MMB Calculation - Special Case
[COLOR=#000000][FONT=Tahoma]Hi Everyone,[/FONT][/COLOR]
[COLOR=#000000][FONT=Tahoma]I searched a lot, but wasn't able to find a satisfying answer to 2 specific question regarding Maximum Material Boundary calculation. Maybe I'm missing something simple that someone would be able to point out.[/FONT][/COLOR]
[U]First Question:[/U]
[COLOR=#000000][FONT=Tahoma]Let's say I have a case like the one in the attached picture. I think we can all agree about the various MMB values datum d would take for the first 3 DRF case shown. But what would happen in case 4? (If we were to remove the modifier from datum B) Does it matter? Would the value of datum d MMB be different from case 3?[/FONT][/COLOR]
[U]Second Question:[/U]
[COLOR=#000000][FONT=Tahoma]Let's say we stick with case 3 for this one (DRF A|Bm|Dm). What would happen if the requirements on datum d would change to what is shown? Which position requirement should be used to calculate the MMB of datum D in this case:[/FONT][/COLOR]
[COLOR=#000000][FONT=Tahoma]Should we use the 0.5 requirement because the datums preceding datum d in case 3 are A|Bm and we absolutely need to calculate the MMB with a requirement that use the exact same alignment?[/FONT][/COLOR]
[COLOR=#000000][FONT=Tahoma]Or should we use the 0.4 requirement because it is more restrictive, even if the alignment is not exactly the same as the datum preceding datum d in case 3?[/FONT][/COLOR]
[COLOR=#000000][FONT=Tahoma]Thanks for your help![/FONT][/COLOR]
