One thing I have not yet figured out is how to confidently & efficiently make decisions about wall thickness of Al/PC/etc. tube for various applications. My approach now is to do research here and also look at some comparable applications on past robot CADs published by various teams. And then I’ll make an educated guess. I’d like to do better.
From reading other discussions, it’s apparent an experienced person will often be able to say, “1/16-inch 2x1 6061 will be fine” for this and “better use 1/8-inch” for that.
Is anyone aware of reference information that will help a less-experienced person make tube thickness choices? I could see something simple like a table of rules of thumb being useful. If not that, then it would be helpful to have a set of sources for strength & other material characteristics of the most common types of tube used in FRC and apply that information within engineering calculations. I have searched around, and I’m not having much luck (probably not looking in the right place).
If anyone is aware of helpful resources as described above, please share. I know some teams are moving to using the simulation features within Fusion 360 and other CAD tools. I’m looking into that in parallel. Thanks!
