I’m having a hard time finding a good composite routing service. This is for small parts approx 2x3 in, 1mm thick. I have iges files for them and just need someone to cut them out with just a 3 axis cnc router.
Are you making the parts?
Why not just trim them yourself on a fixture. 1mm parts are flimsy and could be cut with scissors!
I do some clean up on my own with a just a saw, but for a final part i’m looking for something cleaner and more accurate than what I can do.
Make a trimming fixture. It’s basically the same as the composite tool used for layup, but it’s the actual shape and size of the part, and can have drill guides for precise hole locations.
I make my trim/drill fixtures 1/4 smaller than the part all around. This allows me to rest the guide bearing of the router on the edge and follow the contours.
For hole locations, I bond in hardened metal guides over the holes. The holes are in exactly the right place every time.
That’s a good idea TET.
I have been wanting to make some composites stuff and build a 3 axis CNC router, BUT i’ll be having to wait until i have a garage or shop.
Do you have any pictures or instructions on how to make this fixture? I imagine you mean 1/4 inch smaller? Do you use sheet wax to build the fixture? I’m duplicating body panels for an e92 M3 and need to figure out how to get the exact same contours as the original on each panel that I produce. I need some guidance on making this fixture.
I think TET is referencing a “pattern router bit” in a hand held router? I have not seen one that is designed for cutting CF. Usually they cut flush also.
If it is just 2d cutting, look for somebody to waterjet them.
Id be interested in seeing some pictures also
