Can anyone help explain why/how TABLE 4.3- Performance Qualification - requires root and face bends for thicknesses 3/8 to 3/4" thick , and does not have an alternative to do side bends until 3/4 " and over ?
I thought it might have been a mistake in the 1999 edition, but I now see the same in the 2007.
Procedure Qual does allow side bends over 3/8 (Table 4.2)
Does anyone out there actually do root and face bends on up to 3/4 thickness ?
I know I can calulate the die diameter required , but that puts you up to close to a (2 inch radius) 4 inch diameter bend diameter (Figure 4.9 Nomogram @ 20% elong.) !
If there is an errata, could it not have been corrected after 8 years ?
