Hi,
I have a 1.5" thick Aluminum anodized block with two 1 " hole in it. The block will be mounted to a base plate. Two 24" long rod(anodized) is press fit into the holes of the block. I have another Aluminum block that need to slide on the rods vertical up and down. Is there a rule of thumb/formula to determine the perpendicularity of the rods and hole tolerance so the the block easily slides up and down.
You haven't specified your requirements, other than one thing needs to move on another thing. What level of precision do you need? Over what length of travel? What are the loads and moments? No bearings or bushings involved?
There is no "rule of thumb" for the situation because there are so many possible variables. Bottom line is that your parallel rods must be exactly that - parallel. And without an understanding of the forces and moments involved you are probably setting yourself up for binding.
A picture is worth a thousand words...
