Today I was laughed at by a Program Manager because of my practice of modeling fasteners at worst-case conditions. For example. I modeled flat washers at maximum OD and maximum thickness. The ID is modeled at maximum also to present the possibility of what I call "the worst case locus" of the washer about the screw. This is robust design! For a mounting hole on a printed circuit board, for example, the orbiting of the washer about the screw at worst-case condition could short nearby traces or touch nearby components.
My answer to him was "the CAD model only has to be done once. Once it's modeled then us designers can go about our merry way producing robust, conservative and low-risk designs without wondering how the CAD model is done."
Folks, what would you say to this guy?
I'm working in a place where, until now, they have designed ONLY "onsey-twosy" R&D products. I was hired in part because I have extensive experience in production environments but I am constantly running into "quick and dirty" types who scoff at robust design methods.
