Kerfing Nomex Panels.
Kerfing Nomex Panels.
(OP)
Thought I'd post this here before heading home for the day. Any ideas about defining an explicit formula for kerfing nomex panels. Right now our shop does this process by trial and error, but we need to determine something more explicit than this quality purposes. I can't seem to come up with anything that will work (beyond trial and error approximations)...
Does anyone know of a formula (or a place to find a formula) that will relate the kerfing cuts to bend radius. (or am i just forgetting some basic geometry here)?

RE: Kerfing Nomex Panels.
For instance, 90 degree bend in 20mm panel, desired outer radius is 100mm. So, the inner skin has a radius of 80mm, so it will need 90/360*2*pi*(100-80) mm of skin removing.

RE: Kerfing Nomex Panels.
2pi * W * D / 360
W = width of board
D = degree of bend
So on 0.400 board you would have to remove 0.628 of skin.
Hope that helps.
RE: Kerfing Nomex Panels.
So gregs example would give outerskin 156.87mm minus inner 125.49. leaves 31.38mm to be divided into sawcuts for your kerf.
