I have never sketched serrations before.  I have some data that was provided on the print.  The feature is to be cut into the OD of the part.  Does anybody have a drawing of serrations or can show me what they should look like?   I don't know what all the data below means.


Serration Data:

# of teeth: 99

pitch: 16/32

Nom Pressure angle: 45

Pin Diamter:  .120

Number of pins: 2

Pin measurement: 6.3965 +/- .0005


Would this be a revolve cut around the center of my part?
