## Knurling Formula

The following two example problems outline the steps and information needed to calculate the Knurling.

K = BD / DP

Variables:

- K is the Knurling ( )
- BD is the blank diameter (in)
- DP is the diametral pitch (in)

To calculate the knurling, divide the blank diameter by the diametral pitch.

## How to Calculate Knurling?

The following steps outline how to calculate the Knurling.

- First, determine the blank diameter (in).
- Next, determine the diametral pitch (in).
- Next, gather the formula from above = K = BD / DP.
- Finally, calculate the Knurling.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

blank diameter (in) = 30

diametral pitch (in) = 45

K = BD / DP** **= ?
