Toolpath won't go to machining boundary

[Ariel]

I know you are going to tell me it is because the 16mm ballnose and for some odd reason it is unable to machine the area where the vertical wall meets the semi circle sweep.

Is there anything I am missing or I can do to get around it. I have tried all different combinations of containment, offset, contact, fillets etc etc and I can not get a better result that this pictured.

Cheers,

Ariel

This sort of thing it helps if you post the file, it is hard to work out from the picks there are a few things that could do it from what you have selected for the toolpath or stock boundary to stepover, stock to leave or the ramp constraints and leads.

Tool size is not as much a problem as other toolpaths with the parallel op.

[Ariel]

Unfortunately I can't share it.

Containment is the chain just inside the oring groove, same I used for the adaptive clearing toolpath

Lead in/out 1.6mm/10%

No stock to leave

No ramp constraints

You can PM it to me or one of the Autodesk guys will do an NDA.

[Ariel]

I just sent you a PM, thanks

Did you tried scallop strategy???

What is the radius at part. Tool you said is 16mm ball nose, rite??

[Ariel]

Not yet because that's not the toolpath I prefer bit I will give it a try. Yes 16mm ballnose. 

[Ariel]

Same result with the scallop toolpath and reduced to a 12mm ballnose

[daniel_lyall]

Now that I have had a proper look to try and fix this silly problem I can not, there is something completely wrong with the model or the cam workspaces it will not get closer than 20mm to the area in the pic, fusion staff members will need to have a look.

@jeff_strater can you plese have a look at this and see if you can work out what is wrong.

[Ariel]

I had a funny feeling something like that might be wrong because regardless of the tool or toolpath used which is giving me similar end result

@daniel_lyall share the file? You got my email address (if that's okay with @Ariel )

[Ariel]

@daniel_lyall no problems at all with me on you sharing it with @seth.madore 

[seth.madore]

@Ariel  just email it to me, it might be quicker. Daniel is on the other side of the world, it's late evening there for him.

Alright, I've got answers!

All the 3D Toolpaths are "model aware", in that they "see" the part. It's not actually the part you see on screen, but rather, a generated STL that occurs in the background, nothing that we can see.

However! We have the option in modeling space to "Export as STL". With the tolerance set low enough, we export and bring it back in, and get this:

What in tarnation is that?! I don't know, but I am opening up a ticket. 

So, how do we get around that? Go into your Parallel toolpath and open up the tolerance to .017. This will create an STL that does NOT have that doughnut....

Thank you again Seth!!! It means I don't fall behind schedule which is what I was fearing.

Keep me posted on the details of the ticket.

Cheers,

Thank you, Seth you're the man, Another thing to remember to check for.

[seth.madore]

Full disclosure; I didn't find that out on my own. We can thank @porsbym  for showing me the way on that.

Fwiw, the problem also shows up in Inventor
