hello everyone,
I want to take my "making" to next level and have the need to cut some items out of 1/8" carbon fiber.
Think of it making quad-copter parts (although that is not what I am doing).
My question is, what type if end-mill should I be looking to buy and what rpm / feed is this material typically cut at?
Thanks in advance !
CR

yikes.. can't you find me the x3 for $20 version to play with? lol
so then next question is, how do you figure out feed with those crazy multi-flutes
how about this guys:

or this:

Worth a try. I didn't look at the price of that other one, lol. Was in a hurry to post a quick link.

Even PCD-coated carbide may wear rather quickly against carbon fibre. The carbon tends to 'eat' the diamond coating away.
Can you get CBN-coated cutters? CBN is not eaten by carbon.
EDIT: yes you can. Not a new unsolved problem.
The alternative is to see how many units you can machine using really cheap carbide router bits, and to replace them frequently.

Hi Fox I make my own quads from 3mm ply wood its better than carbon fibre and just as light and for about 12 bucks you can make about 10 frames
here is a screen shot of one I just completed this measures 615mm across the center and weigh's 230 grams
this frame is very strong might be a bit of food for thought.
Carbon fibre is conductive and I'm told it can interfere with you transmitter and telementry data signals hard to machine and very expensive.
Wood might not survive a heavy crash but hey niether does carbon fibre first rule of flying don't crash.
you quite welcome to my planes if you want.
Thank your the posts everyone. I will have to try that.
squirrel_41 that looks great. I will keep that in mind for the future. Right now I not making quadcopters. I just uses the analogy for the type of cuts I want to be able to make.
Fox,
Be very careful if cutting Carbon Fiber it is very dangerous to get that dust in your lungs. They usually use machines with filters totally enclosed to ensure no one get exposed to the caustic dust.

If you can find Onsrud 68 series tools - serrated edge solid PCD teeth... I use them for CF as well as G10-FR4. But even they dull after a while, but longer than carbide. What I did was alternatively elevate some sheets, so that I could use a different part of the flute, which gets more use out of them. I only side-mill the stuff, so for pockets and holes I helix in and side mill the full thickness of the sheet. If you try to step down, you'll wear the tip right away, and possibly get it red hot in the process.
Check eBay... they come up once in a while...
