chains in pocket toolpath

[menachem]

I am new to mastercam , have problem with chaining in pocket toolpaths.

even if I draw an simple rectangle , when I try to

reganrate a path , I get an error mesage "

not all baudararies are closed "

how can I close them so I can use the standard pocket ???

thanks in advance

make sure you dont have duplicate entitys..delete-duplicate-entities

otherwise modify -trim- 2 entitys and go around the rectangle to make sure everything is closed.

not sure what version your using either.

If it's a simple rectangle (for a boundary or a pocket), try filleting the chain with a small radius.

I have had the same problem, watch for duplicate chains.

Duplicate entities will be the problem here MOST of the time.

 

If there are no duplicate entities, double check to see that the corners are trimmed properly.

 

If they are trimmed correctly, make sure the endpoints are coplanar.

 

If all of the above are good, check your chaining tolerances and gap settings.

Gap settings?

Simple, but sometimes the problem also.....make sure they are all at the same Z depth. I've had them come out a .001" or .002" different from time to time depending on how they were created.

Oops...Good catch Thad.

 

Checking gap settings only applies when having problems blending surfaces...my bad.

Good call Lans.

Yes, that's exactly what I meant when I said to check to see of they are coplanar. I probably should have explained it better. What I meant by coplanar is that sometimes one endpoint can be at Z+0.0002 and one at Z-0.0002 and they won't chain.

 

When all else fails I usually delete the whole chain and start over by creating new edge curves or lines and arcs.

I have same problem when start with McamX

simple change option for chain:

1 Radio button C-plane

2 option-> Mask -> check closed chain
