    Re: Feeds and Speeds 6061

    If you can find a 2 or 3 flute endmill it would work better.

    I would break the depth of cut in half and do .75 at a time with HSM. 1.5" might be too much for one go at it. I usually do a 30 -...

    Re: production run issues w/ ST20-SSY

    I believe you want G10. I have used it on a ST30-SSY successfully. This won't work on the HAAS Mills, the code is slightly different.


    For Lathe:

    You can go as slow as you want as long as the machine has the torque to do it. There really is not a upper or lower limit with aluminum and carbide tools. At the upper end the problem becomes being...

    Re: Aluminum CNC Question

    I'm going to say the problem is the single flute cutter. Try a 2 or 3 flute with your feeds and speeds. Single flute end-mills are mostly for routers and\or cutting plastic.

    Re: Thread Milling rules of Thumb

    5/16" isnt that small as far as threaded holes go.

    Climb milling gives you a better finish. Bottom to top for a right hand thread.

    Re: Finish Passes

    Cut and paste your roughing toolpath operation. Take out the multipasses or depth cuts so all that is left is the finish pass operation after the roughing operation.
