I'm trying to determine what Diametral Pitch was used to produce the knurling on a part. This is a "coarse" diamond knurl on a 0.945" diameter cylinder with 36 grooves around the circumference.
So with P=N/D I end up with a diametral pitch of 38. Correct? Now these parts were made in Taiwan. So metric pitch is in teeth/mm correct? This would give me 36/24=1.5 which I believe to be a standard metric knurling pitch.
I have a customer that is measuring these same parts as a 96 diametral pitch. How is this possible? Am I missing something?
Thanks,
