In cases where a manufacturer likes to apply an effective cutting edge hook
angle which is several degrees away from the recommendation, a certain flank
surface twist in the manufactured parts versus the original development (and
the standard CAGE download file) will occur. This problem can be resolved by
utilizing the A3F-file with the effective blade geometry. A tooth contact analysis
using the A3F-file will confirm that Ease-Off and tooth contact still reflect the
original development or will show, that fine tuning is required in order to adjust
the 3-face generated (and manufactured) gearsets to the original development.
In either case, a download file which is generated with the basic data of the
A3F-file (no standard CAGE download file) has to be utilized for the coordinate
measurement.
