The part was rotated at 12 RPM as the machined surface was brushed at 3,400 RPM with a five pound load. The part was brushed for a total of 30 seconds.
The part was first brushed with the brush being over the center of the gear teeth. The part made one full rotation in the forward direction underneath the face of the brush, one full rotation resulted in a 10 second cycle time. This process removed the burrs from the top surface of the teeth.
The brush was off-set to the right side of the gear teeth. The part made one full rotation with the part running in reverse, by running the part in reverse the brush was then able to remove the burrs from the one side of the the teeth.
Then the brush was off-set to the left side of the gear teeth. The part again made one full rotation with the part running in the forward direction, this allowed the brush to remove all of the burr from the other side of the teeth. The edges on the gear have been successfully deburred and a small radius generated.
