Hi all,
I’m fairly green when it come to GD&T and would appreciate some advice on how best to dimension a hole pattern where one of the hole is a datum. This part (drawing below, dimensions in mm) has already been rough machined but now needs to be sent for jig grinding. There is a mating part with 4 spigots that need to fit in any one of 3 positions (left, middle, right.
Does the hole callout make sense? I am trying give the machinist more margin for error over using standard linear dimensioning.
I would greatly appreciate any insight you may have to offer.
Thanks in advance!
