I've got a dumb question....... if I see on a blue print that there is a piece that has a corner with a 0.25" bend radius, what exactly does that mean, and how is it measued?

It means that it should be bent in such a way that the INSIDE RADIUS of the bend is 0.25". This could be as simple as using a 0.25" radius press-brake die.

Check the print carefully as some give the radius as inside or outside. If the inside radius is to be 0.25 then a small piece of half inch diameter bar would fit nicely. A typical bend is one thickness inside radius so a quarter inch plate would be bent to such a radius. Often the designer has given the radius so that it fits to a matching corner or he is concerned that the bend is not too tight and will overstress the material. I hate it most when I discover the specification is arbitrary and I have spent extra time trying to get exactly what is specified and then the question arises why it took so long to make up. Randy
