It is common for parts cut at different rotations to alter the accuracy of the part by as much as THREE degrees when air bending ordinary everyday parts that are not nested correctly on the sheet. A three degrees bend error can cause a hole alignment error of .25” as well as other accuracy problems. The three degree error is induced into the part by the brake at the time of bending when a part is cut on a sheet of material at 90 degrees to the rotation of the parts that the operator used to setup the brake. In Fig. 4 you will notice that the P.E.P. logic nested the parts at 180 degrees to each other. Therefore, the parts will bend up correctly and as accurately as if the parts were all nested at zero degrees. In Fig. 5 you can see that the Brand-X nest puts parts down at all four rotations 0, 90, 180, 270 . If the end user tries to fab up the parts as nested in fig. 5, approximately 33% or more of the parts will have the bend error of 3 degrees. Therefore, for a competitors nesting products to work around the material grain problem, the programmer must manually interact with the nesting software in a number of different ways, such as selecting a special nesting mode and assigning grain to the parts so that the parts will only be nested at 0 & 180 degrees to each other. Having to nest these parts at 0 & 180 using the Brand-X product will further reduce the number of parts that the competition will nest down on each sheet. Fig. # 4 Note: P.E.P. will nest 27 more parts down ON EACH SHEET.
