    Perpendicularity of surface - long edge vs short edge.

    CH, Yes, that's pretty much what I want to do. Do the "EACH ELEMENT" imply that those dimensions will apply at any discreet location along the 48". I know when they check it here, they will probably only measure at 4 or 5 locations, but I want it to be any 4 or 5 locations.

    Perpendicularity of surface - long edge vs short edge.

    I apreciate all of the feedback. Burunduk, I've thought of dividing the part into discreet segments, but as you mentioned, that would be a mess. CheckerHater, I'm not sure how to even inspect a 48" long part in discreet segemnets. I don't know how to set it up in a free state and do that...

    Perpendicularity of surface - long edge vs short edge.

    These are just arbitrary locations along the length of the part. The idea is that I'm really most concerned about perpendicularity between the front of the part and the top of the part at any given location (i.e. at location "1"), but I'm not as conerned about the perpendicularity of the front...

    Perpendicularity of surface - long edge vs short edge.

    I have a part that I'm trying to have fabricated that has length with width ratio of 48:1 (see image). I'm having trouble specifying a reasonable perpendicularity because of this large aspect ratio. The grind houses say they can only hold .002"/12" flatness on datum A shown (over the 48"...

    Methods for processing Silicon Nitride.

    Hello folks, I may as well start by saying that I'm a total newbie and out of my league here... so, here it goes: Can anyone tell me methods by which silicon nitride can be fabricated? Is it a sintering method? Can complex geometries be created? Is the required tooling expensive? Does...
