Regarding discussion on AMC screw driver study, GT has preliminary checked on tool dimension and we found the angle of tools are over than control standard (ISO2768-mk)spec. 90+/-1.
Actual data of all points (12 pts) are in range 93.766 – 94.155 degree. So this also could be one issue that the tools can not fit with Set screw part. See attached file.
(Remark : Red line is from Contour for AMC screw driver against blue line from Set screw part).
As we together know there might be variation of screw bit that we found bigger size (can’t go) and smaller size (can go) to our part in AMC stock.
Therefore, during deep investigate to identify the root cause of this issue, GT would like to request to AMC for segregation the tools in stock and select the small size using for our part.
Could you consider and let us know your concerned?
By the way, we are continue sorting and preparing the full analysis report for next discussion.
