Another Surface Rough Help Needed

[Mic6]

Hey people, I'm trying to surface rough flowline the large .130 corner radius around the top edge of this part. As you can see there's a boss interfering with the .130 radius and it's causing the toolpath to plunge into the boss and make a move into an adjacent boss, then begins milling the radius. Why it does this random move is puzzling me. I tried designating the top surface as a check surface, but didn't make a difference.

Toolpath wierdness

check surface the rad you are pointing at and the flat surface it is connects to and is running over.

 

That is not the preferred path I would use.

That is not the preferred path I would use.

 

By all means, I'm open to ALL suggestions!

I would finish that part using all the surfaces using a cutter that has the same or usually smaller

then the rad you are pointing at.

 

So it cuts the rad you are point at and the rad you are cutting with the flowline.

 

 

finish with a waterline with added cuts

Okay, the bosses have a .05 fillet, and my tool has a .03 corner radius. The boss OD is finished, the floor is finished. I'll go try the waterline. thx

It you can send me a file I will give you a path or two you may want to use.

Dang, I'd send a file if I could

We are on the controlled good program if that helps.

Let me pull some surfaces off a couple sections and send that...stand by

Just that corner in the pic will be fine

IMO.

 

I'd put a cap with a radius-ed edge (revolve) on top of the boss and include that in the drive surfaces. You could also just make a flat surface with the same boss dia. up above the boss and include that in your drive. Then I'd use a combination of containment boundaries and depth limits. Lose the rgh flowline tool path. If you need to rgh the corners some, just double up on Waterline or SF Contour. Should be faster, or at least more efficient.

That is similar to what I sent him.

 

i gave Mic the path I would use to finish the rads so it would blend nicely
