Rule of Thumb for Chamfer Dimention in Drilled Holes
Rule of Thumb for Chamfer Dimention in Drilled Holes
(OP)
Hey folks,
We are dealing with a cylinder (rod) with a few full-depth holes drilled cross-wise.
I am wondering if anyone has a rule of thumb for chamfer / fillet sizes for the edges of drilled holes.
Basically, I am trying to figure out if there is a easy way to rough guess at the optimal chamfer / fillet sizes as either a function of the diameter of the hole versus the diameter of the bar or as a function of the diameter of the hole.
I am not looking for any sort of perfect number, but more a conceptual model as to what 'reasonable' looks like...
Cheers!

The primary purpose of the chamfer / fillet is to reduce stress risers that result from non-axial loads.
I recognize that this will vary depending on the angle of the load, but I am not looking for a ideal number. I am more looking for a rule of reasonableness. If you any any such rule you tend to go by even if not perfectly applicable I would be quite interested.
