Sorry no picture.
Hi All,
I'm trying to learn the various forms of pocketing with MCX. On attached jpeg (2" diameter, I only care about top surfaces, not backside), I'm able to use the Standard Pocket routine for the 2 center bores (no problem). But.... what is the best way (or any way) to cut the surfaces outside the center post? I was going to use a combination of 1/8" flat and ball end mills.
Issues-
-I am trying to use Rough Pocket function, but... I cannot figure out the Containment feature. It does not seem to contain anything (wants to cut from center out, disregarding my island).
-Is that because I can only select 2D geometry for containment? Why can't I select a surface e.g.; the center post?
-Is it possible to have an inner and outer containment boundary?
Advice is greatly appreciated. Thanks,
Jeff

I would be doing this on a Lathe not a Mill.
Face, Rough Turn, Index Drill, Rough Bore, Rough Tre-Pan, then the finishes. Hold the ID then do the other side of the part.
Is this some kind of Button??
If in case you don't have a lathe you might want to wait for cadcam's reply.

2 operations to rough the inner shape
1- 2D contour ( ramp ) on inner bore with multi-passes on
using the smallest bore size as the profile
2- Rough Surface Pocket
create a patch to cover the inner bore, and create curves on outermost lip on the part
tool = bullnose to suit the part fillets
drive surfaces = select this patch and all surfaces that would come into contact with the tool while pocketing
drive offset = 0.01"
check surfaces = none selected
containment = outer-most profile on the lip- and keep tool inside

Thanks Superman,
Your idea mostly works. But...
-My designs are brought in from Pro-E. When I added geometry in MCX (patch as you call it), it was not selectable as a drive surface. (I modified my part in Pro-e to overcome). How do I change this?
-I can't use a bullnose for ALL surfaces because lower counterbore has sharp edges. Do I always have to mask (patch) over areas I don't want my tool to go into, or is there an inside/outside containment strategy?
And Tobyaxis-
It sure is a lathe job! For those of us that have them. Eventually though, I think this piece will have non-rotationally symetric geometry, so mill will be the route.
And... it's not a button. I'll tell you after I get a provisional patent filed (or after I determine it doesn't work )
Thanks everyone,
Jeff

Are you working fron a solid or surfaces ?
sometimes using surfaces you can have a little more control
import your part as a solid
then create surfaces
<create> <surface> <create surfaces from solid> select the solid and accept
patches
<create> <surface> <fill holes with surfaces> select the surface that surounds the centre bore, and slide the arrow to the edge of the inner bore ( change colors first) and accept
Bullnose will nearly always get material out quicker than a ballnose and will last longer
Jeff if you post the file I can put some paths on it.Is it Alum?

Thanks for the help Superman.
What file format do you have best success bringing in as solid. I succeeded with .sat, but when I follow the create surfaces routine, I get surfaces, but they are apparently overlain on the solid as I get the psychadelic 2 color depiction of part.
Problem #2- this happens to me often, and sometimes I get it to go away without knowing exactly what I did- when using surface rough pocket routine, I select drive surfaces, and the outer containment boundary (inside as you suggest), but when generating operation I get error message(s)- "No cut found-check tool, cut dpths, or use tool containment boundary". Followed by "unable to determine a valid machining zone- no tool path created". Followed by "error regenerating operation! surface rough pocket"
Thanks again,
Jeff
I wpould like to see the native Pro-e file as this what I would bring in and use the solid. most of the cuts are 2d except the convex surface area.

Here is my Pro-E file. It was drawn in Wildfire 3.0 which doesn't open in my MCX unfortunately.

Jeff there is not file. and the wildfire 3 should be supported.

Excuse my file manipulation noviceness, but this software doesn't zip .prt files?
if you are running Windows XP or higher just click on the file and right click and send to Zip.
