Machining Spur teeth gear on VMC

Here, I received an another machining challenge. The above gears has there centre offset, that means there bores are not in the center of circle, which further means, they can not be machined by hobbing machine, as it requires fixed center of work piece, around which work piece rotate and teeth are cut. So, we decided to machine it on VMC machine, as the gears did not required much precision, or smooth meshing. To do so, we first designed the tooth profile for above gears, then using CAM, we programmed desired tool motion, and the gear teeth were machined. The fibre gears  have 39 teeths with 4 module. The end mill used on VMC to machine them was of 3mm diameter.
