I have a piece of aluminum flat bar that needs a dado along its length, and pockets milled out intermittently. At the bends I want to mill out v-grooves so that the part can be bent by hand. The image below shows what I'm trying to accomplish, the arrows indicate where the v-grooves are after folding the part. This model is attached as "No Features Model - V-grooved - Goal.SLDPRT", it is imported from another program with no features .
I've spent a good deal of time just getting the milling operations modeled (tried a lot of routes), while retaining the ability to flatten the part. I've found a somewhat clumsy method to get to this point, but now I'm stumped on getting the v-grooves modeled. I've tried unbending and performing various cut operations, simple normal cuts, and remodeling as a flat solid and adding bends, without success. Below is a screen shot of where the part currently sits. This model is attached as "Sheet Metal Model - Needs V-grooves.SLDPRT".
I've tried to search this on a number of sites, but coming up short handed. Any ideas or a point in the right direction would be very very appreciated!
