Hi all.
I need to form a part with a pretty serious undercut, and I was hoping someone could give me some tips and/or suggestions on tooling design to accomplish this.
Here is a picture of the part in question:
Attachment 206388
The edge you see there protrudes about 3/4" from the part.
I have some ideas about how to go about making the tool, but I don't want to go and re-invent the wheel only to discover there was a much better/simpler way to do it.
Basically, I'm thinking of designing the tool so that the pictured section is detachable and comes off with the part when I pull it, either via some sort of rail system or with a few strong magnets.
Does that sound practical? How do you all go about dealing with undercuts? Any and all tips are welcome.
Other relevant info:
- the tool will be made out of RenShape tooling board
- the part will be formed using 0.125" Kydex 100
- machining the undercut isn't an issue, only finding a way to allow the formed part to be removed vertically (our ovens pull the tool straight down out of the formed part)
Thanks in advance!
p.s. Is "undercut" the correct term for this sort of thing?
