OK, Ill take a stab at it. Is this what you're trying to make?
Thats what im trying to,figure out you see if the clamp is .250 wide and i measure across the bend or radius it gets smaller width wise and i want it to,remain the same all the way around the bend.. See its a water,jet cutting machine part is 1 inch thick but only .250 wide. And i can make radiues anything i want but getting them both right to hold that .250 is a pain.

I agree but most programs have allowances for kerf loss. I think we are still wondering around in space looking for the datum reference point.There is also the issue of kerf loss. So while the radial center must be the same, the actual radius value will not be different by .25. It will be greater by an amount equal to the kerf loss (smaller on the inside, larger on the outside). You have to think of the jet diameter just the same way you would if it were an end mill. Plus the phenomenon of flaring of the jet that makes the kerf wider at the bottom and also the kerf lags at the bottom. Water jets have some oddities about them that present problems with some cuts.
