A client showed me a very interesting part and I’m curious to know if any of you are aware of a tool that could cut its main feature.
It’s a piece of approx 1/8" aluminum sheet/plate that mounts flat on the wall (artwork is adhered to the surface). To accomplish this it has 2 pockets milled out in the back, but what’s stumping me is that the pockets have a cut into the wall of the pocket horizontally IN BETWEEN the 2 sides of the piece to accommodate the head of a flathead screw in the wall.
I’d love to figure out what this is to see if it can be done on my shapeoko. I can’t even find the words to describe this cut so google is useless.
And if it is that hole what Professor examples… there is spesific bits for that . Something like that
and it is possible. Smarter would be slot first with small endmill a chanel and then wit that bit. Dont know if Carbide create can do this kind of toolpath but in f360 it should be possible to give toolpath to create keyhole
@valleyfabrication said the material is only 1/8" thick so a key hole wont work. There are key hole paths in CC now if you wanted to do a keyhole but with 1/8" thick that might be tricky. The Rocker template shows above is the basic shape of the piece you want to cut?
Have you actually seen both sides of the “part?” Most likely the part has another pocket behind the artwork (unseen) that creates that lip (perhaps half the sheet thickness) for the flathead screw.
Thank you for everyone’s thoughts here. I’m thinking it’s got to be a tiny tool like the bits Silverlllak posted. I’m pretty well-versed in F360 so if I can find the tool I can probably figure it out.
You can see the floor of the pocket from the back, it’s not all the way through. It is possible that there is a space underneath the artwork, but the art is thin (paper collage) and mounted extremely flat so I think you’d see it. The person who had it done also indicated that it was machined from one side. However I certainly could have misunderstood him. Done in Zurich, it’s an incredibly finished piece.
Like Tex mentioned, something like this…? Cut from the front side (that the art mounts to).
When covered by the art, it becomes a keyhole pocket. But since you can cut it from the front you don’t need a special bit.
You could even open up the bottom half of the deeper cut making it a true “keyhole”
