Tapping Speed Calculator

Formula

The formula to calculate the Tapping Speed is:

\[ TS = \frac{N \cdot \text{RPM}}{1000} \]

Where:

\( TS \) is the tapping speed (meters per minute).
\( N \) is the number of threads per inch.
\( \text{RPM} \) is the rotational speed (revolutions per minute).

What is Tapping Speed?

Tapping speed refers to the rate at which a tap or die cuts threads into a material in machining processes. It is usually measured in revolutions per minute (RPM). The appropriate tapping speed depends on several factors including the type of material being tapped, the tap size, and the type of tap being used. Using the correct tapping speed is crucial to prevent damage to the tap or the material and to ensure the accuracy and quality of the threading.

Example

Let's say you have a tap with 10 threads per inch (N) and a rotational speed (RPM) of 1500. Using the formula:

\[ TS = \frac{10 \cdot 1500}{1000} = 15 \, \text{meters per minute} \]

So, the tapping speed (TS) would be 15 meters per minute.
