    John, that is too cool! I took me a bit to notice that you where cutting a helix also. Did you make the cutter? Reminds me...I have to get my CNC rotab up and running again once I get my equipment moved into it's permanent home.
    Thanks for the vid!

      John,

      It looks like you're cutting 45 degree grooves instead of involute teeth.
      Is this just a dry run for using a involute gear cutter?

        Geez...I thought I saw an involute shape on that cutter. That's why i asked about the cutter.

          I'm a long way from being ready for an X3 but there's a place staked out in the shop for someday! Yeah. We gotta have one of those ....

          What was with the back and forth action as the cutter was on it's way into the material?

              What good eyes you have Grandmama
              Actually it's 40 degrees.........

              The cutter is just a 20 degree PA rack cutter that was ground up for cutting a long rack for a job.

              These files were just to test the code out and not to make a perfect gear so final shape didn't worry me, I have since ground some true involute cutters up but they haven't cut any gears as yet.

              SP,
              The back and forth action is the fact the machine was on it's transport stand with castors on it's way to a show and was bobbing about a bit as this moves at about 120 in / min in rapids.

                That's pretty slick John -- so you ground a 3-dimensional involute milling cutter?
                Did you use the Unwin 2-disc method, and rotate it 360 degrees as you ground it?

                Pictures, pretty please?

                    Nice vidoes John,
                    I have been asleep at the wheel for a while. Tell us more about your X3. I am looking to move up from my Sherline servo CNC to something that is has a real spindle and a repeatability. (no more threaded rod leadscrew) The Tormach looks nice but it so big I might as well get a HAAS. I am more interested in using than building a machine.
                    Thanks
                    Dave

                      At first I thought this was a flimsy camera tripod. Do you have some beefy steppers or servos? Did you upgrade to ballscrews?

                      Great work to see, keep it coming!

                        Thank you to our families of soldiers, many of whom have given so much more then the rest of us for the Freedom we enjoy.

                        It is true, there is nothing free about freedom, don't be so quick to give it away.
