like the simulation just messes up. If you simulate and look at the tool it doesn't move that far away from the surface, but the stock does. So I do feel like the path is a lot better in reality than stock simulation might suggest.

I'm in no way saying the toolpath is perfect btw. Just think the simulation is overexaggerating.

Hi @jepkeklinge,

This does appear to be an issue with stock simulation. I have created a bug report so we can investigate this further.

The report number is CAM-26613.

Hello @Laurens-3DTechDraw, and others,

Sorry for my late respond I am not really used to this forum and didn't get any notifications.

I haven't been able to test that part out on the machine, I was looking to buy a machine and was just wondering if I could give it a quick 5 axis test but there was something wrong with the post processor so I could only test some adaptive milling and contour.

I decided to buy it and it is comming this friday, It is a Deckel Maho dmu60t rotary table and a rotating head+5-90or95 degrees I guess.

I sure will test this part when I figured out my post processor problem.

You guys will probably hear some more from me as this is my first own 5-axis mill.

Thanks!!!
