SHELLING STRATEGY

SHELLING STRATEGY

SHELLING STRATEGY

(OP)
I often have issues when it comes to shelling parts....Shelling feature failing due to the minimum curvature issue, etc.  I was wondering if people could share there techniques, timing, methods of when to shell the part.  Do you add the details (fillets, cuts, chamfers) to get far along on the part, then roll back to shell?  Do you make the basic form of the part then shell and then continue on adding the fillets, and other small detailing.... that otherwise would cause a shell failure later down the line......etc.?  

Thanks.

John

RE: SHELLING STRATEGY

It depends on the design. I have done it all ways you mentioned above. Most of the time I shell the feature after the feature is complete.

RE: SHELLING STRATEGY

As ctopher states, it depends on the design. If the wall thickness has to remain constant, then shelling after the outside form is complete is usually the best way to go. You will just have to ensure that any outer radii are larger than the wall thickness.

If the inner rads can be non-concentric to the outer ones, then shelling before the outer rads would be better.

An alternative is to create a surface of the required inner form & then thicken outwards.

Another alternative is to create inner & outer bodies, then use the Combine-Subtract function.
