Cannot figure out how to machine surfaces

Help.

I am trying to figure out the way to deck down the surfaces in red in the Image. Also machine the round and the "rectangular" Bosses shown. Notice that the round bosses are at a different height than the "rectangular profiles"

I plan to machine those surfaces, flip the Stock and repeat the operations on the other side. Finally hold the block on a Feature using the Holes to profile both parts around.

I have tried different options like a big Pocket with the Bosses as Islands but I end up cutting a lot of air. Also individual Bosses but I cannot or I do not know how to set boundaries to bosses. 

Anybody please help.

Thanks in advance.

Thanks.

hi,

you can use Face with Feature Recognition

it will do just the red faces after that you can do your corners as a contour or in 3D stategies

 

have a nice day

Thanks for your help. 

I really appreciate it; tried different ways but no success.

Thank you again. You save me. Have a good one you too.

Thanks.

Could you please summarize how to apply the contour or 3D strategy? 

Thanks in advance.

Take a look at this quick and dirty approach that is one possibility.

Without diving into it too deep, I'd suggest a Side operation with open curves.

There is absolutely no need for any 3D operation from what I can see.

 

Pick the boundaries, select the correct side to machine, click "Finish Bottom" and use a bullnose for a finishing tool.

Thank you for your help and the fast response.

It is perfect to me, although you see it as a quick and dirty approach.

Thanks a lot.

I really appreciate it. 

Thank you.

Could someone please help me here?

I followed your leads and everything worked right. SetUp1 works perfect.

In SetUp2  "Face3" is coming out bad.  I selected that face and created a Face Feature (Extract with Feature Recognition option activated) just like the other three faces, but this one is wrong.

It wipes out my Bosses.

I cannot see the Stepovers or Plunges Tabs. Totally different than Face5 which works right.

I am attaching an image of an Error Message FeatureCAM is throwing me over and over. Only for that face.

Please take a look.

Thank you in advance

Thanks

Just looking at this part, it seems symmetrical. Could you just run your same program on the other side as opposed to reprogramming everything? Similarly, you could create your other setup and just copy and paste the features into the flipped setup.

This is an ongoing problem in FeatureCam. For some reason it does not seam to follow the same (or maybe I should say opposite) path when approaching a face or side that is at an angle with a radius in it. I have run into this many times. So far no one has come up with a solution that I know of. I ended up doing one part as a side and the other as a face. Now these are 2 identical parts except one is right and one is left. I played around with everything trying to get it to work even sent it to my rep who almost always can get the program to do what he wants and even he had the same problem.

Thank you for your help. I appreciate it.

It seems to be a common problem. Thanks a lot for the time and help.

Thanks

Hi there
Like bhorstTGM48, I do that too and it always works.
That is the right template.
That doesn't happen automatically, you have to lend a hand and work out a strategy.
I wish you success
Sincerely yours

Hallo
So wie bhorstTGM48 mache ich das auch und das funktioniert immer.
Das ist die richtige Vorlage.
Das geht nicht automatisch, da muss man Hand anlegen und sich eine Strategie erarbeiten.
Viel Erfolg
Mit freundlichen Grüßen

Here is another approach.
You can also connect the profiles of the parts to view it as a contour.
There are many ways to do this, but not automatically.
Broaden your horizon and look at it from another point.
Use several roughing tools, still for roughing, finishing, radius extra feature maybe or also extra profiles to minimize the tool path. etc.
I hope I was able to give you suggestions to approach things differently than just automatically.
That is the approach to start.
Otherwise you will never be happy, just as a food for thought.
I wish you success.
Sorry for my english.
Sincerely yours
Mathias Beyer
 
 
Hier noch ein anderen Ansatz.
Man kann auch die Profile der Teile verbinden um es als eine Kontur zu bertrachten.
Es gibt sehr viele Wege dafür, aber nicht automatisch.
Erweitere dein Horizont und betrachte es von einem anderen Punkt aus.
Verwende mehrere Schrupp Werkzeuge, weiterhin für Schruppen, Schlichten, Radius extra Feature vielleicht oder auch extra Profile um den Werkzeugweg zu minimieren. usw.
Ich hoffe ich konnte dir Anregungen geben, mal anders an die Sache heran zu gehen als nur automatisch.
Das ist der Ansatz um zu starten.
Sonst wirst du nie glücklich werden, nur als Gedankenanstoß.
Viel Erfolg.
sorry für mein englisch.
Mit freundlichen Grüßen

Thank you for your help h.goebel.

I will keep that in mind. I am a beginner with FeatureCAM. I appreciate your help.

Thank you for your time.

Thanks
