Feed Rate Calculator

Formula

To calculate the Feed Rate (FR):

\[ FR = RPM \times CL \times T \]

Where:

\(FR\) is the Feed Rate (in/min)
\(RPM\) is the Spindle RPM
\(CL\) is the Chip Load
\(T\) is the Number of Teeth

What is Feed Rate?

The feed rate is the speed at which the cutting tool advances along the workpiece in machining processes. It is calculated by multiplying the spindle RPM, chip load, and number of teeth together. The feed rate is crucial for optimizing the machining process, ensuring efficient material removal, and maintaining tool life.

Example Calculation 1

Let's assume the following values:

Spindle RPM (\(RPM\)) = 1200
Chip Load (\(CL\)) = 0.01
Number of Teeth (\(T\)) = 4

Using the formula:

\[ FR = 1200 \times 0.01 \times 4 = 48 \text{ in/min} \]

The Feed Rate is 48 in/min.

Example Calculation 2

Let's assume the following values:

Spindle RPM (\(RPM\)) = 1500
Chip Load (\(CL\)) = 0.015
Number of Teeth (\(T\)) = 3

Using the formula:

\[ FR = 1500 \times 0.015 \times 3 = 67.5 \text{ in/min} \]

The Feed Rate is 67.5 in/min.
