    GD&T for Threaded holes

    Sorry the question was for Eric, I was trying to understand why he thought it would be better to spec the GD&T at RFS.

    GD&T for Threaded holes

    Lots of interesting new discussion here! The hole purpose of the GD&T is to control the set screws location and form. Due to size constraints, the wall here only has about 4-5 threads along the center plane after being counter-sunk. And yes, they are not using CNC mills, just a CNC lathe and...

    Academic/textbook sources for toughness

    SWComposites: Thank for pointing me towards ASM handbooks. Can you tell me more about these handbooks? Are they all collections of academic papers? Or is it more cohesive like a meta-analysis or systemic review? I can see there are multiple authors and DOI's, but they all seem to be published on...

    Would you up issue after DFM?

    My initial reaction to this thread which I fully wrote out was "Why are you asking this on Eng-tips? Do you not have competent colleagues you can discuss this with?" Oh well. I would make sure to take good notes on what you do in this scenario, so that you can document the process. If not for...

    Academic/textbook sources for toughness

    Hey all, I am looking for a reliable academic source on toughness testing data on cast alloys, to provide to CSA. My certifier there is demanding that we do cold impact tests on our aluminum and bronze enclosures, even though bronze is tougher than aluminum, unless I can provide a reliable...

    GD&T for Threaded holes

    GIMP is like that. Thank you for your effort.

    GD&T for Threaded holes

    @Burunduk Since clocking is achieved, I suppose all that's needed is the datums and the location tolerance. @3DDave My logic was this: If you have 2 parallel axes, how can it create a line that passes through both with restricting its position to the plane of symmetry? Sorry if that doesn't...

    GD&T for Threaded holes

    sendithard: I hadn't thought of clocking this... I will give it some thought. Burunduk: Thinking back, I believe my logic was that there was no explicit callout or dimension restricting where the threaded holes should lie. The truth of this is that the position of the holes on the length of...

    GD&T for Threaded holes

    Hi all, My coworkers and I can not agree on the proper GD&T for this situation: We have a shaft, with an offset blind hole in it. There are 2 threaded holes which run perpendicular to the hole. I need the GD&T to indicate that the set screw holes need to go through the thickest section of the...
