    A lot of good data here, good job. If you need any Mitsubishi data hit me up, they have some new grades not listed.
    A good tap chart with thread percentages listed for different tap drills would be awesome, especially STI taps.

    I hope you will find it useful.

    I would really appreciate getting more feedback from the field about bugs and new features that you would like to see coming in the future.


    Many Thanks,

    Nicely done. Thank you.

    Turning Page 4, the calculated IC [inch], seems to actually be a [mm] dimension.

    It's a little cumbersome to use, but your numbers are way off.
    1/2" end mill 1.2 depth of cut,.05" setpover in 4150pht. Set it to aggressive and your numbers are at about 1/2 of the speed I would run it at.

    It's not a bad start, but it needs work.
    Oh and ditch the popups, that will deter people immediately.

    Thanks, you are correct. It needs some digging to fix. I will add it to my To-Do list and fix it soon.

    1) Did you set aggressive for both cutting speed and chip load?
    2) How many teeth/flutes did you set?
    3) With both set to aggressive and 4 flutes I get 3760 RPM with 60 inch/min
    4) What did you get and at what numbers would you run it?

    Thanks,
    Eric

    Thanks for the feedback!
    I added to my To-Do list to add an option to choose HSS/Carbide for solid carbide endmills and drills.
