Enter the feed rate (in/min) into the Plunge Rate Calculator. The calculator will evaluate the maximum plunge rate.

## Plunge Rate Formula

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

**MPR = FR * .50**

- Where MPR is the Maximum Plunge Rate (in/min)
- FR is the feed rate (in/min)

## How to Calculate Plunge Rate?

The following example problems outline how to calculate Plunge Rate.

Example Problem #1:

- First, determine the feed rate (in/min).
- The feed rate (in/min) is given as: 30.

- Finally, calculate the Plunge Rate using the equation above:

MPR = FR * .50

The values provided above are inserted into the equation below and computed.

MPR = FR * .50 = 15 (in/min)

Example Problem #2:** **

For this problem, the variables required are provided below:

feed rate (in/min) = 50

Test your knowledge using the equation and check your answer with the calculator..

MPR = FR * .50** = ?**
