brake die infomation

[gregvasale]

Several years back I had a temp job for an aircraft parts mfgr operating a press brake. On each machine there was a chart/graph that one used to determine bend allowances/"setbacks" for a variety of metal thickness and top die (punch) nose radii. Anyone have such a chart or know where one may be found? TIA.
