Dowel holes alignment tolerancing/dimensioning
Dowel holes alignment tolerancing/dimensioning
(OP)
I have two mating plates that need to be aligned using 2 dowl pins. Each plate has 2 H7 dowel holes and the dowel pins are m6. Datums are mating surfaces(A) and the sides(B&C). My question is in order for the plates to be properly aligned and assembled, the position of the feature must be within ?? diametrical tolerance zone relative to Datum ABC. Whats the value? How to decide/calculate?
Thank you
Thank you





RE: Dowel holes alignment tolerancing/dimensioning
To avoid overly tight tolerances I suggest keeping the protrusion of the dowel pins fairly short.
You might also want to consider if one of the mating holes can be slotted, this may help depending on your functional requirements.
