Good Day all. Can anyone throw some light on the size tolerance say of a formed rib. My rib formers (for a 750 cruzer) have been cut on a water-jet cutter. I drew the template , but it is drawn by a series of co-ordinates and you have to connect the dots. This I did by joining them with a bezier curve and then re-drawing by means of arcs , as my cam package does not like Beziers. Secondly, what size holes would you use to prevent tearing/ stress relieving when bending the sides up. Would it be dependent on the material thickness via a ratio ie 10 times the thickness or is there a set rate/ formula, thank you.
