    Re: floor thickness help

    Having a degree in concrete tech, I can tell you that reinforcement such as mesh or rebar will not keep the concrete from cracking, it will just hold the concrete together where it does crack.

    Re: Alternating Programs???

    I'm not sure exactly what you are trying to do, but could you combine the 2 programs with a M00 in between?

    Bore tapered hole

    I am trying to bore a tapered hole, from .559 to .581, but I don't see a boring option in Bobcad. I tried the turning options, and this is what I get every time. Using V26.

    This is the type of cutter, except with a full radius. The plate will be mounted horizontally.

    Re: Making a wheel

    Fitting the plate in the mill isn't a problem, just making the toolpath in Bobcad/cam. If I had an on-size cutter, this would be easy, but all my cutters are too small and having one made costs $$$....

    Re: Tool quality

    Never heard of the brand, but being on a tight budget I buy my calipers and most everything else on ebay. Most listings let you zoom in close to look at the caliper jaws. :)

    No because you would have to hoist the mill 15 feet up in the air every time you wanted it cleaned.

    Giraffes have a technique for eating leaves off this tree that is covered in long needle like protrusions without getting poked. Perhaps we can learn something from them?

    aaaahh, ok I believe I get it now. I know my machines support linear interpolation. I figured that both axis would travel at the same feed rate with G01, so I figured wrong. Thanks :)
