Hi all, first time poster looking for some advice please!
I am designing an inspection fixture for a part. One of the datum features is a clearance hole with a tolerance on its position and diameter, but there is no MMC call-out. The hole has no function other than to locate the part on the fixture.
My understanding is that this therefore means there should be no clearance when the part is loaded onto the fixture. What kind of physical pin would I need for this? Should its overall size be limited to the upper spec limit of this feature?
Thanks in advance
