I'm looking to gather information on what some of the casting
designers in the group do when they approach a casting design problem.
I've done a few aluminum castings this year, but I am beginning to
fell like I may not be going about it in the most efficient manner.
What I have been doing is to design the part in its machined state
(all of my castings have had significant machining done as finishing
operations). Designing in it machined state allows me to readil
control the position of the machined interfaces realtive to other
parts in the assembly. When I have finished the design of the
assembly and parts, I create a configuration or separate part that
will become the as-cast part. I add machine stock to this to this
part and fix draft problems that I may have left out in the finished
I have found that I do not like the configuration route because I run
into problems with feature suppression and finding parent child
relationships that I didn't expect. Perhaps this is really just
exposing flaws in my modeling techniques...I'm not sure. I do not
consider myself a casting expert, and am definitely learning as I go.
Since there is no one at my company to show me a better way, I am
turning to the collective intelligence of this group. I then plan to
document what I find into a best practices instruction sheet for my
fellow designers to use in the future.
Any input or experiences that can be shared would be appreciated.
