    I have some G10 arriving today to make some prototype plates for the new machine. I've haven't cut G10 before. Any input on the best feeds, speeds, DOC, and bit choices would be great !! Plus will I get a better finish climb milling or conventional? I heard it mills great so i'm looking forward to cutting it. I have 2 pieces @ .375 thickness and one @ .25 if that makes any difference.. I will be using my big machine to cut this so power and stiffness isn't a problem. I also have a "O" flute Onsrud 1/8 bit I can use if need be..

    Thanks

    I'm no expert but I would think you would probably get a better surface finish on G10 with climb milling as long as your mill isn’t prone to backlash. I can't help with feeds and speeds, or DOC as I've never cut the stuff, so consider my response a free bump. :p Hopefully one of the guys here who has milled G10 will see this and respond. :thumbsup:

    LOL, I appreciate the bump but I cut it already.....

    Here are the settings I used for the G10 .25 shank .125 spiral up cut EM .063 DOC spindle RPM 16k and feed @ 30 IPM (50-60 would probably been better, less melting) conventional cut blowing out the kerf with compressed air when you see it clogging up...

    The CE Phenolic was cut at the same settings but because it is canvas laced it may have turned out better with a down cut bit instead... Just a bit of fuzzing, not much though...

    Hopefully this will help someone else in the future...

    Yeah, like I said, you’re going to want to go ahead and use conventional milling. :D
    Thread marked for future reference. :thumbsup:
