◆Technical Challenge: Tab condition for bracket fitment

◆Part Quality Concern: Main issue is tab condition and tab trim tolerance allowed for bracket fitment.

Background:

All two parts have x2 tabs in a closed position but we have been made aware by customer that they require 1 tab to be open for nut plate fitting. In the beginning, the bracket that fits over and is located by the tabs is very difficult fit, both tabs look to be causing an issue that is stopping the bracket from fitting over smoothly without any interference and without having to adjust the tabs. Once the bracket is located under the closed position tab it catches on the open tab, this can’t be fitted unless the tab is bent up more vertical, once steeper the bracket can then slide over and fit into position. Due to this assembly Issue, We thought we need to adjust the trim position to find a happy medium between the both the tab trim edge and the remaining trim from the slit operation. So we discussed with our customer that we need to make a further modification to improve the tab condition to allow for better assembly of the bracket, then modification data from customer sent us to show the required change point to the tab positions. In fact, there are several parts in the same project which have this similar tab condition, so the same modification for these parts with the tab geometry that we implement this into the tooling asap prior to running T3 parts. Finally, improvement of tab condition allowed for better assembly of the bracket.
