Hello,
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?
It sounds like circular saw blade specs. Serrations would be the material cut out to form the teeth.
# of teeth: 99 (Total number of teeth around the diameter.)
pitch: 16/32 (Point to point distance on the points of the teeth. Measured in 32nds so it's really 1/2")
Nom Pressure angle: 45 (I believe this is the angle relative to center on the cutting edge of each serration.)
Pin Diamter: .120
Number of pins: 2
Pin measurement: 6.3965 +/- .0005
(Not sure this could be some form of locking mechanism for the saw. I know some smaller grinding wheels have 2 holes or pins depending on manufacturer to lock it onto the axle to prevent it from spinning loose from the machine.)
I'd first extrude a disc with the OD and then use an extruded cut to make a single serration. After that I'd use circular feature pattern of 99 instances.
