Finish Flowline path

[Thoob]

Hi, I got another issue with my flowline. i am cutting out a half circle from a 7x7 square part. I have 2 holes in the bottom of the arc. I used create surface fill holes to fill them and added them as a drive surface. The problem now is when I get to the holes, the tool jumps over the holes then comes back down and continues. Because its a 3/4 ball cutter and its only taking .02 cut, it jumps a heck of alot. I hope this is clear enough.

The cleanest way to do this maybe to recreate area as a single surface.

 

When using flowline on multiple surfaces, the direction of the UV lines can quickly become an issue.

 

The other option may be the try using Surface Finish Blend instead

Try makeing a copy of the surface on another level. then use the option of create surface Remove boundy this should remove the holes in that surface.and make it one.other option is to unblank the parent sureface and maybe have to trim it.

See thats the funny thing, I did actually create an identical surface without the holes and it still jumped. This is what stunned me. I even deleted the old surface to try that and it still jumped even though there was no hole at all.

First try Ram saver, in case something is left behind, else, you should start all over again, new file. From the beginning

Try creating a brand new toolpath. It sounds like your toolpath isn't picking up the new surface.

 

Also, try the "remove boundary" command instead of creating a separate surface. If you just use the "fill hole" command, it creates a separate surface and you have to make sure you include it in your drive surface geometry.

 

When you click on the geometry button in the ops manager for that flowline operation, how many drive surfaces does it show? If it only shows (1) then you have not added those new surfaces to your drive surface selection.

 

HTH,

Also try unblank then move the hidden surfaces to another level.

Colin's suggestion might do it. I've had toolpaths work like yours. You fix the geometry and it still sucks. It's like the original toolpath won't let go of something. Sometimes a fresh toolpath with your fixed geometry will work out better.

Also, check gap settings

Gonna try it again. I'll post back.

[Thoob]

Well I tried that it it didn't make a difference. However I changed the path from "follow surface" to "broken" and it only jumps once. Could it be its jumping because there is actually still a hole below the filled surface?

[Verndog]

Depending on how much curve is in the floor often you can set the maximum gap size to an amount larger then the hole, then gap motion to direct and it will force the tool to stay down and cut right across the hole.

I ended up deleting the hole all together and putting a new surface. Its fine now. I just added an arc entity for the drilled hole. Thanks. I'll keep the gap size in mind for next time Verndog. Thank you.
