The Autodesk Community Forums has a new look. Read more about what's changed on the Community Announcements board.

OK, so please let me recap a little.

 

Back when I had a VAR, I knew where to turn to for help.

Never needed it much, but when got cornered a couple of times, they were there just a phone call

or E-mail away to get almost immediate help.

That was one of the perks of being on active Maintenance.

 

Well, that does not seem to be the case anymore.

 

Anyhow, my problem is relatively simple.

I do very little in the way of 3D surface milling, so whenever I come up with a part that needs it I struggle from

beginning to end, and the final result is always some sort of compromise.

Yes, I am at fault here as I just never took the time to dig deep and figure out the various options and methods.

2D programs I believe to have managed quite well over the years, don't remember the last time running up a wall,

let alone needing help.

Let's just say there isn't a paper bag I couldn't program my way out of blindfolded, in the middle of a hurricane while

sipping a cup of coffee.

 

3D part OTOH are absolutely killing me!

 

I will try to attach an FM file for my latest dilemma.

It should be an incredibly simple single 3D surface feature.

Part is an Aluminum extrusion, holes drilled/tapped and the contour is 2D milled to near-net using another operation.

All I need to do is mill the angled surfaces, and I really only need to finish mill them.

That is it!

And yet, I cannot figure out how to coerce FeatureCAM to:

1: Include the vertical wall for machining. It is continuous with all others, and yet it does not touch it.

2: Cannot figure out how to tell it to consider the entire stock when ramping.

3: Cannot define a horizontal ramp distance so it can safely plunge and then feed into the profile.

 

My way around #3 is to do a bottom-up strategy, but that is just a workaround and would not work if I didn't have

a long enough endmill to use.

 

The source solid is an Inventor assembly that is accurately representing the stock and the finished part.

 

If anyone is willing to take a look at the attachment and tell me where am I going wrong,. I do appreciate it.
