5 axis swarf problem

[sharles]

I'm trying to cut a seal groove that isn't flat (it starts out flat, then goes up an angled surface then is flat at the top for awhile until it goes back down the angled surface on the other side, gets back to the flat and finishes). I have to cut it with an endmill so that the bottom is as flat as possible so I'm using a swarf program.

 

The post should really only need to set the C axis at 90 degrees and then after that the tool should move only in X,Y,Z and B. Unfortunately the program is "dancing" around in the C axis. I'm guessing it has something to do with the surfaces I'm using not being perfectly vertical, but is there some way I can set the post or parameters to lock the C axis at 90 degrees and stay there for the rest of the program? I'd only want it to be for this program (not a permanent post edit...and I can't change the post itself because it's locked).

 

Thanks,

I never use surfaces

I use curves

And use proper synchronization

Works like charms

Advice for a starter -never use surfaces too

and you will have no problems

I made the chains but it told me I have to snynch the sharp corners. I read the synchronization help page and tried branch. I guess I'll try all of them and see which one works. Any suggestions?

I typically create curves making certain the endpoints are aligned to produce only an axis movement on which you want then sync by entity.

 

Oh and using entities, you have to have the same number of entities on the top control chain as the bottom. Then it will swarf from endpoint of each upper/lower line to endpoint throughout the chain.

[Teh Bear without Brains kinda idiot]

do you have equal number of entities on upper and lower rails ?

If no ,unite them using create spline command and synchonize to entities

Hey Scott, what are you doing on day's?

 

Sorry I can't be of any help with this one, good luck.

In situations where swarf is dodgy with surfaces I have found that often using curves is as well. Try using curve5x instead of swarf.
