    Hobbing a "Grob" Spline

    I am trying to hob a "Grob standard" spline into a part. It is a very obscure type of straight sided tooth form that isn't used very often. We have a cutter that successfully formed the spline on a mostly manual machine several years ago. We are now trying to make it on a newer and more...

    Has anyone seen small bubbling/blistering on a hard black anodize when doing 7000 series aluminum. I've looked around on the net and found many instances of it, but none of the answers or reasons for why it happens or how to fix it agree with one another. Thank you for your help

    Implied Concentricity tolerance on coaxial diameters???

    My question regards a shaft with a through bore and several steps of diameters on the OD, two of which are bearing surfaces. I am a fairly young engineer and somewhat new to GMT, and I'm dealing with a lot of old prints made back in the 80's and 90's. Most of them only contain size tolerances...
