    Stack-up Analysis Calculation

    Maybe a stackup is not the right thing to do here. Should I just look at the worst case for each individual dimension? For the diameter size and the flat height.

    Stack-up Analysis Calculation

    Ok, so I am just looking that there is no interference for the adapter to be inserted into the coupling and that there is any interference between the flat at .100 on the adapter and the corresponding flat in the coupling when inserted deep enough. The depth of that flat in the coupling is not...

    Stack-up Analysis Calculation

    The objective is to verify that the given dimensions and tolerances allow for a secure connection between the two parts.

    Stack-up Analysis Calculation

    I am new to stack-up analysis and need some help for a simple calculation. It is for the connection between the two parts shown below. For the coupling those are the only two dimensions that are defined, so we are only concerned about the two corresponding dimensions on the Adapter. Can someone...

    How to measure true postion

    1. ASME Y14.5M-1994 2. I have read section 2 3. Datum A is the outside face of that cylindrical surface 4. Datum A is Ø1.614 ±.005. Same dimension applies to the other 4 portions of the circle. 5. Datum B is the flat surface on the opposite side of this view. 6. STARLITE GX OPTICAL MEASUREMENT...

    How to measure true postion

    Hi, I am having a hard time understanding the true position for the Ø.199 holes in this drawing and how to measure them during inspection. When the hole diameter is the smallest allowed or at MMC(.198) the center position of the hole can vary by Ø.002 from the true position. Is that correct...
